Expansion joints for pipelines on SVOBODNOPODVIZHNYH SUPPORTS

摘要

The invention relates to pipelines, the compensator is designed to compensate for the bending moments and mechanical stresses arising at the joints of the pipeline with the main-outlet conduit by varying the pressure and temperature in the conduit laterals and the main pipe. The object of the utility model is to compensate for longitudinal thermal strains of the underground pipeline and lowering compressive, tensile and bending stresses arising in the nodes connecting piping tee laterals and bypass lines. The proposed design for compensator conduit comprises conduit outlet and the primary conduit, located on the freely-movable supports. Tie a knot above the ground. Payment bending moments and mechanical stress is achieved by allowing the free movement of punch assembly in a horizontal plane above the ground.
