The role of thermal insulation steel pipes in converting coal to electricity

Jan 12 03:52 2021 chase Liu Print This Article

Coal-to-electricity conversion refers to the conversion of coal-fueled boilers and other tools used for heating to electric heating. Under current environmental protection requirements, it can only be changed to clean energy. Coal-to-clean energy accounts for about 80% of the share , It is widely used because of fast electric transmission and fast heating.

The heat transfer from coal to electricity is still hot water,Guest Posting so hot water is still used to transport hot water. Insulating steel pipes still play an irreplaceable role in other conveying products in the coal-to-electricity conversion, because the heat loss of insulated steel pipes is very small when transporting the medium. In addition, the insulation steel pipe has a long service life, low cost, high social benefit, and simple construction. The insulation steel pipe also has an alarm line. Once there is water leakage, it will immediately report to the police to deal with hidden dangers in time.

 

The superior performance of the insulation steel pipe is due to its reasonable structure:

 

Insulation steel pipe is mainly composed of four parts.

 

  • Working steel pipes: Seam steel pipes, seamless steel pipes, double-sided submerged arc spiral welded steel pipes are used according to the technical requirements of the conveying medium.

 

The ASTM A500 specification covers cold-formed welded and seamless carbon steel tubing in round, square, rectangular, and “special” shapes for welded, riveted, or bolted construction applications, as well as for general structural purposes.

 

(2) Insulation layer: use rigid polyurethane foam.

 

(3) Protective shell: use high-density polyethylene or glass fiber reinforced plastic.

 

  • Leakage alarm line: When manufacturing high-temperature prefabricated direct-buried thermal insulation pipes, an alarm line is embedded in the insulation layer close to the steel pipe. Once a leak occurs in a certain part of the pipe, it can be used in a special detection instrument through the conduction of the alarm line. The upper alarm will show the exact location of the water leakage and the extent of the leakage, so that the maintenance personnel can be notified to quickly deal with the leaking pipe section and ensure the safe operation of the heating network.
