The insulation layer is made of rigid polyurethane foam with a density of 60kg/m3 to 80kg/m3, which can fully fill the gap between the steel pipe and the casing, and has a certain bonding strength, so that the steel pipe, the casing and the insulation layer form a solid whole. The polyurethane directly buried insulation pipe foam has good mechanical properties and thermal insulation properties. Generally, it can withstand 120 ℃. By modification or combination with other insulation materials, it can withstand 180 ℃

High temperature prefabricated direct buried insulation pipe is a type of direct buried prefabricated insulation pipe with good insulation performance, safety and reliability, and low engineering cost. Effectively solved the insulation, sliding lubrication, and waterproofing problems of prefabricated buried insulation pipes for high temperature heat transfer from 130 ℃ to 600 ℃ in urban centralized heating.

High temperature prefabricated buried insulation pipes not only have advanced technology and practical performance of traditional trench and overhead pipeline laying, but also have significant social and economic benefits, and are also powerful measures for heating energy conservation.

Advantages of directly buried insulation pipes:

(1) Low engineering cost

(2) Less land occupation, faster construction, and favorable environmental protection.

(3) Jacket tubes save energy, resist corrosion, have good insulation performance, and have a long service life.

(4) All are equipped with leakage alarm lines for safety. Once a leak occurs in a certain part of the pipeline, the accurate location and degree of leakage of the insulation pipeline can be displayed on the detection instrument through the transmission of the alarm line, in order to notify the leak detection personnel to quickly deal with the leaking pipe section and ensure the safe operation of the heating pipeline network.
