Preformed Directly Buried Polyurethane Thermal Insulation Spiral Steel Pipe
Cangzhou spiral steel pipes company manufacture 219mm to 3500mm double face submerged arc welding SSAW SAWH spiral steel pipe in 6-25.4mm wall thickness with preformed directly buried polyurethane thermal insulation coating in conformity with ISO, EN, DIN, GB, SY, CJ standards for the spiral steel pipe to be anti-corrosion coated.
Applicable Standards: SY/T 0415-1996, CJ/T 114-2000, EN 253-1994, etc.
Preformed directly buried polyurethane thermal insulation steel pipe is made from steel pipe, polyurethane foam insulation layer and FRP outside protect coating layer.
The preformed directly buried polyurethane thermal insulation coating 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, and the anti-condensation engineering.
The preformed directly buried polyurethane thermal insulation coating has advantages as follows:
- Insulation performance is good, heat loss is only 25% of traditional pipe long-term operation to save energy, significantly lower energy costs.
- The preformed directly buried polyurethane insulating coating steel pipe 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.
- The preformed directly buried polyurethane insulating coating steel pipe also has good corrosion resistance and excellent resistance to impact at low temperature, can directly bury underground permafrost.
- Service life of the preformed directly buried polyurethane insulating coating steel pipe can reach 30 to 50 years, the correct installation and use can make the pipe network maintenance costs low.
- The preformed directly buried polyurethane insulating coating steel pipe can install alarm system, automatic detection pipe leakage faults, accurate fault location and automatic alarm instructions.
