Crack Arrestor

Crack Arrestor

STOPS PROPAGATING DUCTILE FRACTURES IN GAS TRANSMISSION LINES

Clock Spring Crack Arrestors are produced from a high strength “memory matrix” composite.

Designed to stop propagating ductile fractures in gas transmission lines, during the arrest of the fracture, the Crack Arrestor is held in place by the memory matrix composite.

A Crack Arrestor can easily be installed over the pipeline coating by two crew members in a few minutes on a pipe of any diameter.
