Black jacket yellow jacket directly buried insulation steel pipe
Specification of Black Jacket Directly Buried Insulating Steel Pipe: DN50mm-DN2000mm
Black jacket directly buried insulation steel pipe material: Q235B, Q345B, 10 # steel, 20 # steel, X42-X80 grade
Specification for Black Jacket Directly Buried Insulating Steel Pipe: CJ/114-2000
The outer layer of black polyethylene material is called black jacket insulation pipe.
A high-pressure foaming machine is used to inject rigid polyurethane foam plastics into the cavity formed between the steel pipe and the outer cover at one time, and then polyethylene is used to stop the disposal of the outer surface of the steel pipe to form the outermost maintenance layer.
The polyethylene shell is directly buried in the insulation pipe, and the high density polyethylene insulation pipe directly buried prefabricated heat preservation pipe is tightly combined with the steel pipe, polyurethane rigid foam insulation layer and high density polyethylenes coat pipe.
Directly buried heat preservation pipes are mainly used in urban central heating network, petroleum storage pipeline, water transmission pipeline in alpine region and industrial pipeline engineering in production area. Because the polyurethane rigid foam insulation layer is tightly bonded to the outer skin of the steel pipe, the infiltration of air and water can be isolated, and good anticorrosion effect can be achieved. At the same time, its foaming holes are closed and its water absorption is very small. High density polyethylene shell and FRP shell have good anti-corrosion, insulation and mechanical functions.
