Construction method of heat pipeline

Abstract

The invention provides a construction method of a heat pipeline. The construction method includes the specific steps that S1, multiple groups of pipeline supports are arranged along the two sides of the to-be-erected heat pipeline at intervals, and a pipeline bracket for supporting the heat pipeline is fixed between each group of pipeline supports; S2, the to-be-erected heat pipeline is subjectedto heat insulating pretreatment; S3, the heat pipeline is hoisted to the pipeline brackets of the pipeline supports through hoisting equipment and is mounted; and S4, after being mounted, the heat pipeline is subjected to pressure water testing, the heat pipeline is subjected to leakage detection, if it is detected that heat leaks, leakage portions need to be overhauled again, and if it is detected that no heat leaks, construction of the whole heat pipeline is completed. The measure of heat insulating pretreatment is carried out before the pipeline is laid, the heat pipeline can be subjected to heat insulating and heat replenishing, heat transmission of the heat pipeline is guaranteed, leakage of the heat pipeline can be detected in time, and heat losses are avoided from the source.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a thermal pipeline construction method. Background technique [0002] At present, with the large-scale development of my country's urban construction and central heating industry, the scale of efficient and energy-saving heat pipe network construction is expanding day by day. Thermal pipelines are pipelines used to transport thermal fluids. However, during the laying process of traditional thermal pipelines, due to factors such as man-made or pipeline material defects and self-corrosion, pipeline damage and leakage often occur, and there are no other temperature compensation measures, resulting in Heat transfer is limited, efficiency is reduced, or even blocked. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and provides a thermal pipeline construction method. [0004] In order to achieve the above object, the p...
