Thermal insulation pipelines are widely used for liquid and gas transportation pipe networks, chemical pipeline insulation engineering petroleum, chemical industry, centralized thermal heating net, central air -conditioning ventilation pipeline, municipal engineering, etc. High -temperature prefabricated insulation pipes are a kind of pre -pre -pre -pre -pre -preservation pipe with good thermal insulation performance, plus safety and reliability, and low engineering cost. Effectively solve the problem of the prefabricated pre -buried insulation pipes of high temperature heat transmission in the urban centralized heating in centralized heating.
High -temperature prefabricated direct -buried insulation pipes not only have advanced technologies and practical properties that are difficult to compare with traditional ditch and overhead laid -to -laying pipelines, but also have significant social benefits and economic benefits. They are also powerful measures for heating and energy saving. The high -temperature pre -buried thermal insulation pipe uses direct burial heating pipeline technology, marking that China's heating pipeline technology development has entered a new starting point.
The thermal insulation pipe is composed of steel pipes, glass fiber reinforcement cover, and glass fiber reinforced reinforced reinforcement shells. Its characteristics are: also include high temperature resistant insulation thermal insulation layers, lubrication layers, and elastic seals. This utility model effectively solves the problem of thermal insulation, sliding lubrication and waterproofing of naked tubes in the high temperature heat transmission insulation pipe in the central heating of central heating.
