Axial fixing device for marine low-temperature non-insulated pipe system and using method

Abstract

The invention discloses an axial fixing device for a marine low-temperature non-insulated pipe system and a using method and relates to the field of ship building. The axial fixing device comprises abase, a pipe clamp, base plates and an axial stop assembly, wherein the base is made of H-shaped steel; the pipe clamp is of a door-shaped structure formed by welding three pieces of H-shaped steel, and the pipe clamp is welded to the base; the base plates are four plates made of polytetrafluoroethylene materials, three base plates are connected with the three pieces of H-shaped steel of the pipeclamp through bolts separately, and the other base plate is connected to the base through the bolt; and the axial stop assembly is installed on the base, the axial stop assembly is composed of two sets of identical assemblies, and the two sets of assemblies are symmetrically arranged along the base. The axial fixing device solves the problems that in the prior art, during axial limiting of a pipesystem, deviation exists between an original limiting form and the actual situation, the safety of the pipe system is affected and the space is limited; and the device is simple in structure and highin practicability, and has a good application effect on an actual ship.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to an axial fixing device for a marine low-temperature non-insulated pipeline system and a use method thereof. Background technique [0002] Marine pipe clamps are components installed on piping systems to limit pipe displacement. Due to the characteristics of thermal expansion and contraction of materials, cryogenic piping systems will have large displacements under large temperature differences, especially along the direction of the piping. Therefore, in order to prevent excessive axial displacement of the pipeline, it is necessary to limit the axial direction of the pipeline. [0003] The traditional way to limit the axial position of the pipeline is to weld a doubler plate on the pipeline, weld a section of straight pipe on the doubler plate, and limit the straight pipe through the corresponding pipe clamp form, so as to achieve the purpose of axial limit of the pipeline system . ...
