Practical applications of insulated steel pipes

Insulated pipes are widely used in liquid and gas transportation pipe networks, chemical pipeline insulation projects in petroleum, chemical industry, central heating networks, central air-conditioning ventilation ducts, municipal projects, etc. High-temperature prefabricated direct-buried thermal insulation pipe is a direct-buried prefabricated thermal insulation pipe with good thermal insulation performance, safety and reliability, and low project cost. Effectively solves the problems of thermal insulation, sliding lubrication and waterproofing of exposed pipe ends of prefabricated directly buried insulated pipes for high temperature heat transfer in urban central heating of 130℃-600℃.

High-temperature prefabricated directly buried insulated pipes not only have advanced technology and practical performance that are unmatched by traditional trench and overhead pipes, but also have significant social and economic benefits, and are also a powerful measure for heating and energy saving. High-temperature prefabricated direct-buried insulated pipes adopt direct-buried heating pipeline technology, marking that the development of China's heating pipeline technology has entered a new starting point.

The insulation pipe is composed of a steel pipe, a fiberglass inner sheath, and a fiberglass outer shell. It is characterized by: it also includes a high-temperature-resistant thermal insulation layer, a lubricating layer, and an elastic seal. The utility model effectively solves the problems of thermal insulation, sliding lubrication and waterproofing of exposed pipe ends of prefabricated direct-buried thermal insulation pipes for high-temperature heat transmission in urban central heating at 130°C-600°C.
