Overview of WSAA
The Water Services Association of Australia (WSAA) is the peak industry body that supports
the Australian Urban Water Industry. Its members and associate members provide water and
sewerage services to approximately 20 million Australians and many of Australia’s largest
industrial and commercial enterprises.
The Association facilitates collaboration, knowledge sharing, networking and cooperation
within the urban water industry. It is proud of the collegiate attitude of its members which
has led to industry-wide approaches to national water issues.
WSAA can demonstrate success in the standardisation of industry performance monitoring
and benchmarking, as well as many research outcomes of national significance. The WSAA
Executive retains strong links with policy makers and legislative bodies and their influences,
to monitor emerging issues of importance to the urban water industry. WSAA is regularly
consulted and its advice sought by decision makers when developing strategic directions for
the water industry.
WSAA was formed in 1995 as a non-profit organisation to foster the exchange of information
relating to the provision of urban water services between industry, government and the
community, and to promote sustainable water resource management.
The Association’s main activities focus on four areas:
1. Influencing national and state policies on the provision of urban water services and
sustainable water resource management;
2. Promoting debate on environmentally sustainable development and management of
water resources and the community health requirements of public water supplies;
3. Improving industry performance and establishing benchmarks and industry leading
practices for water service processes; and
4. Fostering the exchange of information on education, training, research, water and
wastewater management and treatment and other matters of common interest

The new standard EN 545:2010 does not specify pressure class for the vonRoll DI fittings.
Only the minimum wall thickness is mentioned which relates to the wall thickness class K12
for all fittings; i.e. socketed and flanged.
Standardised lengths of DI pipe are permitted in EN 545 / EN 598 and are a function of pipe
size and joint type. Reece are offering to supply standard DI pipe lengths of 6 m length for
spigot / socket pipes and maximum 5.9 m length for flanged pipes.
Reece only intend to import a small quantity of the Class K12 pipe (PN 16 rated) for
manufacture of flanged pipe (screwed on and bonded).

The Rubberring with steel teeth (Fig. 2807A and Fig. 2807B) is a vonRoll product, which is
manufactured and supplied by Rex Articoli in Switzerland. Their function is only to restrain,
not tightness.
The Rubberring with steel teeth (Fig. 2807A and Fig. 2807B) is different to TYTON ®-SIT ®
and TYTON ® SIT PLUS®, which are products of Hultec and have both functions in one ring,
i.e. tightness and restraint.
The Rubberring with steel teeth (Fig. 2807A or 2807B) internal restrained joint cannot be
used by the ECOFIT DI fittings supplied by Keulahütte as they have only single chamber.
The groove of the single chamber is used for unrestrained HYDROTIGHT seal TYTON ®
EPDM (water) Fig. 2810 NBR (sewer) Fig. 2811.
The single chamber ECOFIT DI fittings will be restrained in three ways (one internally and
two externally) as detailed in Section 3.4.2.

3.4 vonRoll ISO sized ECOFIT DI fittings
FIGURE 15: VONROLL ECOFIT DI FITTINGS (BLACK OR BLUE - WATER SUPPLY;
RED BROWN OR BLACK - SEWERAGE)
Ductile iron fittings are sand cast in accordance with ISO 2531 and with EN 545 / EN 598.
All the fittings are in the class K12 and the thickness of the fittings is in accordance with the
European Standard EN 545 / 598. The fittings are subjected to a leak-tightness test carried
out with water in accordance with ISO 2531 and with EN 545 / EN 598.
The DI fittings are provided with an integral Resicoat R4 epoxy powder coating (internal and
external) at least 250 μm thick according to EN 14901 and GSK, perfectly suited to all types
of soil. GSK is a trade association (Gütezeichen) that has been registered in Germany for
over 20 years which acts as the global network for companies that coat val ves and fittings
with an epoxy powder coating. For more information refer to http://www.gskonline.de/en/gsk.html
The coating made from epoxy resin powder (black epoxy pulver coating) provides proven
and pore-free corrosion protection for fittings used in water and gas supplies and for
wastewater disposal. The extremely smooth and pore-free epoxy internal coating offers
comprehensive protection for drinking water and meets all legal requirements on hygiene in
full. It prevents deposits from building up and is abrasion resistant. The epoxy coating is an
organic protective coating and its use has minimal environmental impact.

The manufacturing standards EN 545 and EN 598 used for the vonRoll DI pipes have similar
performance requirements to the DI pipe manufactured to AS/NZS 2280 where testing of
dimensions, mechanical properties, joint performance and pressure testing are all performed
on the pipes during manufacture. The ductile iron has equivalent mechanical properties to
AS/NZS 2280 i.e. minimum tensile strength of 420 MPa and minimum elongation of 10%.
As part of agreement no. 117455 dated 12.05.2011 between the client vonRoll hydro
(Suisse) ltd and the MPA NRW (Third party certification body) audits are conducted yearly
at their factory in line with Technical test specifications; DVGW GW 337-81, DIN EN
545:2010 and DIN EN 598:2007.
vonRoll has submitted an English translation of MPA NRW annual audit report no. 11 7455
14-01 for DUCPUR® and ECOPUR® to EN 545 conducted on 16 th and 17 th of April 2014.
In addition, vonRoll has submitted MPA NRW’s 2015 annual audit report no. 11 7455 15-01
for DUCPUR® and ECOPUR ® to EN 545 and report no. 11 7417 15-01 for GEOPUR ® to EN
598, in German. The audits were conducted on 15 th and 16 th of April 2015 and reports were
issued on 28 th April 2015 in German language. By the annual visit, MPA NRW looks at three
different executions of the pipes and associated fittings, simultaneously.
The certification from MPV NRW is accepted as sufficient conformance requirements for the
DI pipes and fittings. In addition an onsite review of the manufacturers testing data and the
process control also provide sufficient information to demonstrate compliance with both
standards EN 545 and EN 598.
WSAA has sighted the above MPA NRW annual audit reports and saved in the folder.
6.2.3.1 Type tests and audit reports for vonRoll DI pipes
vonRoll have a number of audit reports on DUCPUR ®, ECOPUR® and GEOPUR® but the
content is almost the same. By the annual audit, MPA NRW checks the routine tests in the
production as wall thickness, lining, coating, mechanical characteristics of the material,
dimensions, etc. The type tests do not fall under the scrutiny of the annual audit because
they should be renewed only in case of a new development (i.e. new connection system,
change in material or design etc.). vonRoll did a comprehensive type tests in accordance
with EN 545 and EN 598 few years ago and the results are still valid.
The type tests for GEOPUR ® DI pipe to EN 598 is similar to those of DUCPUR® and
ECOPUR ® DI pipes to EN 545.
vonRoll has submitted full report on type tests conducted for GEOPUR ® DI pipe which was
recognized by the MPA NRW for issuing the third party product certification to EN 598.
vonRoll has also submitted MPA NRW audit report for GEOPUR ® DI pipe to EN 598 but it is
in German.
The type tests and audit reports associated with EN 598 have been sighted by WSAA and
saved in folder. As these documents are treated as “Commercial-in-Confidence”, anyone
need access should obtain the consent of the supplier Reece.

6.2.4 Pressure ratings
The pressure rating of ductile iron pipes and fittings in EN 545 depends on:
a) Nominal size
b) Class designation (pipes) - see Section 6.2.2.1 below
c) Joint type
d) casting type (pipe / fittings)
COPYRIGHT
WSAA Product Appraisal 1430
32
6.2.5 Pipe class designation
The previous standard EN 545:2006 defined the classification of pipe and fittings, not related
to pressure rating but instead to coefficient “K" which when substituted in the following
formula specifies the minimum wall thickness for various nominal diameters with an absolute
minimum thickness of 6 mm for pipes and 7 mm for fittings.
e = K (0.5 + 0.001DN)
Where e is the nominal wall thickness, in millimetres:
DN is the coefficient used for the determination of the thickness. It is selected from a se ries
of whole numbers 8, 9, 10, 11, 12.
The latest standard EN 545:2010 against which vonRoll DI pipes (DUCPUR ® and ECOPUR®)
for water supply applications are manufactured, defined the pipe classification in Clause 3.21
as follows:
The pressure class of a component is defined by a combination of its structural performance
and the performance of its non-restrained flexible joint. Restrained joints may reduce the
PFA; in this case the PFA shall be declared by the manufacturer.
Pressure class (C) - alphanumerical designation of a family of components, including their
joints, relating to their operating pressures as verified by all the performance tests described
in this standard, which includes the letter C followed by a dimensionless number equal to
the maximum PFA in bars of the family of components.
As per Annex A of EN 545:2010, the maximum values of PFA, PMA and PEA are calculated
as follows:
a) PFA = (20 x emin x Rm) / (D x SF)
Where
 Emin is the minimum pipe wall thickness, in millimetres
 D is the mean pipe diameter (DE – emin), in millimetres
 DE is the nominal pipe external diameter, in millimetres
 Rm is the minimum tensile strength of ductile iron, in MPa (Rm = 420 MPA)
 SF is a safety factor of 3
The maximum PFA of a pipe is equal to its class number, e.g. PFA 40 for a class 40
pipe.
b) PMA: as PFA, but with SF = 2.5; therefore:
PMA = 1.2 x PFA
c) PEA = PMA + 5 bar
6.2.5.1 Pipe Classes for Water Supply Application
Pipe classes for water supplies is in accordance with EN 545:2010 and ISO 2531:2009
standards
a) Pipes with push-in sockets: Pressure Class C / Thickness Class K9
b) Pipes with flanges: K12 standard
The pressure performance capability of DI pipes and fittings for water supply to EN 545:2010
is shown in Table 2.

* NOTE: vonRoll decided to put only the K9 thickness class for the DN 500 up to DN 700 in their catalogue but the
marking on the pipes is as follows:
DN 500 K9 / C30
DN 600 K9 / C30
DN 700 K9 / C30
PFA: Allowable Operating Pressure
Maximum hydrostatic pressure that a component is capable of withstanding continuously in service
PMA: Allowable Maximum Operating Pressure
Maximum pressure occurring from time to time, including surge that a component is capable of
withstanding in service
PEA: Allowable Test Pressure
Maximum hydrostatic pressure that a newly installed component is capable of withstanding for a relatively
short duration, in order to insure the integrity and tightness of the pipeline
The allowable operating pressure for pipe classes C100, C64, C50, C40 and C30 of DI pipe (i.e.
10 MPa for 80-100; 6.4 MPa for 125-200; 5 MPa for 250-300; 4 MPa for 350-400; more than 3.38
MPa for 500-700) far exceeds the pressure needs of water supply systems which is usually 1.6
MPa.
Allowable operating pressures for DI pipelines will be dependent upon the rating of elastomeric
seals, flanges and appurtenances.
NOTE:
Applicable limits, which may not permit the full use of the pressure ranges as stated in Table 6 in an
installed pipe, must be taken into consideration.
For example:
- Operation at the PFA and PMA values given in Table 6 for socket pipes can be limited by the lower
pressure range of other pipeline components, e.g. flange pieces (Table 8), certain types of Y-fittings and
certain types of moveable connections.
- The water pressure test in pits with the high PEA values given in Table 6 can be limited due to the type
and structure of the anchoring system of the pipe and/or the moveable connections.

Internal lining
FIGURE 20: INTERNAL LINING OF ECOPUR ®, DUCPUR® AND GEOPUR® PIPES
The polyurethane is composed of a two component resin. It’s three-dimensionally linked
molecular structure gives its mechanical stability. Polyurethane is a thermosetting plastic
with no solvents. Specific details of the polyurethane characteristics are shown in the vonRoll
Catalogue.
Each pipe is being grit, blasted twice and pre-heated before lining in order to obtain perfect
adhesion and curing. The smooth surface and the equal distribution of the polyurethane are
achieved by keeping the pipe in rotation during lining and coating.
The interior of the socket is fully protected with polyurethane for ECOPUR® and GEOPUR ®
and with bitumen for DUCPUR ®. The socket of the DUCPUR ® pipes can be also lined by
polyurethane.
The thickness of the polyurethane lining shall be as follows:

6.2.10 External Coatings
6.2.10.1 Polyurethane coating for ECOPUR ® ductile iron pipes
The coating of the pipes consists of a factory applied polyurethane coating. Each pipe i s
being blasted and pre-heated before coating in order to obtain perfect adhesion and curing
in accordance with EN 15189 DI pipes – External Polyurethane coating – requirements and
test methods.
The thickness of the polyurethane is nominal 900 microns with a minimum of 700 microns.
The entire barrel included of the spigot end is coated with polyurethane. Minor coating
damage (during delivery etc.) can be repaired with an easy to use dual pack cartridge which
ensures the exact dosage of resin/hardener components. See vonRoll Products Manual.
6.2.10.2 Zinc and finishing layer for DUCPUR® and GEOPUR ® DI pipes
The DUCPUR® and GEOPUR® DI pipes are internally lined with a Polyurethane (PUR) but
are externally protected with zinc coating in accordance with ISO 8179-2 Ductile iron pipes
- External zinc-based coating - Part 2 : Rich zinc paint with finishing layer. vonRoll hydro
applies the coating at a minimum of 220 g/m 2 zinc layer as prescribed in EN 545 for
DUCPUR® and at a minimum of 150 g/m 2 as prescribed in EN 598 for GEOPUR®. The zinc
coating is applied to the substrate of the ductile iron pipe by spraying of paint reach of zinc
(min. 90%).
DUCPUR® ductile iron pipes have a black bituminous paint applied as a finishing layer to a
minimum thickness of 70 μm.
GEOPUR® ductile iron pipes have a red brown bituminous paint applied as a finishing layer
to a minimum thickness of 70 μm.
The polyurethane lining is applied only in the pipe barrel for the DUCPUR®. The socket is
lined with bitumen. The socket of the GEOPUR® is lined with polyurethane.
The application of zinc coating enhances the external corrosion protection of the pipe and
fittings in buried applications. Zinc coating has not historically been widely utilised on ductile
iron pipes in Australia, however zinc based corrosion protection systems have been used in
Europe for more than 60 years. The application of this additional corrosion protection is
considered to be acceptable and beneficial to the performance of the pipe. In many soil
conditions it is possible to install zinc-coated pipes without polyethylene sleeving.
6.2.11 Polyethylene sleeving
Most Australian Water agencies specify polyethylene sleeving of ductile iron pipes as a
means of corrosion protection. Polyethylene sleeving provides corrosion protection in
aggressive soils by creating a passive uniform environment around the pipe and limiting
oxygen exposure.
Loose PE sleeving is installed on site on ductile iron pipelines in the form of a tubular film.
Cut lengths are slipped over the pipe, overlapped and wrapped up tight before securing in
place with bands and plastic adhesive tape. Polyethylene sleeving should be installed in
accordance with AS 3681:2008 - Guidelines for the application of polyethylene sleeving to
ductile iron pipeline. As the sleeving is the primary corrosion barrier, care needs to be
exercised during installation to prevent damage. Only accredited pipe layers trained in the
application of sleeving should be employed.
ECOPUR ® DI pipe does not need the sleeving because of its polyurethane external coating
and DUCPUR® and GEOPUR® DI pipes with its zinc/bitumen coating only requires sleeving
where the soil conditions are known to be corrosive to ductile iron.

FITTI NG INSTRUCTIONS , TR AI NING AND I NSTALL ATIO N
7.1 Installation Instructions
Installation methods for DI pipes are generally in accordance with AS/NZS 2566 Buried
flexible pipelines Part 2: ‘Installation’. The standard specifies the requirements for the
installation, field testing and commissioning of buried flexible pipelines with structural design
in accordance with AS/NZS 2566.1.
Installation, repair and maintenance of vonRoll DI pipe is the same as for all DI pipe systems
and should cause no problems for installers or maintenance personnel. When an ECOPUR ®
pipe is cut, the exposed end can be coated with polyurethane which is supplied in a dual
cartridge applicator which ensures the components are mixed in the correct ratio. The same
cartridge applicators are used for minor repairs to the Polyurethane coating.
The vonRoll Product Catalogue show detailed installation instructions and full details on
carrying out minor repairs to the coating using the cartridge applicator. However, a range of
restrained and unrestrained mechanical couplings and flange adaptors are available to
enable end connections between CIOD to ISO pipe sizes, in order to maintain pipeline
systems.
7.2 Ductile iron fittings
A complete range of ECOFIT branded ISO sized ductile iron bends, tees, tapers and
connectors of size DN 80 to DN 700 are available from Keulahütte GmbH in Germany. Reece
also supplies AS/NZS 2280 manufactured socketed DI fittings for use with vonRoll DI pipes
using Gulf Rubber’s special adaptor seal for size DN 100, DN 150, DN 200, DN 250 and DN
300.
7.3 Tapped connections
ECOPUR ® and DUCPUR ® ductile iron pipes may be direct tapped with or without a suitable
tapping saddle. However it is suggested the practice of drilling holes in the pipe be minimised
where possible and that the use of Pre-Tap Connectors be utilised in new installations.
vonRoll DI pipes, ECOPUR ® and DUCPUR® can be tapped for customer service connections
with or without tapping saddle using a ferrule or ball valve. For more information on direct
tapping of DI pipe refer to vonRoll hydro.
If the polyurethane coating or lining is damaged during this process please refer to 7.1 repair
lining and coating.

SUPPORTS
FIGURE 28: SPACERS
The normal method of transporting vonRoll ductile iron pipes is as follows:
•
DN 80 to DN 300 Socket / Spigot DI pipes are delivered in bundles (packs).
•
Pipes larger than DN 300 are delivered as single pipes.
vonRoll DI pipe bundles are covered with UV protective film. This covering should only be
opened when necessary and should be closed again afterwards. Each pipe is sealed on
socket and spigot end with caps. Experience to date shows there has been very little damage
to the pipe coating during transport from Switzerland.
Only wide synthetic lifting belt should be used when loading and unloading the pipes to
prevent damage to the polyurethane coating.
Piping components made of elastomers, e.g. EPDM jointing rings, can be affected by heat,
light, ozone, dampness, solvents and storage under tension. For this reason particular care
must be taken with the storage and handling of these items. Precautions include:
•
Max temperature 25°C and Minimum -10°C
•
Keep away from UV light
•
Relative Humidity under 65%
•
No ozone exposure e.g. keep away from electric motors

14 WATER AGENCY EXPERIE NCE WITH THE PRODUCT O R FIELD TESTI NG
REPO RT
Examples of long and short-term use by the water industry were sought. The longer-term
information focused on the polyurethane coating performance and was obtained overseas.
The shorter-term experiences of local water Agencies were obtained to gauge installation
practices.
14.1 Long Term
The polyurethane lined pipe and more recently the lined and coated pipe has been used
widely by Zürich Water in Switzerland since the product was first developed in 1972. Some
problems were encountered with the first generation internal lining that resulted in a change
of coating formulation. The original polyurethane was of the flexible type and when this
showed signs of blistering, further research was carried out which led to the development of
a rigid polyurethane version. This later generation of coating has much higher adhesion
strength to the ductile iron that provides superior performance. The change to rigid
polyurethane was made in 1978.
A section of first generation pipe was inspected which had 20 years’ service and while this
showed considerable blistering, minimal rusting of the substrate was apparent. It was
reported that similar aged rigid polyurethane pipe performed very well without any blistering
or deterioration. Zürich Water have also carried out controlled tests since 1990 to monitor
the performance of the ECOPUR ® and DUCPUR® pipes in different soil types and at the end
of 1998 they are satisfied with the results.

14.2 Short Term
Locally, City West Water in Melbourne has been using both ECOPUR ® and DUCPUR ® pipes
for approximately 16 years. Feedback from the construction crews has been positive and no
major problems have been encountered. It was reported that it was easier to lay the pipe as
the jointing pressures being quite low. The pipe was also easier to handle and there did not
seem to be a major problem in external coating damage to the ECOPUR ® during normal
handling.
On a precautionary note, a greater input into the supply logistics is required to ensure that
the correct fittings and adaptor rings are available and supplied. The repair coating used to
make good cut ends of the pipe also took considerable time to cure but this was usually
avoided by better planning.

REP AIRS TO POLYURETH ANE COATI NG
Users should be mindful to watch for external damage to the polyurethane coating of
ECOPUR ® DI pipe as it may be difficult to detect damage in a black coating on a black pipe.
One product is available for the repair of the polyurethane coating and lining. Repairs are
recommended when ECOPUR® pipes are cut or damaged. The repair material is an epoxy
repair kit. The epoxy repair kit is used for repairs of smaller surfaces, e.g. cut ends up to DN
300 and repairs with area up to approximately 100 Sqcm. Either repair kit can be used on
the interior green lining or exterior black coating. Similarly where cut or drilled holes are
made in the pipe, repairs should be made or if that procedure is carried out under pressure,
an anti-tuberculation insert should be provided to prevent blockage of the outlet. As stated
in Section 7.3, where possible the Pre-Tap Connectors be utilised in providing new services
instead of drilling holes on the pipe to provide services using ball valves / ferrules and tapping
bands.
Zürich Water is one the long term users of vonRoll DI pipes. Feedback from Zurich Water
indicated that they no longer repair cut ends as the level of corrosion is minimal and is
unlikely to constitute a future failure point in pressure mains.

DISCUSSION
vonRoll has pioneered polyurethane materials for use as a pipe lining and coating over the
last 42 years. During this time the product has been used extensively in some European,
African and Middle East markets. The direct information from one of the larger and longest
users, Zürich Water, has been positive with excellent performance reported.
The polyurethane coatings are now being adopted by some pipe manufacturers in the USA
and several recent technical papers have provided testing data of various pipe linings. While
the data does not provide any details of long-term performance the information does provide
data which demonstrates superior physical properties of polyurethane coatings compared to
other more conventional linings. This information from users and current trends in other parts
of the world give confidence that the vonRoll product will provide a long life pipe system.

One of the advantages of this pipe is the relative inertness of the lining that has no adve rse
effect on the water quality. Additional corrosion protection is not required with the ECOPUR®
pipe.
The literature claims that the ECOPUR® pipe can be directly backfilled and buried with the
original trench excavation material. The polyurethane coating has high levels of adhesion
and is reported to have high resistance to damage and undercutting. If the external coating
is damaged, corrosion will occur and depending on the extent of damage a perforation may
occur in the longer term. While in some cases the use of trench excavation material could
be used, a number of risks emerge if this practice is adopted.
Increases the risk to damage if stony or rocky material is used up to 60 mm size.
Some trench excavation material, bigger than 100 mm, would be very difficult if not
impossible to compact which would be a problem under a carriageway.
In general it is felt that for maximum protection, selected bedding and backfills should be
utilised to minimise damage to the external coating. It is recommended to use bedding
material as sand or gravel up to 32 mm size.
In a similar context the DUCPUR ® pipe with a combined external coating of zinc and bitumen
is claimed to overcome the need to use loose fit polyethylene sleeving in low corrosivity
soils. The use of the zinc/bitumen external coating is widely used in some parts of the world
without sleeving and specific criteria has been set down where sleeving is and isn’t required.
Similar criteria can be used for ductile iron with a bitumen coating but the majority of
Australian Water agencies have adopted the policy of full sleeving of all ductile iron pipe with
zinc/bitumen coating. It is well documented that the application of a zinc coating will not
detract from the performance and in some environments there are definite improvements to
the performance of the pipe. Unless the environment is known to be low corrosivity, the use
of the sleeving in conjunction with the DUCPUR ® pipe is recommended.
Like all pipes, it is better to avoid the cutting of holes which can act as points of corrosion or
stress failures so it is felt that the use of pre tapped connector fittings for the connection of
services should be adopted in the first instance to minimise this effect. Where holes have to
be cut the use of plastic inserts is recommended to prevent the growth of rust tubercles that
can reduce flow in the longer term.
For the tapping of the vonRoll ECOPUR® and DUCPUR ® DI pipes, there will be no damage
to the coating and lining if the right equipment/device is used. Tapping wit h saddle under
pressure is always possible for the vonRoll DI pipes up to and including DN 400.
If copper services are used in conjunction with these pipes it is essential to use insulated
fittings to prevent galvanic attack of the ductile iron.

LIFE EXPECTANCY
Operational experience with cast iron pipe in Australia has shown a life expectancy of over
100 years. The new generation of ductile iron pipes with the specialist coatings can only be
expected to extend this life even further. On this basis an operational pipe life of well over
100 years can be expected.
The manufacturing standards used for the pipe have similar performance requirements to
AS/NZS 2280 in that testing of dimensions, mechanical properties, joint performance and
pressure testing are all performed on the pipes during manufacture. The ductile iron has
equivalent mechanical properties to AS/NZS 2280 i.e. Minimum tensile strength of 420 MPa
and Minimum elongation of 10%. The certification from MPA NRW confirms conformity to
the relevant EN standards; i.e. EN 545 and EN 598.

vonRoll have been manufacturing centrifugally cast iron pipes since 1925. In 1965 the pipe
material changed from grey cast iron to ductile iron and in the early 1970’s the internal
coating was changed to polyurethane.
vonRoll have supplied approximately 60-70% of all pipe in Switzerland, most of which has
been lined with polyurethane since its introduction. Zürich Water has been a major user and
was involved in the initial development of the polyurethane lining and they have been
monitoring the pipe’s performance since that time. They have exhumed some early
polyurethane coated installations and the coating was reported as being as good as when it
was installed.

APPENDIX G – MPA NRW AUDIT OUTCOME AT VONROLL’S
MANUFACTURING PLANT
a) Manufacturing plants: vonRoll casting sa, Choindez, CH-2830 Courrendlin, Switzerland
b) Scope of the audit: The scope of the audit is defined in line with the requirements in
DIN EN 545 and DVGW GW 337-P, and covers ductile cast iron pipes for water pipelines
designed for conducting drinking water.
c) During the audit: The production facilities were inspected, and mechanical values were
determined in the materials laboratory from reference samples. The officer examined the
microstructure on random samples under a light-optical microscope. In the selected
samples (13 embedded samples from between 14.04.2014, 9:40 and 15.04.2014, 11:50),
the officer found a completely pearlitic microstructure with nodular graphite. The officer
also took measurements on random product samples in the finished parts store.
The audit covered the following:
•
Basic requirements for the plant production control system
•
Continuous monitoring of production
•
Recording and documentation
•
Material mechanical characteristic values from reference samples
•
Dimension check on pipes (DIN EN 545)
•
Coating thickness testing on pipe coating
External coating thickness from 10 measured values: Average coating thickness > 70 µm;
Minimum coating thickness > 50 µm
Internal lining thickness from 10 measured values: DN 80 - DN 300 > 1.3 mm; DN 350 - DN
600 > 1.5 mm; DN 700 > 1.5 mm
d) Outcome of the audit: In conclusion, it has been found that the certificate holder vonRoll
hydro (suisse) ag in Oensingen (Switzerland) has the necessary measures in place in
terms of staff, production and testing, as well as a plant production control system, in
order to ensure that ductile cast iron pipes can be manufactured in accordance with the
requirements.
e) Results of the independent audit: The vonRoll hydro (suisse) ag manufacturing plant
in Oensingen (Switzerland) and its production facility, vonRoll casting sa, in Courrendlin
(Switzerland) have the necessary measures in place in terms of staff, production and
testing, as well as a plant production control system, in order to ensure that ductile cast
iron pipes for water pipelines can be manufactured in accordance with DIN 545 and
DVGW GW 337-P.
