Problems solved by technology

However, when the medium is transported, the pipeline is prone to vibration, which will cause friction between the pipeline bracket and the pipeline cooling bracket, wear the pipeline cooling bracket, and affect the cooling effect
At the same time, in order to enhance the cold insulation effect and service life of the cold support, a cold insulation block is usually added between the pipe support and the pipe to ensure a certain cold insulation effect, but under the action of friction, the cold insulation effect of the existing cold insulation block will also be reduced. decreasing gradually

Abstract

The invention provides a polyisocyanurate cold insulation block, which is formed by pouring modified polyisocyanurate. The invention further provides a pipeline adjusting device comprising the cold insulation block. According to the invention, the cold insulation block prepared from the modified polyisocyanurate, provided by the invention, is excellent in strength, compression resistance, shock resistance, water resistance and moisture resistance, has excellent ultralow-temperature heat conductivity, reduces a medium, and is in a semi-circular ring shape, wherein the width of the cold insulation block is gradually reduced from one end to the other end, and it is guaranteed that a gap is reserved for horizontal left-right movement of the pipeline. The novel pipeline adjusting device is provided, wherein adjustment can be conducted according to vertical vibration of the pipeline, and stable transportation of the pipeline is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of pipeline brackets, in particular to a polyisocyanurate cold insulation block and a pipeline adjustment device comprising the cold insulation block. Background technique [0002] With the advancement of technology and the improvement of living standards, the scope of application of cryogenic liquefied substances such as liquefied natural gas, liquid nitrogen, liquid oxygen, and liquefied petroleum gas has gradually expanded. How to reduce energy consumption and waste during transportation is a difficult problem that must be solved. At present, most of the pipe supports and hangers are used to support the pipes with pipe supports. However, when the medium is transported, the pipeline is prone to vibration, which causes friction between the pipeline support and the pipeline cooling bracket, wears the pipeline cooling bracket, and affects the cooling effect. At the same time, in order to enhance the cold ins...
