Butt fusion joining polyethylene pipes - and assessing the resultant joint strength

摘要

The advent of polyethylene pipe to carry potable water, fuel gases and effluent has meant a quick and reliable method of joining them, together with good weld strength, was needed. The author describes the mechanical properties of the polyethylene pipe, the butt fusion joints and the test methods used in assessing both. This data is used in determining the design and the installation and the predicted service life of the pipe.
