For installations where predictable temperature variations occur, the average
material temperature shall be determined from – Item (a) or Item (b) as follows:
a) Across the wall of the pipe – the material temperature taken as the mean
of the internal and external pipe surface temperatures, where a temperature
differential exists between the fluid in the pipe and the external environmental. The pressure and temperature condition, where flow is stopped for
prolonged periods, shall also be checked. In this event, fluid temperature
and outside temperature may equalise.
b) With respect to time – the average temperature may be considered as the
weighted average of temperatures for the proportion of time spent at each
temperature under operational pressures.

The maximum measured mean wall temperature recorded is 35˚C on the top
of the pipe during summer. Site specific conditions may influence and alter this
reduction over black pipe which therefore Vinidex can not offer design guidelines.
Further reference should be sought from the design guidelines in the draft
revision of AS 2033.

Calculated temperature statistics with depth for the central Goldfields.
The majority of the thermal benefits of soil cover in insulating a PE pipeline are
therefore obtained in the first few hundred millimetres of cover with negligible
increase in insulation benefit below this depth.

The pressure rating of PE pressure pipe shall be based on the temperature
of the pipe wall, which may be determined from either:
a) an assumption of a constant pipe wall temperature typical for continuous
service at a set temperature e.g. cold water service; or
b) the determination of an average service temperature where temperature
variations are likely to occur in a predictable pattern eg. in cavity walls of
roof spaces; or
c) the maximum service temperature less 10°C for installations where large
unpredictable temperature variations occur up to a maximum of 80°C
e.g. above-ground installations such as irrigation systems.
For Items (a) (b) and (c), the MAOP shall be in accordance with values in the
above tables.
NOTE:
(i) The values tabled are for materials typically used in Australia/New Zealand.
(ii) The times given in years as (36y) are allowable extrapolation limits obtained
by applying the factors in Table 1 of ISO 9080 to two years of test
data at 80°C. Where appropriate, specific advice should be obtained from the
manufacturer, and data provided shall be derived from testing to ISO 9080.

compressed air systems
working pressure – PE 100
The following tables list maximum operating pressures in kPa. Under these
conditions, the system life is expected to be in excess of 50 years.
For continuous operation at temperatures above 40˚C, life expectancy may
be reduced. However, for normal operation, i.e. variable operating temperatures,
system life would not be reduced, including operation for limited periods at
temperatures up to 60˚C. Specific design data may be obtained from Vinidex.
System pressure capabilities have been derived using a safety factor of 2.
The energy stored in compressed air and have the potential for pressure spikes
means that the pressure rating is less than that for water, for which the safety
factor is 1.25.

NOTE: Polyethylene pipe over PN6.3 can cope with full vacuum. Vacuum is
described as zero pressure (minus one atmosphere).
The negative pressure has been calculated based upon immersion in water at
30˚C wall temperature. The pipe is assumed to have a 3% ovality.
As polyethylene is less dense than water, the pipe will float on the water surface.
The end of the pipe should therefore be inverted to ensure the suction pipe is

Technical Data

Polyethylene flange connections
Polyethylene stub flanges and backing rings are commonly used for connection
to valves and pipe fittings. When designed and installed correctly they have
proven to be a reliable jointing system which can be rated to the full pipeline
pressure rating.
Stub Flange Specification
The stub flange is butt welded to the pipe, hence it is important its wall thickness
is the same as the pipe. It is therefore specified with the same PN and PE rating
as the pipe.
Care should be taken when connecting onto wafer style butterfly valves with
stub flanges. On some valves the mouth of the stub must be machined out
slightly to allow full rotation of the butterfly plate when fully assembled. Where
excessive material must be removed polyethylene tapered spacers must be used
between the stub flange and the valve body.
Backing Ring Specification
Corrosion Protection
Flanges and fasteners should be plated in accordance with Australian standards
or codes such as AS/NZS 4680 for galvanising. Alternatively, stainless steel
flanges and fasteners can be used or flanges can be protected with polymeric
coatings in accordance with AS/NZS 4158 and be used in conjunction with
stainless steel fasteners.
Marking
Flanges should be permanently and legibly marked with the flange designation
and the manufacturers name, either on the rim or on the back of the flange
between the rim and the pitch circle diameter.
Temperature Derating
For continuous operation at temperatures above 20° C, specific design data
should be obtained from the pipe and fitting manufacturers.
Gaskets
The gasket material shall be suitable for the flange, the fluid and the environment.
For specific requirements contact the manufacturer. For flanged joints intended
for use with potable water the gasket material must comply with AS/NZS 4020.
Seals
Natural rubber is generally resistant to most moderate chemicals wet or dry,
Organic Acids, alcohols, Ketones and Aldehydes. It is generally not suitable for
Ozone, Strong Acids, Fats, Oils, Greases,and most Hydrocarbons.
Ethylene Propylene Diene Monomer (EPDM) is generally resistant to Animal &
Vegetable Oils, Ozone, Strong & Oxidising Chemicals. It is generally not resistant
to Mineral Oils & Solvents, Aromatic Hydrocarbons.
Note: The pressure ratings of AS2129 cannot automatically be applied to PE stubs.
29
Polyethylene flange connections
Stub flange and backing ring installation
Flanges must be installed correctly to ensure damage does not occur during
operation. Incorrect installation is the most common cause of flange joint failure.
To avoid this, the following procedure should be used:
1. The flange should be assembled to the mating flange prior to welding the
stub flange to the pipeline. If this is not practical the pipeline should be
snaked a sufficient distance from the joint to ensure the stub can be brought
squarely up to the mating flange.
2. The flange assembly must be lifted AT THE PIPE and BROUGHT SQUARELY
UP TO TOUCH the mating flange PRIOR to bolting. Bringing the flanges into
contact with the mating flange using the bolts will usually result in breakage
of the stub during operation.
3. With the seal lined up, insert all bolts and tighten them until firm taking
care not to damage the seal. Washers should be used under all bolt heads
and nuts.
4. Tighten the bolts in the following sequence to the following torques.
These torques apply for pressures up to 1000 kPa.

heavy haulage road pipe crossings
Unlike concrete pipe, polyethylene’s deflection transfers vertical soil and wheel
loadings into the side fill. This deflection characteristic has proven to support
the pipe under 30m of tailings dam fill quite successfully for many years.
The deflection of cement lined pipe is limited by the flexibility of the cement lining.
The design of a polyethylene pipe under soil and wheel loadings is specified in
AS/NZS 2566.1 Buried Flexible Pipelines.
The performance of a flexible plastic under soil and wheel loadings will depend
upon the following:
n
Pipe Stiffness
n
Soil Strength, Stiffness & Density
n
Superimposed Wheel Loadings
n
Trench Geometry
The pipe performance is particularly sensitive to soil strengths and levels of
compaction.
Bedding material must consist of well graded particles in accordance with
AS/NZS 2566.1.
Side support and pipe overlay material should be placed in nominal 80mm layers
for pipe less than 250mm diameter and in nominal 150mm layers for pipe above
250mm diameter. Material compaction shall be completed as specified in
accordance with design assumptions (AS/NZS 2566.1 details material types,
density and resulting strengths). During placing, care must be taken to ensure
adequate compaction of the material at the pipe haunches prior to placing
overlay material.
The testing of compacted material density shall be completed in accordance
with AS1289 5.1.1.
34
light vehicle road pipe crossings
Whilst Vinidex strongly recommends adherence to the Australian Standard
AS2033 which recommends a minimum cover of 750mm for unsealed roads we
also recognise that pipe crossings under light vehicle roads are frequently laid
with a minimum of cover. If insufficient cover is provided the wheels may inpose
directly onto the pipe resulting in localised buckling, of the pipe.
To avoid this buckling the wheel loadings must be distributed over the pipe. This
may be achieved by applying a 250mm thick layer of compacted pavement over
the pipe after thorough compaction of the side fill in layers to support the pipe.
A common method of achieving this compacted pavement is to use cement
stabilized soil. This involves mixing a proportion of 2.5 bags of cement to one
cubic metre of sand and compacting the mix in layers not thicker than 80mm for
pipes less than 250mm and 150mm layers for pipe 250mm diameter and above.
The moisture content of the mixture shall be only sufficient to enable adequate
mixing and placement of the material. Compact each layer with a minimum of
four passes of a vibratory plate compactor which has a minimum static mass of
50 kilogram. Continue compaction to 95% of the Standard Maximum Dry Density
of the material in accordance with AS1289.
35
allowable bending radius
Vinidex PE pipes are flexible in behaviour, and can be readily bent in the field.
In general terms, a minimum bending radius of 33 x outside diameter of the
pipe (33 x DN) can be adopted for PE100 material pipes, whilst a radius of 20 x
outside diameter of the pipe (20D) can be adopted for PE63, and PE80B material
pipes during installation.
This flexibility enables PE pipes to accommodate uneven site conditions, and,
by reducing the number of bends required, cuts down total job costs. For certain
situations, the designer may wish to evaluate the resistance to kinking or the
minimum bending radius arising from strain limitation. The long term strain
from all sources should not exceed 0.04 (4%).
When bending pipes there are two control conditions:
1. Kinking in pipes with high SDR ratios.

Note: These formulae do not incorporate any factor of safety. Kinking may
occur suddenly and catastrophically and conservatism is advised. Care should be
taken when bending pipes to ensure that the loading and support configuration
produces the mode of bending and the radius of curvature expected.

pipe striping and co-extruded jackets
Vinidex manufactures polyethylene pipe which can be colour striped or
co-extruded with a jacket. This is for identification purposes.
Colour is determined by relevant Australian/New Zealand and/or industry
standards.
White co-extruded for pipe wall heat reduction is also available. Non-standard
colours can be discussed with your local Vinidex office.
Typical stripe colour:
Blue – typically used for general pressure applications and is also used for
compressed air applications.
Yellow – Fuel gases, process gases, liquified gases under pressure.
Purple – Drain Waste and Vent (DWV).
Typical jacket colour:
Yellow – Fuel gases, process gases, liquified gases under pressure.
Purple – Drain Waste and Vent (DWV).

cross-linked polyethylene
in pipeline applications
Abstract:
Cross-linked polyethylene (PE-X) is a material that has been in use for more than
forty years in hot and cold plumbing and cable jacket applications, its resistance
to high temperatures being utilized. More recently, other attributes, including
resistance to slow crack growth (SCG) and rapid crack propagation (RCP) have
facilitated development of PE-X for water, gas, mining and industrial applications.
Cross-linked Polyethylene – What Is It?
Polyethylene consists of long chain molecules which are attracted through
weak forces, known as van derWaal’s forces. The process of cross-linking sees
adjacent molecular chains joined by strong covalent bonds at various positions.
The result is a cross-linked three dimensional lattice, brought about by the
fusion of amorphous and crystalline regions in the polyethylene.
Solid state polyethylene typically consists of amorphous and crystalline regions.
The network resulting from the cross-linking process improves the mechanical
performance of the material, resulting in significant increases in properties such
as: thermal performance, slow crack growth, rapid crack propagation, impact
resistance, tensile strength and abrasion resistance.
The inherent properties of cross-linked polyethylene are leading to exciting
applications in water, gas, mining and industrial applications.

Jointing – Mechanical, Electrofusion, Butt Fusion
As for polyethylene, mechanical and electrofusion fittings may be used for
jointing. Butt fusion, however can only be used under certain criteria – prior to
the polyethylene becoming cross linked or fusing standard polyethylene and
fittings to cross linked pipe. Electrofusion is a suitable Jointing technique
– PE100 couplings have shown to be successfully connect PE-X pipes, but
where elevated temperature (>45oC) and long life (>50 years), other means of
connection, such as mechanical fittings or Plasson PE-X electrofusion fittings,
are required.
Further Jointing arrangements are currently under development.
Application – Mining, Oil and Gas
For the transport of abrasive slurries and fluids at elevated temperature, the
outstanding abrasion resistance of PE-X makes it superior to PE, the usual
material of choice, for this application.
PE-X may also be used a liner for steel pipes used for high pressure slurries,
oil and gas pipelines. For high pressure oil and gas, PE and PA (nylon) have
commonly been used, the latter due to the limited life of PE in these elevated
temperature applications. The use of PE-X overcomes the limitations of PA and
enables a more economic installation.
Availability
Cross linked polyethylene pipe is manufactured especially for each project
therefore consultation with your local Vinidex representative or office is required.

Bore Casing
Contents Page
bore casing / pressure pipe (scj)
PVC pressure pipe is designed and used primarily to contain liquids under
internal pressure – hence the classification system is based on pressure class
designations. PVC pressure pipe is also legitimately used for other applications
such as water bore casings. In this application, PVC pressure pipe is used to
form the outside casing of a water bore drilled vertically down into the ground
where the loads on the pipe are primarily external.
Historically, PVC-U has been successfully used as casing pipe but with the arrival
of PVC-M and PVC-O there is a potential for inappropriate use of pipe because
they may be in equivalent pressure classes (i.e. all PN12). If a pipe supplier is
asked for a PVC-U PN12 pipe under most circumstances a PVC-M or PVC-O PN12
pipe can be substituted but not for bore casing applications. The key property
of the pipe relevant to this application is stiffness and this is essentially a direct
relationship to the pipe wall thickness, regardless of the PVC material type.
The reference document for water drilling contractors is the Minimum Construction
Requirements for Water Bores in Australia (MCR) which specifies that all PVC
bore casing pipe shall be PVC-U to AS1477 with the minimum casing diameter of
100mm. Hence this could be either Series 1 or Series 2 pipe. The actual size of
the casing pipe is determined by the pump diameter and will be specified by the
purchaser. The MCR nominates PN9 as the minimum pressure class to use for
shallow low yield bores, and nominates PN12 pipe in all other cases.

Temperature Considerations
Supermain™ pipes are de-rated for temperature according to the International
practice for PVC based pipe materials as shown in the below table. Supermain™
pipes can be used for continuous service at temperatures up to 45°C. Higher
temperatures should be avoided as Supermain ™will experience ‘reversion’ of
the oriented structure at elevated temperatures, and may undergo significant
dimensional distortion above 50°C.
The operating temperature above refers to the average across the wall. Short
term exposure on one surface to temperatures in excess of the maximum
operating temperature, such as may occur during storage can be tolerated.
If extreme conditions are encountered for extended periods during pipe storage,
some ovality may develop in the pipe or socket. This is of no consequence in the
performance of the product and for jointing, Supermain pipes are readily
re-rounded in making the joint.
If prolonged storage is expected, consideration should be given to shading the
pipe with a material such as shade cloth or hessian, which does not concentrate
the heat, placed so as to not restrict the circulation of air in the pipes, which has
a cooling effect.

Fatigue Design
Where a pipeline is to be subjected to a large number of cyclic or repetitive
loads, fatigue design must be considered. For Supermain™ pipes, de-rating may
be required if the total number of cycles in the pipe lifetime exceeds 30 000.
Lateral Loadings and Negative Pressures
The stiffness (lateral load for a given diametral deflection) is related to material
modulus and the cube of the thickness. For PVC-O materials, the modulus is
somewhat higher than that for standard PVC-U. However, the wall thickness is
the overriding factor in determining the stiffness. Supermain™ pipes have a
significantly lower stiffness than standard PVC-U pipes of the same pressure
class. This is important in determining the response to lateral loading, due to
soil and traffic, and negative pressures due to vacuum, ground water etc. In
general water supply works with buried pipes at normal covers, lateral stiffness
will not be a limiting design factor and will not require special consideration. For
abnormal conditions, design should be conducted in accordance with AS/NZS
2566. Vinidex recommends the following values be used for the ring bending
modulus for Supermain™ pipes:
Short Term Ring Bending Modulus at 20°C Eb 4000 MPa
Long Term Ring Bending Modulus at 20°C EbL 1800 MPa
Buckling may result if the pipe is subjected to internal vacuum, as a result of
water hammer or siphonage. Other special cases include pump suction lines
(with or without submersion) and concrete encasement.
70
supermain™ pvc-o
Installation
Installation techniques for Supermain™ pipes are similar to that used for
standard PVC-U pipes. The lower wall thickness and stiffness of PVC-O pipes
compared to PVC-U pipes makes it essential that recommended practices for
installation are adhered to and the pipe is fully supported.
Quality non cohesive material should be used for pipe bedding, side support and
overlay. The pipe side support material should be placed evenly on both sides
of the pipeline to two thirds the height of the pipe diameter and compacted by
hand tamping. Side fill material should be worked under the sides of the pipe
to eliminate all voids and provide maximum pipe haunching. The pipe overlay
material should be levelled and compacted in layers to a minimum height of
150mm above the crown of the pipe or as specified.
The field testing procedures specified in AS2032 and the Vinidex Water Supply
Manual should also be followed for Supermain™ pipelines except that the field
test pressure should not exceed 1.25 times the pressure rating of the pipe.
Jointing
Supermain™ pipes are supplied with integral sockets for rubber ring jointing.
The integral joints are capable of 1° deflection. Further deflection can be
achieved using deflection couplings. Solvent cements should not be used with
Supermain™ pipes.
Fittings
A complete range of pipeline fittings is available for Supermain™ pipes to form a
total pipeline system.
Jointing to Ductile Iron Fittings
Supermain™ pipes may be jointed to ductile iron push fit and compression
gasketed fittings. As with standard PVC-U, factory witness marks are not
applicable when jointing to ductile iron fittings, and the spigots should be fully
inserted to the stop. It is advisable before jointing to mark a witness line on the
spigot at the appropriate length for the particular fitting so that full insertion can
be observed.
71

Service Connections
Service connections to Supermain pipes are made using a suitable tapping band
complying with AS/NZS 4793 (Int) – Mechanical tapping bands for waterworks
purposes and the following considerations:
n
n
Holes should be drilled using a hole saw.
Tapping bands having full circle support, an “O” or “V” seal, and
positive stop against over-tightening are recommended for PVC-O pipes.
Vinidex does not recommend direct tapping of any PVC pipes, including
Supermain™.

Ductile Iron Fittings
Superlink™, Irrigation Bases, Hawle-A Valves.
Deep Sockets
The opportunity for socket withdrawal relies on a number of factors, chamfer
length, squareness cut of pipe end, contraction due to temperature differential,
poisson contraction of pipe when pressurised and how well the pipeline is
constructed. There is much debate in the industry as to the appropriate value of
each of these parameters, so the best way to insure against withdrawal is to use
the biggest entry fittings available.
The Vinidex Superlink™ range has the deepest socket entry available
in Australia, they are suitable for all pipe materials in all classes: Supermain™
PVC-O, Hydro™ PVC-M, modified PVC, PVC or ductile iron.

PVC pipes are lightweight and easy to handle and install. This section outlines
the procedures for all aspects of below and above ground installation of PVC
water supply pipe systems. Reference should also be made to AS 2032 –
“Installation of PVC-U pipe systems”.
A number of water authorities require pipelayers to have participated in a
training programme. The “Plastek” PVC Pipe installation programme, which
was developed by TAFE and major water authorities in conjunction with Vinidex,
is available through many TAFE colleges around Australia.
Cutting
During manufacture pipes are cut to standard length by cut-off saws. These
saws have carbide-tipped circular blades which produce a neat cut without burrs.
However, pipes may be cut on site with a variety of cutting tools. These are:
1. Proprietary cutting tools.
These tools can cut, deburr and chamfer the pipe in one operation.
They are the best tools for cutting pipe.
2. A portable electric circular saw with cut-off wheel.
This is quick and easy to use and produces a neat clean cut requiring little
deburring. It does, however, require a power supply and the operator has
to be skilled in using it to produce a square cut.
3. A hand saw and mitre box.
This saw produces a square cut but requires more deburring. It takes
comparatively more time and effort and requires a stand. The use of roller
cutters is not recommended.
Solvent Cement Joints
Vinidex recommends Vinidex solvent cements and priming fluid for use with
Vinidex PVC pipes and fittings, thus ensuring a complete quality system. Vinidex
premium solvent cements and priming fluid are specially formulated for PVC
pipes and fittings and should not be used with other thermoplastic materials.
The following procedure should be strictly observed for best results. The steps
and precautions will allow easy and efficient assembly of joints. Users may refer
to AS/NZS 2032-1977 Code of practice for installation of PVC pipe systems for
further guidance.
Incorrect procedure and short cuts will lead to poor quality joints and possible
system failure.
76
Solvent Cement Jointing Principles
Sockets on Vinidex pressure pipes and fittings for solvent cement joining are
tapered, ensuring the right level of interference. This may not apply to all pipes
and fittings, particularly from other countries.
Vinidex offers two types of solvent cements formulated specifically for pressure
and non-pressure applications. They are colour coded, along with the primer, in
accordance with AS/NZS 3879:
n
n
n
Type ‘P’ for pressure, including potable water installations, designed
to develop high shear strengths with an interference fit (green solvent,
green print & lid).
Type ‘N’ for non-pressure applications, designed for the higher gap
filling properties needed for clearance fits (blue solvent, blue label & lid).
Priming fluid for use with both solvent cements (red priming fluid,
red label & lid).
Always use the correct solvent cement for the application. Solvent cement
jointing is a ‘chemical welding’, not a gluing process. The priming fluid cleans,
decreases and removes the glazed surface thus preparing and softening the
surface of the pipe so that the solvent cement bonds the PVC.
The solvent cement softens, swells and dissolves the spigot and socket surfaces.
These surfaces form a bond into one solid material as they cure.

jointing methods for pvc – rubber ring
Rubber Ring Joints
Jointing rings are supplied with the pipe, together with a lubricant suitable for
the purpose. Other lubricants may not be suitable for potable water contact and
may affect the ring. They should not be substituted without specific knowledge
of these effects.
The ring provides a fluid seal in the socket of a pipe or fitting and is compressed
when the spigot is passed into the socket. Check the label on the pipe socket.
Series 1, Series 2, sewer rings or rings from other manufacturers cannot be
interchanged. Sewer rings contain a root inhibitor and must not be used for
potable water lines. These rings can be easily identified by their two coloured
dots, pressure rings have only one coloured dot.
Chamfering
Vinidex PVC pipes for rubber ring jointing are supplied with a chamfered end.
However, if a pipe which has been cut in the field is to be used for making a
rubber ring joint, the spigot end must be chamfered. Special chamfering tools
are available for this purpose, but in the absence of this equipment a body file
can be used provided it does not leave any sharp edges which may cut the
rubber ring. Do not make an excessively sharp edge at the rim of the bore and
do not chip or break this edge. As a
guide to the correct chamfer, the

When a pipe is cut, a witness mark
should be pencilled in and care should
be taken to mark the correct position
in accordance with Table 4.1.
Where two witness mark positions are
given, both should be marked on the
pipe and the joint made so that one
mark remains visible
