Polyurethane prefabricated directly buried insulation pipe is made of steel pipe, polyurethane rigid foam insulation layer and glass fiber reinforced plastic (ie, glass fiber reinforced plastic) outer sheath closely integrated prefabricated pipe. In this case,
Polyurethane insulation pipe has the characteristics of light weight, high strength, heat insulation, sound insulation, fire retardant, cold resistance, anti-corrosion, non-absorbent, easy construction and other outstanding features, has become the construction industry, transportation, petroleum, chemical, power, refrigeration and other industrial insulation, Waterproof plugging, sealing and other indispensable materials. Polyurethane insulation pipe for indoor and outdoor various pipes, central heating, refrigeration, oil, steam and other pipelines, central air conditioning pipes, chemical, pharmaceutical and other industrial pipe insulation, cold engineering.
Prefabricated polyurethane insulation pipe insulation than the traditional various types of pipe insulation has a very prominent advantages:
1, good insulation properties, heat loss is only 25% of the traditional pipe, long-term operation can save a lot of energy, significantly reduce energy costs. In this case,
2, has a strong waterproof and corrosion resistance, without additional pipe ditch, can be directly buried underground or water, construction is simple and rapid, comprehensive low cost.
3, in low temperature conditions also has good corrosion resistance and impact resistance, can be directly buried underground frozen soil.
4, the service life of up to 30-50 years, the correct installation and use of pipe network maintenance costs can be very low.
5, can be set up alarm system, automatic detection of pipe network leakage fault, accurate fault location and automatically indicate the alarm.
