The Choice of Plastics for Gas Distribution Systems

 

Plastics Pipes Underground # 1970 Southampton

The Dutch Gas Institute have made two surveys of the use of plastic pipes in the Nethelands. The first survey was made in 1964 and the second survey was made in 1968. The most important facts of these two surveys are given in Table 1, together with an estimate of the current situation. It is estimated that 80% of the service connections currently being made are in plastics. 5070 of the mains in the pressure classes to 100 millibar is also estimated to be in plastics. 

These figures are the best indication of the way in which plastics have been accepted and are being used in the gas industry in Holland.

PVC products have suffered in the last years from attack by environmental activists. The production of PVC with its chlorine based raw material and the incineration of PVC with the suggested emission of dioxine have been used as arguments to try to curtail the use of PVC in all application areas. The PVC pipe...

Fig, 1 gives the last known figures (1-1-73) of materials used in the Dutch gas network at 8 bar and lower (under supervision of the gas boards). The figure shows that during the last 18 years more than 20,000 km of uPVC pipes have been laid, and that since 1966 about 3,200 km of high impact PVC have been applied. The...
