Properties and PerformanceStructural and Mechanical PropertiesuPVC Pipes derive their load bearing capacity from a combination of their inherent stiffness and the characteristics of the bedding and sidefill material with which they are used. When a vertical load is imposed on a flexible pipeline it will deform (radial deformation) and the resulting horizontal force is transmitted to the undisturbed trench wall via the sidefill material. A state of equilibrium is reached and any deflection of the pipe ceases when the horizontal reaction of the sidefill corresponds to the transmitted vertical load.
The design of a uPVC pipeline must therefore take into account the interaction between the pipe and the bedding material. This will enable uPVC pipes to withstand imposed loads without excessive deflection whilst also maintaining their ability to cope with possible ground movement without fracturing.
The minimum specific tangential initial stiffness of Marley Twin-wall and solid wall drain pipe is given in Table 1 below.

Minimum Kn/m² 20°C
Twin Wall Pipe 110 8

Solid Wall Pipe 110 6

Table 1: Specific Tangential Initial Stiffness (STIS)
As will be explained on page 29, the correct selection and placing of bedding and backfill materials will prevent the occurrence of an unacceptable level of deformation.
upvc-sewer-n-drainage-sys_v001 uPVC Sewer & Drainage Systems 1�/3�
Chemical PropertiesMarley pipes and fittings are highly resistant to acids/alkalis and thus to aggressive soils. Please see Table 2 below.
Chemical Type PVC Reaction/Suitability
Acids No attack by concentrated or diluted acids at temperatures up to 60°C, except for oxidizing acids such as concentrated nitric which attacks PVC above 20°C. In stressed applications, design stress,at 20°C, should be reduced by: from 2.5% for 10% sulphuric -to 27.5% for concentrated nitric.
Alkalis No attack at temperatures up to 60°C even by concentrated alkalis. However in stressed applications, design stress must be reduced significantly, e.g. by 40 - 50% for 10% sodium hydroxide.
Aromatic hydrocarbons and highly polar organic materials such as ketones, esters, cyclic ethers, nitro-compounds and hydrocarbons.
Not suitable.
Aliphatic hydrocarbons No effect.
Aliphatic alcohols No attack at room temperature but design stress must be reduced by half.
Halogens - chlorine No attack if dry.
Halogens - chlorine Not suitable if moist
Halogens - bromine Not suitable
Halogens - fluorine Not suitable
Halogens - iodine Not suitable
Oxidizing agents Little attack even by the strongest, such as concentrated potassium permanganate, but design stress must be reduced by 25%.
Reducing agents No effect up to 60°C
Detergents No attack

Pipe Flow CharacteristicsMarley underground drainage pipe provides low hydraulic resistance and excellent flow characteristics.
Table 3 below indicates full bore velocities and capacities for Marley Twin Wall and Solid Wall sewer and drainage pipes at various gradients. The values have been derived from the Colebrook White formula using data supplied by the British Hydraulics Research Station.
A minimum self cleansing velocity of 0.76m/s should normally
be adhered to (shaded area), taking into account proportional
velocities for pipe running part full where necessary.
Roughness Height (ks) = 0.6mm (Surface Water Systems).

Design & InstallationAll work should be in accordance with national building regulations and applicable bylaws. Information in this section is intended to highlight and supplement relevant sections of South African National Standards; SANS 10400, SANS 10112, SANS 10252-2 and SANS 1200LD. Consult Appendix A for the SANS title, an abstract and purchase details.
For secure joints, only use pipe and fittings from the Marley
Sewer & Drainage range. When joining, sockets and seals must be
clean and free from swarf or any grit.
SANS 10252-2, section 6.8 details the correct test and
inspection procedure to follow before any work is concealed or
covered. Local authorities may require tests for drains to be
carried out as detailed in SANS 10400 Part P, item PP26.
The efficiency and effectiveness of rodding is dependant
largely on the procedures adopted and the correct choice of
properly maintained rodding tools. Poor practices and/or damaged
or inappropriate rodding tools could damage sewer pipes. It is
advisable to consult a drain cleaning expert to ensure that the
correct methods and equipment are used.
Pipe CuttingPipes are easily cut to length on site using a fine tooth saw and a fabricated mitre box (Fig. 6). Saw cuts should be made square to the pipe. Twin Wall saw cuts should be made midway between corrugations (Fig. 7).Solid Wall pipe ends need to be chamfered after cutting (Fig. 8). Remove all swarf from cut ends.

How to Join Twin Wall
and Solid Wall Pipe to
Marley FittingsThe lip-seal system of joining is simple yet effective. Solid Wall pipes and all spigot ended Marley Sewer & Drainage Fittings have a chamfered edge to assist joint assembly.
Determine the insertion depth mark and transfer this to the pipe using a permanent marker. Follow the same procedure when joining a spigot ended fitting. The insertion depth may be determined by measuring the depth from the fitting’s outside face to maximum insertion depth less a 10mm allowance for pipe movement. See Fig. 19 and 20.Ensure that the rubber seal ring is correctly positioned in the socket recess of the fitting or pipe socket.Apply a small amount of Marley lube to the chamfered spigot end and to the rubber seal ring (Fig. 21 and 22).

Line the pipe (or spigot) end up with the socket and push firmly through the ring seal until the insertion depth mark is level with the face of the socket (Fig. 23 and 24). Where Marley Twin wall pipe is being joined, push until you should feel the lip seal engage a pipe corrugation; stopping just short of the insertion depth mark.

Marley Repair Coupling (Kimberly Socket)The Marley Repair Socket has been designed to permit additional branch connections or repair to an existing Marley soil pipe installation, without causing major and costly alteration.
RepairsYou will need 2 Repair Sockets (UK40) and a section of pipe long enough to repair the damaged section.The first task concerns the accurate marking of the portion of pipe to be cut and removed from the system. Carefully cut away the damaged section with a hacksaw or other fine tooth saw. Cuts should be made square to the pipe axis. Chamfer and deburr the pipe ends. See Fig. 25 and 26.Measure the length of pipe required to repair the damaged section and cut a new section of pipe for this purpose. Cuts should be made square to the pipe axis. Chamfer and deburr the pipe ends. See Fig. 27.Determine the insertion depth mark from the Repair Socket by halving the total socket length (Fig. 28).

Using a black permanent marker, transfer this length onto both ends of the repair pipe section (Fig. 29).Lube the Repair Sockets and all pipe ends.Insert a Kimberley socket to the fullest extent over each end of the repair pipe section (Fig. 30). Alternatively insert a Kimberley socket to the fullest extent over each end of the existing pipe line.The repair pipe section is then inserted into the gap. All that remains to complete the installation is to slide the Kimberley sockets over the ends up to the insertion depth marks. See Fig. 31 and 32.

New branch connectionsFor new branch connections, cut two small sections of pipe long enough to form a spigot ended branch section. Prepare the sections, taking care to chamfer and deburr all pipe ends. Establish the spigot ended branch section. See Fig. 33 and 34.Now measure the piece from spigot end to spigot end (Fig. 35).Transfer this dimension to the existing pipe section and carefully cut away with a hacksaw or other fine tooth saw. Chamfer and deburr both cut ends. See Fig. 36.Determine the insertion depth mark from the Kimberly socket by halving the total socket length (Fig. 37).

Pipe Bedding & Backfill
A
The width of the trench should be as narrow as possible but at least 300mm greater than the outside diameter of the pipe (Dimension A plus B).Trenches deeper than 900mm (Dimension C) should be stepped and suitably shuttered so as to prevent accidental injury from collapsing sidewalls.The bottom of the trench should be free from stones, projections, soft spots, be reasonably uniform and graded to fall.Bedding should be to a class as specified by an engineer. In the absence of engineering instructions, it is advisable to use a bedding class for flexible pipes in accordance with SANS 1200LB where under traffic load and a Class C bedding elsewhere.The initial backfill should be of selected granular material compacted to a depth of 100mm (Dimension D) and covering the full width of the trench.It is good practice to backfill as the pipe laying progresses, leaving 300mm exposed on either side of joints for testing.Generally the use of concrete with flexible pipes in trenches is considered wasteful since it converts a flexible pipeline into a beam of negligible flexural strength.At depths of 700mm (Dimension E) and more, protection by normal well

compacted granular surround is generally adequate.At shallow cover depths where pipes may be subject to heavy traffic loadings, protection is best achieved by the use of concrete slabs on a cushion of hand compacted granular fill.Alternatively the pipeline may be protected by a reinforced pipe duct of greater diameter.
Where the 160 by 110mm reducing junction (UY64) is used to create
a branch connection leading to the ground level, care should be
exercised in the backfill and compaction surrounding the joint so as
to avoid excessive joint leverage. Branch access should be adequately
supported. See Fig. 43
