Cold-insulation pipe support for deep cold pipeline and pipe support construction technology

Abstract

The invention discloses a cold-insulation pipe support for a deep cold pipeline. The pipe support comprises a deep cold pipeline, a sealing rubber layer, multi-layer cold-insulation layers, a moisture-proof layer, a metal thin coating layer, a rubber buffer layer and pipe clamps, wherein the sealing rubber layer, the multi-lay cold-insulation layers, the moisture-proof layer, the metal thin coating layer, the rubber buffer layer and the pipe clamps are arranged on the deep cold pipeline in sequence from the inside to the outside; the pipe clamps are divided into an upper pipe clamp and a lowerpipe clamp which are oppositely coated on the outer side of the rubber buffer layer, the two sides of the upper pipe clamp and the two sides of the lower pipe clamp are bent to form overlap edges with the width of 50 mm, and the overlap edges are clamped up and down through bolts. According to the cold-insulation pipe support for the deep cold pipeline, the connection and support of the deep coldpipeline is realized, and the cold-insulation layers with the multi-layer structure can effectively guarantee the heat preservation performance of the positions of the cold-insulation layers.

Description

technical field [0001] The invention relates to a pipe holder, in particular to a cryogenic pipeline cold-preservation pipe holder and its construction technology. Background technique [0002] With the advancement of technology and the improvement of human living standards, the application range of cryogenic liquefied substances such as liquefied natural gas (LNG), liquid nitrogen (LN2), liquid oxygen (LO2), liquid carbon dioxide (LCO2), and liquefied petroleum gas (LPG) has gradually increased. Expansion, especially LNG, consists mainly of methane. LNG is condensed into a liquid by cooling gaseous natural gas at normal pressure to -162°C. The storage and transportation space can be greatly saved after natural gas is liquefied. The volume after liquefaction is about 1 / 600 of the gaseous volume, and it has the characteristics of large calorific value and high performance. LNG is a clean and efficient energy source. As a clean energy source, it is becoming more and more pop...

Problems solved by technology

[0003] However, the current domestic transportation of cryogenic medium represented by LNG still relies on tank trucks or gaseous pipeline transportation, resulting in serious waste of energy consumption

[0004] In response to this situation, there are some prefabricated cryogenic pipelines on the market, which combine the pipeline and the insulation layer into one, and can be installed directly on site. However, although these prefabricated integrated pipelines are easy to install, it is difficult to achieve insulation at the joints of the pipelines. Usually, it is connected by conventional pipe support, which can only play the role of supporting connection, and cannot realize the heat preservation of this part
