ABSTRACT:
A crack arrestor for a pipe is in the form of a clock spring defined by a spiral band of high tensile strength material having an elasticity maintaining the band in contact with the pipe. A method for making the crack arrestor includes saturating high tensile strength filaments with a resin, winding the saturated filaments around a mandrel in a plurality of convolutions, and establishing an elastic set in the convolutions by curing the resin.
