Yangzhou steel jacket steam prefabrication Thermal insulation pipe density polyurethane Application of insulation pipe: for heating Insulated pipeline Hot spring insulation The Conduit Heat supply and insulation pipeline, heat supply and insulation pipeline air conditioner Thermal insulation pipeline, steam insulation pipeline, cold and hot insulation pipeline, external wall insulation, etc. The polyurethane insulation pipe has the characteristics of * * * insulation, waterproof, anti-corrosion, thermal insulation, sound insulation, flame retardancy, cold resistance, anti-corrosion, light capacity, high strength, simple and convenient construction, and is not afraid of plant root thorns. It has become indispensable data for thermal insulation, waterproof plugging, sealing, etc. in the construction, transportation, petroleum, chemical, power, refrigeration and other industrial sectors. Polyurethane insulation pipes are used for insulation, cold insulation, oil pipeline, steam transmission and other pipeline projects of various indoor and outdoor pipelines, central heating pipelines, * * * air-conditioning pipelines, chemical, pharmaceutical and other industrial pipelines. Since the birth of polyurethane composition materials in the 1930s, rigid polyurethane insulation pipes have been rapidly developed as a kind of thermal insulation materials, and their application scale has become more and more extensive. Because of their simple construction, obvious energy-saving and anti-corrosion effects, they are widely used in various heat supply, refrigeration, oil transmission, steam transmission and other pipelines. It is widely used in various heating, cooling, oil and steam pipelines.
Polyurethane insulation pipes are widely used in liquid and gas transmission pipeline networks, chemical pipeline insulation projects, petroleum, chemical, central heating and heating networks, * * * air conditioning and ventilation pipelines, municipal projects, etc. High temperature prefabricated directly buried thermal insulation pipe is a kind of directly buried prefabricated thermal insulation pipe with good thermal insulation performance, safety and reliability, and low project cost. It effectively solves the problems of heat preservation, sliding lubrication and waterproof at pipe ends of prefabricated directly buried heat preservation pipes for 130 ℃ - 600 ℃ high temperature heat transmission in urban central heating. The high-temperature prefabricated directly buried insulation pipe not only has the advanced technology and practical performance unmatched by the traditional trench and overhead laying pipeline, but also has significant social and economic benefits, which is also a powerful measure for heat supply and energy conservation. The high-temperature prefabricated directly buried insulation pipe can play a good anti-corrosion role because the polyurethane rigid foam insulation layer is closely bonded to the steel pipe skin, which can isolate the infiltration of air and water. At the same time, its foam pores are closed, and its water absorption is very small. The high-density shell of polyurethane insulation pipe and the fiberglass shell of polyurethane insulation pipe have good anti-corrosion, insulation and mechanical properties.
Overview of directly buried thermal insulation pipes: directly buried thermal insulation pipes can be directly buried in 0.6-1.2m frozen soil layer (so people are used to calling them directly buried thermal insulation pipes or prefabricated thermal insulation pipes), the heat loss can be reduced by more than 40% compared with ordinary pipes, the working life can be increased by more than 3-5 times compared with other thermal insulation and anti-corrosion materials, and the service life can reach 30-50 years; The quality meets or exceeds the Chinese industry standards. Its complete thermal insulation system is characterized by low overall project cost, short construction period, long service life, energy conservation, environmental protection, etc. The continuous operating temperature is 130oC, and the peak height can reach 150oC.
