Abstract: In order to study crack
propagation-arresting characteristics of steel pipe
construction, a new test installation was designed. The
experiments of 20 steel pipes, pipes with longitudinally weld,
pipes with circumferential weld and steel pipe with sleeve were
conducted. The testing results indicated that circumferential
weld in pipe with overmatching weld had beneficial effect on
crack propagation arresting properties and the mechanical split
sleeve can be used as crack arrester to prevent crack
propagation.
