Preformed Directly Buried Polyurethane Insulating

    Preformed directly buried polyurethane insulating pipe is made from steel pipe, polyurethane foam insulation layer and FRP outside protect layer.
    It has light capacity , high intensity, insulation, sound insulation, flame retardant, cold-resistant, anticorrosion, non-absorbent, simple construction and direct superior characteristic, has become the construction, transportation, petroleum, chemical industry, electric power, refrigeration industry departments heat insulation and waterproofing plugging, sealing the indispensable materials. It widely used to various pipeline, indoor central heating, refrigeration, oil, losing steam pipe, central air conditioning pipeline, chemical, pharmaceutical and other industrial pipe heat preservation, the anti-condensation engineering.It has advantages as follows:
    1.insulation performance is good, heat loss is only 25% of traditional pipe long-term operation to save energy, significantly lower energy costs.　　　
    2.Have strong waterproof and corrosion resistant capability, do not need to environment, can be directly attached to embed underground or water, construction is quick, comprehensive cost is low.
    3. It also has good corrosion resistance and excellent resistance to impact at low temperature, can directly bury underground permafrost.
    4.Service life can reach 30-50 years, the correct installation and use can make the pipe network maintenance costs low.
    5. It can install alarm system, automatic detection pipe leakage faults, accurate fault location and automatic alarm instructions.
