The structure draws lessons from the design of similar foreign products, using a unique structural form in which the pipe support and the inner wall of the steel casing serve as a sliding interface. The strong sealing performance of the steel casing has successfully solved the difficulty of waterproofing and impermeability. The outer wall of the outer casing is anti-corrosion, and the insulation layer is made of two layers of hydrophobic composite silicate insulation materials. The internal and external staggered seams are bandaged to reduce heat loss. The steel casing Insulation measures are taken on the supports to prevent thermal bridges.
The service life of the product is used for pipes that convey medium pressure not greater than . and temperature not higher than ℃. The service life can reach more than 10 years.
Prefabricated directly buried steam insulation pipes are composed of steel pipes for transporting media, hydrophobic composite silicate insulation layers, fiber cloth (aluminum foil), steel casings, and anti-corrosion layers.
Inner steel pipe specifications:&
Nominal diameter D adopts B seamless steel pipe and D and above adopts welded steel pipe conforming to . or spiral seam welded steel pipe conforming to /.
Insulation layer: The insulation layer material is made of two layers of hydrophobic composite silicate tube shells. The staggered seams are wrapped on the inner steel pipe, forming an integral body with the inner steel pipe, and sliding with the steel casing through the guide bearing.
