Joining
The Wavisafe "Z-LOK" joint is integrally moulded on The seal ring's ribbed profile reduces friction during
one end of the pipe. The joint incorporates a factory assembly.
fitted rubber sealing ring which is retained in position
by a polypropylene lock ring. Each joint is capable of
handling some expansion and contraction as well as
angular deflection. The seal ring is designed to
provide a watertight joint at high and low pressures.
Each length of pipe has a "depth of entry" mark on
the spigot end to ensure correct installation.
Rubber seal, firmly fixed into the correct position
with a polypropylene lock ring. This prevents
accidental displacement of the seal ring during
jointing. Factory assembly ensures that the
supplied joint is fully functional. No more concern
about joint failure due to the use of randomly
sized or incorrectly placed seals.

SG Iron Reducers
There are two types of reducers available, namely socketed both sides and spigot and socket.
Both are used for in –line reduction of pipe size. However, the spigot/ socket reducer has an
advantage when used in conjunction with a fitting. The spigot end can be fitted into any of the
sockets on these fittings.

Physical properties
Polyvinyl Chloride (PVC) is a thermoplastic material
which consists of a PVC resin compounded with
varying proportion of stabilisers, lubricants, fillers,
pigments, plasticizers and processing aids. Different
formulations of these ingredients are used to obtain
specific properties fro different applicants. Pipes can
therefore be developed to meet the requirements of a
wide variety of applications and conditions.
General
The general properties given in the table below are
those for PVC compound formulations used in pipe
manufacture. It should be used noted that these
properties are relative to temperature and the
duration of stress application.

The stress Regression Line
The traditional method of portraying the primary mechanical property of PVC, tensile strength, is by
means of a graph of log stress vs. Log time to failure. This is known as the stress regression line. It is a plot
of the circumferential hoop stress in the wall of the pipe (from internal pressure) against time to failure.
Numerous actual test results, measured at 20 0C and 600 C, over a range of times up to 10,000 hours,
are plotted on a log scale and a regression line is calculated to fit this data. The resultant regression line is
then extrapolated to 50 years (438,000 hours). The method of calculation is an internationally accepted
procedure described in ISO/TR 9080. The required values of stress and time are specified in SANS 966
parts 1 and 2.
The method for calculating circumferential hoop stress is derived from Barlows formula and is as follows:A = p (d-t)/2t
Where
Q = hoop stress in wall of pipe (MPa)
P = Internal pressure (MPa)
17
Design stress and safety factor (service
factor)
As can be seen from the stress regression lines,
the creep rapture strength diminishes with

have been adopted. These factors have resulted in
the given design stresses being applicable. The Expansion and Contraction
design stress is derived by dividing the 50 year hoop All plastics have high coefficients of expansion and
stress ( MPa- from the stress regression line) by the contraction, several times that of metals. This must
be allowed for in any installation by the use of

Effect Of Temperature Change
Working pressure
The standard design temperature for PVC pipes is 20
ºC and working pressure are usually quoted for this
temperature. PVC pressure pipes function perfectly
well below 20 C, right down to freezing point, and can
in fact withstand higher pressures than those quoted
at 20 ºC.

Chemical Resistance
Lamasat PVC pipes and fittings are highly resistant to acids, sewage of the most aggressive soils. Alkalis
have very effect on PVC. The table below summaries this resistance but further information can be

Design Considerations
In SANS 966 there are 7 different pressure classes ( see page 41). These classes include suitable safety
factors and are intended as a guide to trouble free operation under average service conditions. There are
however many factors which must be considered when determining the severity of service and the
appropriate class of pipe. This section is provided as a guide to the designer in the light of his or her
knowledge of the particular circumstances.
Amongst the factors to be considered are:
· Operating pressure characteristics
· Static conditions
Dynamic conditions
Water hammer
· Cyclic loads
Temperature
· Effect of pressure
· Effect on dimensions
· Trench load conditions
· Soil loads
· Traffic loads
· Bending
· Thrust support
· Flow considerations
· Selection of pipe size and class
Pressure Considerations
Static Pressure
The hydrostatic pressure capacity of PVC pipe is
related to a number of variables:
P = 2 x t x Q /d
The ratio between the outside diameter and the wall

T = P x d /(2Q + p)

t = minimum wall thickness (mm)
 The operating temperature

 The duration and variability of the stress applied by
q = circumferential hoop stress ( MPa)
the internal hydrostatic pressure.
Although PVC pipe can withstand short- term
hydrostatic pressure at levels substantially higher
than the pressure rating, or class, ( see “ The stress
Regression line” and “ Design Stress and safety
factor” earlier) the duty of PVC pipe should always be
based on the pipes long – term strength at 20 ºC to
ensure a design life of at least 50 year. As stated
earlier, line relationship between the internal
pressure, the diameter and wall thickness and the
circumstantial hoop streets in the pipe wall, is given by
the Barlow Formula, which can also be expressed as
follows
These formula have been standardized for use in
design, testing and research and are applicable at all
levels of pressure and stress.
For design purposes, p is taken as the maximum
allowable working pressure and q, the maximum
allowable hoop stress at 20 ºC.
The design hoop stresses used in SANS 966 are as

It stress peaks in excess of the design stresses are

occur earlier. For this reason peak pressures should not be
allowed to exceed maximum recommended working
pressures.

Since part of the formula for calculating wave

crack initiates from some dislocation in the material matrix, and wall thickness ( SDR), which is roughly
usually towards the inside surface of the pipe where stress constant for all sizes within a pressure class, the

Therefore a pipe subjected to a pressure cycle of zero to
half working pressure is as much in danger of fatigue as
one subjected to a pressure cycle of half to full working
pressure. Thus pipe fatigue failures occur just as
frequently at high points in the system as at low points
where the total pressure is greater.
WATER HARMMER
Pipelines may be subjected to short-term increase in
pressure above the normal working pressure due to
water hammer. Water hammer will occur in a pipeline
when its equilibrium is disturbed by rapid changes
It is important to note that the pressure increase due
to water hammer in a particular class of pipe is a
function of the change in velocity and it is therefore
important ( for this and other reasons) to keep
pumping velocities in a pipeline within the
conventional norm of 1 to 2 m/s.
In general steps should be taken during design and
operation to minimize the frequency and intensity of
water hammer. However the total pressure may be
permitted to reach a value 50% higher than the normal
pressure if the frequency can be described as “
occasional.”
21
Cyclic loads
A design for fatigue must involve:
1. An estimate of the magnitude of pressure
fluctuations likely to occur in the pipeline, i.e the
difference.
2. An estimate of the frequency, usually expressed as
cycles per day, at which such fluctuations will occur.
3.A statement of the required service life needed from
the pipe.
The design can be done on the basis of the
Temperature considerations
Effect on pressure
The pressure classes of PVC pipes carrying the
SANS 966 mark have been allocated on the basis
of design at 20 ˚C. Any pipes used in applications
where operating temperatures exceed 25 ˚C need
to be de-rated to ensure that the 50 year design life,
or the safety factor, is not adversely affected. The
following pressure reduction factors should be applied.

established relationship between pressure amplitude
and the number of cycles to failure. This relationship

including all transients, both positive and negative.
Alert:
The maximum recommended working temperature
is 60˚C
At lower temperatures, between 20˚C and 0 ˚C, the
pressure handling capability does increase but it is
recommended that this be ignored. If water freezers
inside PVC pipe permanent strain (if not fracture) may
occur, leading to a possible severe reduction in the
working life of the pipe.
Effect on Dimensions
Due to the relatively high coefficient of expansion and
contraction (given in “Expansion and contraction” earlier)
it is necessary to make allowance for this in any design
and installation which is exposed to wide variations of

Assuming that half the well capacity is utilised, then
the average switching rate will be 21 cycles/day.
Assuming is no significant water hammer, the
dynamic range is 35 metres. According to the chart a

22
Ultraviolet Light Considerations
The vast majority of PVC pressure pipes are intended
for burial in trenches and they are therefore
manufactured with relatively low levels of additives to
protect them against the effects of ultraviolet light.
Pipes which will be exposed indefinitely to UV light
should be protected by painting with a coat of light
coloured AIkyd Enamel or PVA.
Paint containing solvent thinners should be avoided.
It is recommended that pipes should be buried
wherever possible.
Trench Load Considerations
It has been well established by researchers over
many years that, for flexible pipes, it is the interaction
between the soil and the pipe which has to be
considered more extensively than is the case for rigid
pipes where the material strength of the pipe is the
critical issue. The points discussed here are given as
a guide only to aid design by the engineer.
Soil And Traffic Loads
The vertical load on a PVC pipe due to soil is a function
of the trench width and depth, the until weight and type
of the soil and the pipe diameter and wall thickness. This
loading must generally be corrected because of the fact
that the soil is cohesive and the side fill reacts with the fill
above the pipe. Furthermore flexible pipes deflect and
shed load to the side fill. This vertical deflection is limited
by lateral soil resistance. The resultant load is therefore
less than that which Colum theory suggests.
The soil loading graphs below that, after initial rapid
increases with increased depth, this rate of increase
falls away to almost zero at depths of about 6 metres or
more. Typical maximum values of soil loads ( without
live loads) are between 1000 and 17000 N/m ( for sizes
between 50 and 500mm).
depending largely on soil type, modulus and pipe
stiffness. As soil compaction is increased so the
maximum soil load on the pipe reduced, assuming
that backfilling procedures have been followed.
Soil load at shallow depths increases dramatically when a
60 KN live load is added. This effect is aggravated by poor
compaction. However, from about 3 metres deep this
effect becomes negligible. As can be seen from the
deflection vs. Soil load graph there is a straight line
relationship between deflection and soil load for each size
and class of pipe. Therefore if the soil load reaches a
maximum . these graphs then the deflection also has a
maximum. These graphs include the maximum soil loads
from the soil load graphs include the maximum soil loads
from
the soil load graphs and shows the maximum
deflection ( for the conditions represented) of less than
1.8% - for a 500 mm class 6 pipe – even with a 60 KN live
load. Large diameter pipes carry more load because of
their greater surface area. Thicker pipes carry more soil
load because it is more difficult to deflect since less load
shedding occurs.
The graphs below were based on calculations using
values typical for reasonable backfill material which has
been poorly compacted ( soil modules of 3 MPa) excluding
and including a 60 KN live load. Trench widths of 0.4m,
0.6m, 0.7m and 0.8m were used for the following groups of
pipe sizes 50mm – 160mm, 200mm – 315mm, 400mm
and 500mm. Different soil cover the pipes were used,
varying from 0.9m to 10m. The method of calculation was
provided by Professor David Stephenson of
Witwatersrand University.
We have shown graphs on the following pages for class 6
and class 16 only but have available graphs for class 9 and
class 12 which show very similar trends. The graphs
represent Aqua-Wall mPVC pipes.

How to read these charts
· Choose the particular chart for the type (uPVC or mPVC) and class of pip being used.
· In one of the first three columns find the nearest value of the quantity of water to be pumped
according to the proffered unit of measurement.
· GPH = Gallons per hour
· M/hr = Cubic meters per hour
· I/s = Litres per second.
· Align the selected reading horizontally to the light green shaded values. The value in the
shaded block is the friction loss ( expressed in meters per 100 metres) for the size of pipe
given at the top of that particular column.
· The reverse sequence can be used to determine the amount of water that can be pumped
through a given pipe size ( and how much friction loss is created.

Installation And Use
When glueing the connector of the pipe, care must
be taken to prevent the glue or solvent from coming
in contact with the valve seats or ball. Threaded
ends should not be connected with cone-shaped
male threads and the use of hemp or similar
materials should be carefully avoided. A special
attention should be paid to the correct line-up of the
installation and to the pipe length using Z distance.
Tighten the union nut hand tight only. The use of
wrench is not allowed. it is important that unions are
not used to pull the system together. If there is
leakage from the union nuts, please check the
correct line-up of the system and the pipe length.
An excessive tightening of the unions could finally break
them. Before the valve is cycled, all dirt, sand or other
material should be flushed from the system. This is to
prevent scarring of the ball and/or seats. It is important to
avoid rapid closure/opening of the valve to eliminate the
possibility of water hammer causing damage to the
pipeline. It is necessary that all installation and
maintenance personnel become familiar with the proper
solvent cement and tread joining procedure

Fit for Water
PVC Borehole Casing & Screens
Our u-PVC Casings and screen pipes are manufactured with selected PVC compounds to provide absolute non-corrosive
pipes with excellent mechanical properties. The casing and screens are threaded flush internally and externally to two
standards:
1. DIN 4925
2. ASTM F480-88 2 Tpi
Lengths are standard 3m to 6m or customised according to the client specifications.
Advantanges;
Corrosion: the chemical inertness of uPVC makes them insensitive to all forms of corrosion, thus making them excellent
products for use in Acid Mine drainage wells or high PH applications
Mechanical properties: excellent resistance to high collapse pressures, together with high tensile loads with the "DIN"
threading.
Accurate slot sizes: with our various slotting machines we are able to produce accurate slot sizes which are consistent
and therefore easily matched up to calculated flow rates which designers can use when designing systems
Cost effective: lower installed cost compared to conventional (steel) casings.
Internally and externally flush jointed: easy installation in borehole and improved flow of pumped water.
High modulus of elasticity: makes for stiffer casings and screens which can be designed for boreholes up to at least
200 m deep.
