pipe does not release any chlorine into the water and can he recycled for further use the excellent ability of the pipe composition to provide pipes that can withstand high pressures can be seen in the water pressure test and the internal pressure creep test where water leakage does not occur further no cracks and fissures were seen in the flatness test which indicates the excellent pressure resistance characteristics of the composition pipes made from the above described composition are also advantageous in that they do not contain components such as lead which may be transmitted by the water further other detrimental factors such as increase in muddiness color change odor absorption loss of taste and the like normally associated with steel pipes does not occur additionally since the pipe does not contain any pvc chlorine does not get into the water from the pipe because to the excellent thermal stability and chemical characteristics of the pipe composition potassium permanganate normally used to purify drinking water may be used in lower quantities the present invention has been explained below in further detail with non limiting examples however the present invention is not restricted to these practical examples the polyphenylene ether resin used in the examples was poly 2 6 dimethyl 1 4 phenylene ether obtained from ge plastics co japan having an intrinsic viscosity of 0 46 dl g when measured in chloroform at 25 u00b0 c topolex 870st a high impact polystyrene commercially available from japan polystyrene co ltd was also used triphenyl phosphate tpp commercially available from daihatsu chemical industries ltd was used as a flame retarding agent adegastab mk2112 a phosphite stabilizer commercially.
