Product Features
High-temperature prefabricated direct-buried insulated pipe adopts direct-buried heating pipeline technology
Product Details
Polyurethane insulated steel pipes for heating are widely used in pipelines for transporting liquids and gases, as well as in chemical pipeline insulation projects, petroleum and chemical industries, centralized heating networks, central air conditioning ventilation pipelines, municipal engineering, etc. High-temperature prefabricated buried insulated pipes offer excellent insulation performance, high safety and reliability, and low engineering costs. They effectively solve the insulation, sliding lubrication, and waterproofing problems at the pipe ends for prefabricated buried insulated pipes used in urban centralized heating systems at high temperatures of 130℃-600℃. High-temperature prefabricated buried insulated pipes not only possess advanced technology and practical performance unmatched by traditional trench and overhead pipeline laying methods, but also demonstrate significant social and economic benefits, serving as an effective measure for energy saving in heating systems.
The use of prefabricated buried insulated pipes in high-temperature heating systems marks a new starting point in the development of heating pipeline technology in China. Prefabricated buried insulated pipelines offer high insulation efficiency, waterproofing, corrosion resistance, heat insulation, sound insulation, flame retardancy, cold resistance, corrosion resistance, light weight, high strength, simple and fast construction. Heat loss can be reduced by more than 40% compared to ordinary pipelines, and the service life is 3-5 times longer than other heat-insulating and anti-corrosion materials, reaching 30-50 years.
