Polyurethane polyurethane insulation points from the inside to the outside three layers: the first layer of insulation: Working pipe layer based on design and customer requirements are generally used seamless steel pipe, spiral pipe and straight pipe joints. Steel surface after shot blasting Advanced Process jacket pipe insulation, pipe rust rating up to GB8923-1988 standard Sa2 grade, surface roughness up GB6060.5-88 standard R = 12.5 m. Second layer: polyurethane insulation layer: high pressure foaming machine with a cavity between the pipe and the outer protective layer is formed in a one-time injection of liquid is made of rigid polyurethane foam, commonly known as "pipe-in-pipe foam." The third layer: high-density polyethylene protective layer: a certain thickness preformed black or yellow polyethylene plastic pipe. First, its role polyurethane insulation protection against mechanical hard object damage, and second, anti-corrosion, waterproof. 4. Small footprint, and fast construction, favorable environmental protection. Buried heating pipe does not require masonry massive trench polyurethane insulation pipes, pipe insulation simply bury people underground, thus greatly reducing the project covering steel jacket pipe insulation, reducing the earth excavation is about 50%, reduce civil 90% of the amount of masonry and concrete. Meanwhile, heat pipe trenching parallel processing and on-site, just live joints, can shorten the duration of about 50%. High temperature pipe insulation prefabricated buried pipe insulation pipe insulation _ engineering _ Hainan emerging Albert Albert provided by the County of new anti-corrosion insulation Engineering Limited.
