DESCRIPTION

The heat preservation fixing joint is based on the casing steel pipe, and the core pipe position is limited to three-dimensional (three-dimensional) by using three-piece jacket plates to prevent the surface of the casing from overheating due to the thermal bridge effect. The technology of breaking the heat bridge is adopted in the structure. Heat transfer is achieved. After ten years of engineering practice, the performance is reliable.

The prefabricated directly buried insulation fixing section comprises:

(1) Working steel pipes: According to the technical requirements of conveying medium, seamless steel pipes, seamless steel pipes, double-sided submerged arc spiral welded pipes are adopted.

(2) insulation layer: rigid polyurethane foam.

(3) protective shell: high density polyethylene or fiberglass reinforced plastics.

(4) Leakage alarm line: When manufacturing high-temperature prefabricated directly buried insulating pipe, an alarm line is embedded in the insulating layer near the pipe. Once leakage occurs somewhere in the pipe, the alarm line can be conducted through the alarm line, then the alarm can be made on the special testing instrument and the exact location of the leakage and the size of the leakage degree can be displayed so as to inform the maintenance personnel. Rapid treatment of leaking pipes ensures the normal operation of the heat supply network.

Standard application field of heat preservation fixed section: chemical industry: acid, alkali, salt manufacturing industry, chemical fertilizer, chemistry, rubber and plastics industries conveying corrosive gas, liquid, solid powder process pipe and discharge pipe. Thermal expansion pipe can be installed in the lined steel pipe power engineering: power plant process water backwater conveying, chemical water, waste slag, fly ash conveying. Smelting industry: transportation of corrosive medium in metal smelting. Mining industry: ore powder, slurry, slag, tailings discharge, backfill, ventilation, gas drainage and shotcreting. Industry: transportation of corrosive media, sewage and waste water. Oil field gas field: oily sewage, gas field sewage, oil and gas mixture, oil extraction and gathering process pipeline. Agricultural sprinkler irrigation: deep well pipe, filter pipe, culvert delivery pipe, drainage pipe, irrigation water supply pipe. Municipal industry: urban building water supply, drinking water, fire water, heat network backwater, gas, natural gas transmission, highway buried drainage and green belt irrigation channels.
