Abstract

An arrestor for arresting an axial ductile propagating fracture in a pipeline transporting a high-energy fluid is made from a material such that the arrestor deforms sufficiently when encountering a propagating fracture that the propagating fracture continues at least under the arrestor but the arrestor has enough strength that it ceases the crack propagation without ring-off of the pipeline. The material is filled with fiber characterized by having a stress-strain curve that passes thru the ranges between about 25 and 200 ksi in stress, and a deformation ranging from between about 5% strain and 35% strain, and having a diameter ranging between about 0.002 and 0.020 inches.
