Abstract

The paper deals with the estimation of the load carrying capacity of the bellow compensator DN100, made of stainless steel AISI 304, which is supposed to be used for providing the necessary level of deformability of main buried gas pipelines in the mining production areas. Experimental investigations of the compensator under cyclic loading by tension-compression with the simultaneous action of working internal pressure are carried out. According to the results of experimental research and numerical simulation, it is shown that such compensators can be used as structural elements of main buried gas pipelines in the mining production areas.
