The Critical Size of Defect in Polyethylene Pipes because of their Cracking

Abstract:

In the work the possibility of the rapid crack propagation was analyzed in pipe made from polyethylene with the internal defect about the shape of the elliptical fissure. Pipes made from polyethylene are applied to the building of water-pipes. Critical dimension of such fissure was calculated because of the possibility of rapid cracking the pipe in low temperatures. Calculations were carried out for the nominal pressure during the exploitation of the pipeline and for raised pressure in the test of the tightness of the pipeline. Residual stresses resulting from the production engineering of pipes were also considered in the analysis.
