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.
