TECHNICAL SOLUTIONS WATERTIGHTNESSS/IMPERMEABILITY IN PRESSURISED SECTIONS With the standard NBR joint, the PAM pipeline system is a combination of homogeneous parts designed to produce structures which are, and remain, watertight. The PAM solution The PAM ductile cast iron system displays excellent mechanical properties; the junction is the key element to guarantee watertightness of the structures, whether they operate by gravity or under pressure. PAM pipeline junctions (STANDARD or TAG 32 ® types) are made by simply pushing the pipes together, the gaskets being under high radial compression: the compression rates can reach 30 to 40 %. The elastomers chosen withstand the most severe tests, corresponding to their application. They are selected to retain their mechanical and physico-chemical characteristics over a long period of time. The tightness performance of the PAM system joints, under extreme conditions of use, is designed to cope with the mechanical stresses that the junctions are likely to suffer with time, such as shear, deflection or accidental loading. The compression rate of the elastomer gaskets prevents seepage, surface leakage, penetration of roots or pebbles at the junctions which can lead to the loss of water tightness of the networks. The specific design of PAM joints makes decompression impossible under shear forces. These features protect the environment and preserve the water tables. 18 Saint-Gobain PAM - SEWERAGE - 2012
TECHNICAL SOLUTIONS INTEGRAL ® junction with standard joint TAG 32® junction with TAG joint NITRILE* HR quality was chosen for all joints in the PAM system to withstand the effluents encountered in sewage. This grade complies with the requirements of the European standard: EN 681-1 type WG. * NITRILE = N.B.R. (identified by yellow marking). GRAVITY - water - air PERFORMANCE OF INTEGRAL ® PLUVIAL ® /TAG 32 ® SYSTEMS Internal pressure 2 bar 200 millibar External pressure 1 bar - Shear force 30 times DN (in Newtons) Factory test PRESSURISED > 20 bar 1 bar > 25 bar - PAM is the guarantee that the pipeline will be watertight first time, with no surprises when the tests are carried out, and will remain watertight!
