JoiningThe Wavisafe "Z-LOK" joint is integrally moulded on one end of the pipe. The joint incorporates a factory 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.

The seal ring's ribbed profile reduces friction during assembly.

Male/Female reducer (spigot and socket)

SG Iron ReducersThere 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 propertiesPolyvinyl 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 LineThe 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)

Design stress and safety factor (service factor)Safety factors take into account handling conditions, service condition and other circumstances not directly considered in the design.

In terms of SANS 966 the following safety factors have been adopted. These factors have resulted in the given design stresses being applicable. The design stress is derived by dividing the 50 year hoop stress ( MPa- from the stress regression line) by the chosen safely factor.

Applying Barlow's formula (below) it is now possible to calculate the minimum wall thickness for any given size and pressure class of pipe.

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

t= minimum wall thickness (mm)WhereP = pressure (Mpa )d= mean external diameter (mm)Q = design stress (MPa)

For example the minimum wall thickness for a 250 mm class 16 uPVC pipe is:

T = 1.6 x 250 / {2 x 12.5) + 1.6}= 15.04 mm ( rounded up to 15.1 mm for manufacture)

As can be seen from the stress regression lines, the creep rapture strength diminishes with increasing temperature and working pressures must be down – rated if the factors of safety are to be maintained. The applicable reduction factors are given under. “temperature Considerations” later.

Expansion and ContractionAll plastics have high coefficients of expansion and contraction, several times that of metals. This must be allowed for in any installation by the use of

The effect of Ultra violet lightMost plastics are affected by UV light. PVC pressure pipes have UV l ight stabil isers incorporated in their formulation but if pressure pipes have to be exposed for an indefinite period, they should b painted, preferably with one coat of white Alkyd Enamel or PVA.

Long – term exposure ( more than 4 to 6 months – dependant on climate conditions) to UV lightcan cause discoloration of the pigments in the pipe and, in severe cases, lead to some embrittlement. Such embrittlement affects the ability to withstand impacts but does not reduce pressure handling capabilities.

Effect Of Temperature ChangeWorking pressureThe 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.

Design ConsiderationsIn 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 conditionsWater 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 ConsiderationsStatic PressureThe hydrostatic pressure capacity of PVC pipe is related to a number of variables:The ratio between the outside diameter and the wall thickness ( standard dimension ratio) They hydrostatic design stress of the PVC pipe being used (uPVC or mPVC) The operating temperature The duration and variability of the stress applied by 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

P = 2 x t x Q /d

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

Where: p = internal pressure ( MPa) t = minimum wall thickness (mm) d = mean outside diameter (mm) q = circumferential hoop stress ( MPa)

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 follows:

sizes up to 90 mmPart 1 10 Mpa

Other sizes 12.5 Mpa

All seizesPart 2 18 MPa

Dynamic PressureThe pressure classes of SANS 966 PVC pipes are based

on constant internal pressures. PVC pipes are however

capable of handling dynamic pressure events which

exceed the values given by the classes but such

occurrences can have a negative effect on the normal 50

years life expectancy and in extreme cases can result in

product failure.

PVC pipes are capable of handling accidental events,

such as pressure surges due to a power cut. However, if

repetitive surges are likely to exceed about 100,000

occurrences during a 50 year operating lifetime, which is

equivalent to an average of one surge wave every four

hours for the total life of the pipe, then fatigue is a

possibility and a fatigue design should be carried out. For

most water supply lines this frequency of surges never

occurs.

It stress peaks in excess of the design stresses are

present , fatigue proceeds more rapidly and failure can

occur earlier. For this reason peak pressures should not be

allowed to exceed maximum recommended working

pressures.

Studies of fatigue responses have shown that a fatigue

crack initiates from some dislocation in the material matrix,

usually towards the inside surface of the pipe where stress

levels are highest, and propagates or grows with each

stress cycle at a rate dependent on the magnitude of the

stress. Ultimately the crack will penetrate the pipe wall,

extending from a few millimetres to a few centimetres long

in the axial direction and will produce a leak.

It is important to appreciate that the growth of a fatigue

crack is primarily dependent on the stress cycle amplitude,

i.e the maximum pressure minus the minimum pressure.

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 HARMMERPipelines 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

in flow conditions. Examples of such conditions are: starting and stopping of pumps, rapid opening and closing of valves, pipe failures etc.

A rapid change in the velocity v of water in the pipeline gives rise to a pressure increase p according to the formula : P = C V /gWhere : c = wave celerity ( metres per second) G = acceleration due to gravityThe wave celerity for hydro – wall ( uPVC) and Aqua –wall (mPVC) have been calculated and given below.

NOTE:Since part of the formula for calculating wave celerity incorporate the ratio between diameter and wall thickness ( SDR), which is roughly constant for all sizes within a pressure class, the wave celebrities are also constant for all sizes within a pressure class.By way of comparison the wave celerity for steel pipes is about 3 times higher than for PVC ( 1000 to 1400m/s)

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.”

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 established relationship between pressure amplitude and the number of cycles to failure. This relationship is represented graphically below. The pressure amplitude is defined as the maximum pressure, minus the minimum pressure experienced by the system, including all transients, both positive and negative.

Example A sewer rising main with a static rise of 15 metres and a total pumping head of 50 metres is designed to service a population of 400 growing to 1,000 in 50 years. Through put is 300 litres/head/day average and well capacity is 20,000 litres. Over the life of the scheme the average throughput is 210,000 litres/day. 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 class. 6 pipe is satisfactory.

Temperature considerationsEffect on pressureThe 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.

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 DimensionsDue 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 temperature.

PVC pipes will expand or contract by 0.08 mm per metre per ˚C rise or fall in temperature A 30 ˚C temperature rise will therefore cause a 14.4mm expansion of a 6 metre pipe.

Ultraviolet Light ConsiderationsThe 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 ConsiderationsIt 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 LoadsThe 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 p rov ided by Pro fessor Dav id S tephenson o f 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.

Bending An important feature of PVC pipes is that they may be deliberately bent, within limits, thus eliminating the need, in some cases, for separate bends. As a rule of thumb the radius of such a bend must not be less than 300 times the pipe diameter. In addition each rubber ring joint can accommodate a further ½ of bend. This feature significantly reduces costs and speeds up installation times when compared to some traditional pipe materials.

Thrust supportAn unbalanced thrust is developed by a pipeline at: changes of direction greater than 10˚eg. Tess ad bends

v Changes in pipe sizev Valves and End Caps

In most of cases the soil bearing capacity is insufficient to withstand such forces and it becomes necessary to use thrust blocks if the pipes have rubber ring joints.The size of the bearing area of the thrust block is determined by the bearing capacity of the particular type of soil into which the pipe is installed and by the diameter and operating pressure of the pipeline. When cover is less than 600mm it may be necessary to take further precautions to prevent vertical movement due o thrust . if the pipeline to be pressure tested at a pressure higher than working pressure then thrust block design must allow for this pressure.

The tables below along with the supplied example, provide a guide to determine thrust block sizes

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 UseWhen 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

PVC Borehole Casing & ScreensOur 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 49252. 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.
