Thermal insulation supporting structure for hoisting part of low-temperature pipeline

Abstract

The invention relates to a thermal insulation supporting structure for a hoisting part of a low-temperature pipeline, which comprises a fixing belt, a hoisting ring and a plurality of supporting rods, wherein the fixing belt wraps the hoisting part of the pipeline to form an annular structure, the hoisting ring is arranged outside the fixing belt in a sleeving mode, the space between the hoisting ring and the fixing belt is filled with a thermal insulation layer, one ends of the plurality of supporting rods penetrate through the thermal insulation layer to be connected with the outer wall of the fixing belt and are evenly distributed to be of a radial structure, and the other ends of the supporting rods abut against and are fixed to the inner wall of the hoisting ring. According to the technical scheme, the thermal insulation layer arranged between the fixing belt and the hoisting ring can be prevented from being extruded, the protection effect on the thermal insulation layer is achieved, and the thermal insulation layer is prevented from being damaged due to extrusion friction between the lower portion of the pipeline and the hoisting ring.

Description

technical field [0001] The invention relates to the field of pipeline insulation structures, in particular to a heat insulation support structure for the hoisting part of a low-temperature pipeline. Background technique [0002] In production activities, pipelines are mainly used for the transportation of fluid materials. They can be divided into normal temperature, high temperature and low temperature according to temperature alone. Normal temperature pipelines usually only need anti-corrosion treatment on their surfaces, while high-temperature and low-temperature pipelines need to be treated on the basis of anti-corrosion. Make heat insulation materials to prevent heat loss and accidental burns in high-temperature pipes, and pressure changes in the internal medium caused by the contact between low-temperature pipes and external connections; the usual practice is to coat high-temperature pipes and low-temperature pipes with glass fiber and other heat-insulating materials. ...

[0002] In production activities, pipelines are mainly used for the transportation of fluid materials. They can be divided into normal temperature, high temperature and low temperature according to temperature alone. Normal temperature pipelines usually only need anti-corrosion treatment on their surfaces, while high-temperature and low-temperature pipelines need to be treated on the basis of anti-corrosion. Make heat insulation materials to prevent heat loss and accidental burns in high-temperature pipes, and pressure changes in the internal medium caused by the contact between low-temperature pipes and external connections; the usual practice is to coat high-temperature pipes and low-temperature pipes with glass fiber and other heat-insulating materials. However, for the hoisting pipeline passing through high altitude, it is necessary to use fixed structures such as lifting rings to lift the pipeline during the hoisting process, and the insulation material will squeeze between the coated heat insulation material and the lifting ring due to its own weight. Combined with the vibration generated by the fluid flow in the pipeline, the heat insulation material that is exposed to the stressed parts of the pipeline and the lifting ring under long-term action will be squeezed and rubbed and damaged
