A kind of hot water engineering pipeline anti-corrosion and thermal insulation structure

Abstract

The invention discloses an anti-corrosion and heat-preservation structure of a hot water engineering pipeline, which comprises a heat-insulating shell and two sections of the pipeline body. The outer sides of the two sections of the pipeline body are provided with insulation sleeves, and the joints of the two insulation sleeves are installed with The sealing flange, two installation grooves are symmetrically opened on the side wall of the heat insulation casing, and the two heat preservation sleeves respectively pass through the corresponding installation grooves and extend to the outside of the heat insulation casing, and the inside of the heat insulation casing A guide plate is fixedly installed on the top wall. The anti-corrosion and heat-preservation structure in the present invention can reduce the humidity in the heat-insulating shell, avoid the electrochemical reaction between the metal structure and the non-metal structure in the heat-insulating shell, and cause various corrosion problems of various parts; when high-temperature steam leaks, The signal transmitter and the warning light warn the staff at the same time, which is convenient for the staff to quickly locate the location of the steam leak, and the signal transmitter and the warning light are in two parallel circuits, which has a high fault tolerance rate.

Description

technical field [0001] The invention relates to the technical field of pipeline anticorrosion, in particular to an anticorrosion and heat preservation structure for pipelines in hot water engineering. Background technique [0002] Hot water projects use clean energy or recover heat from waste water to heat cold water to reduce energy consumption. This process often involves the transmission and heat exchange of high-temperature and high-pressure steam, and the piping system is subject to vibration after long-term use. Influenced by factors such as temperature difference, mutual pulling between pipes, etc., the sealing performance will be reduced, not only the heat preservation effect will be deteriorated, but also the leaked high-temperature steam will also accelerate the electrochemical reaction of various structures in the system, causing the pipe system to be corroded and damaged. In the existing technology, the tightness of the pipeline system is mostly judged by detecti...
