Performance characteristics of plastic pipes

Within the framework of a review of a number of articles concerned with the performance characteristics of plastic pipes, an analysis of the known methods of determining the creep strength of polyethylene pipes is presented, and the shortcomings of the usual method of testing plastic pipes under constant internal hydrostatic pressure (as applied to polyethylene pipes) are discussed. The possibility of using tensile tests on rod specimens at constant stress to determine the long-time brittle strength of polyethylene pipes is considered.
