Keywords : pipeline * local stress state * high pressure
Subject RIV: JL - Materials Fatigue, Friction Mechanics

The local effects of the spiral welds on the stress and strain state of the pipe wall were investigated in the hydraulic strength tests of gas high-pressure pipelines. The influence of the spiral welds and notches on the pipe state of stress were investigated experimentally together with the numerical simulation of the behaviour of pipelines.
