Abstract: The small scale steady state (S4) test is effective to simulate the rapid crack propagation behavior for the polyethylene fuel-gas distribution pipe line. The S4 testing device was developed. The S4 tests are conducted for the PE80 polyethylene pipe at different temperature and inner pressure, the arresting curve is gotten. The effects of welding procedure, inner pressure and temperature on arresting behavior for the PE80 polyethylene pipe are discussed also.

Key words: Arresting performance, Rapid crack propagation, Small scale steady state
