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: Small
