scope:
This technical code applies for the electro socket-welding of fittings and tapping tees made of PE-HD1) according to DIN 16963, DIN 3543-4 and DIN 3544-1 with pipes made of PE-Xa (degree of cross-linking 75% to 90%) and PE-Xc (degree of cross-linking 60% to 75%) according to DIN 16892/93, that are being used for the conduction of gas, fluids and solids.
The electro socket-welding of PE-HD fittings with pipes made of PE-Xa or PE-Xc requires an additional proof by tensile creep tests according to DVS 2203-4 Supplement 1.
The maximum load of joints made with fittings of PE 80 and PE 100 corresponds with the allowed operating pressure according to tables 8 to 13 in DIN 8074 and DIN 16893.
1) The material indication is the specification of thermoplastics group and includes the types PE 63, PE 80 and PE 100. The information complies to the current standards.
