This etail Sheet must be read in conjunction with the Front Sheet, which gives the Conditions of Certification and the product s position regarding the Highways Agency requirements. Technical Specification Table 1 Pipe dimensions 1 escription 1.1 Ultra-Rib pipes have a solid wall and a repeating pattern of radial ribs perpendicular to the axis of the pipe. The ribs provide a housing for type WC elastomeric ring seals to BS EN : The pipes, golden brown or black in colour, are extruded in PVC-U and produced in three diameters with either plain ends (spigot X spigot) or with one end socketed (socket X spigot). of the pipe and pipe sockets are given in Tables 1 and Ultra-Rib fittings are golden brown or black in colour and injection moulded in PVC-U or polypropylene (PP). Where applicable, they are all socketed and have the same socket depths as the corresponding diameter of pipe socket. The range of fittings covered by this etail Sheet is shown in Table Continuous quality control is exercised during manufacture to maintain product quality and includes checks for dimensional accuracy, impact resistance and short-term stiffness on the pipes and for dimensional accuracy, and impact resistance on the fittings. 1.5 Each pipe length is stamped with the manufacturer s name and internal diameter. Each fitting is stamped with the internal and external diameters, and the product code number. 1.6 A label is attached to the 300 mm by 150 mm, 45 /S unequal junction fitting bearing the legend Handle with care. 2 elivery and site handling 2.1 Handling, storage and transportation should be in accordance with BS : The 300 mm by 150 mm, 45 /S unequal junction fitting must be handled with care. 2.3 When long-term storage is envisaged, the pipe and fittings must be protected from direct sunlight.

5 4 Strength 4.1 The pipe can be used as an alternative to the plastics pipe for foul and surface water drains in Table 5/1 of the MCHW, Volume For the determination of safe bedding depth to Highways Agency Standards HA40, pipe may be assumed to have a standard dimension ratio (SR) equivalent of not greater than The nominal short-term stiffness of pipe and fittings is not less than 8 knm 2 and creep ratio Performance of joints 5.1 The performance of correctly assembled joints will not be adversely affected by thermal expansion or contraction. 5.2 Joints in the pipeline remain watertight under conditions of pipeline movement in excess of those expected to occur in normal good drainage practice and comply with the MCHW, Volume 1, Clause Flow characteristics 6.1 The products will have normal flow characteristics associated with PVC-U underground sewerage systems. 6.2 Full bore discharges and velocities are available from H R Wallingford and I H Barr Table for Hydraulic esign of Pipes, Sewers and Channels, Volume 2, 7th Edition. The values are based on the Colebrook-White equation. 7 Resistance to chemicals 7.1 The products are suitable for use where pipes and fittings included in the MCHW, Volume 1, Table 5/1, are normally used. They have adequate resistance to the type and quantities of chemicals likely to be found in surface water. 7.2 etails of the chemical resistance of PVC-U and PP are given in CP : Practicability of installation The products are light in weight and are installed easily under normal site conditions. 9 Rodding 9.1 rains incorporating the product can be rodded easily using conventional flexible drain rods. Toothed root cutters, as used with some mechanical cleaning systems, could damage the fittings and should not be used. 9.2 The system has adequate resistance to water cleansing using pressure jetting equipment. It is recommended that low-pressure, high-volume systems are utilised in accordance with MCHW, Volume 1, Clause urability In the opinion of the BBA, when used in the context of this etail Sheet, no significant deterioration of the products, will take place and installations will have a life equivalent to traditional PVC-U drainage systems. Installation 11 General Installation must be in accordance with the Highways Agency Requirements. 12 Procedure 12.1 The pipe is cut midway between the small ribs as shown in Figure Swarf is removed from the pipe end The pipe spigots and sockets are cleaned and the sealing ring is checked to ensure that it is correctly seated (not twisted) between the second and third ribs of the pipe end The manufacturer s lubricant is applied generously to the whole of the inside area of the socket and to the sealing ring, making sure that it does not subsequently become contaminated with dirt The pipe is offered to the socket, aligned and pushed fully home Jointing to other materials must be carried out in accordance with Ultra-Rib Specifier Guide Pipes and fittings must have adequate protection against damage from site traffic.
