Main product uses are as follows: heating insulated pipe, hot-spring insulated pipe, district-heating insulated pipe, space-heating insulated pipe, air-conditioning insulated pipe, steam insulated pipe, hot-and-cold insulated pipe, and exterior-wall insulation. PU insulated pipe features high-efficiency thermal insulation, waterproofing, corrosion protection, heat insulation, sound insulation, flame retardance, cold resistance, light weight, high strength, simple and convenient construction, and resistance to plant-root puncture. It has become an indispensable material for thermal insulation, waterproofing, leak sealing, and sealing in construction, transportation, petroleum, chemical, electric-power, and refrigeration industries.

　　PU insulated pipe is used for thermal insulation and cold insulation of various indoor and outdoor pipelines, district-heating pipelines, central air-conditioning pipelines, and chemical and pharmaceutical industrial pipelines, as well as oil-transmission and steam-transmission pipeline projects. Since the advent of PU materials in the 1930s, rigid PU insulated pipe has been rapidly developed as an excellent thermal insulation material, and its range of use has become ever wider. Because it is simple to install and offers marked energy-saving and anti-corrosion effects, it is widely used on heating, refrigeration, oil-transmission, and steam-transmission pipelines.
