Hebei Shengqi Pipeline Anti-corrosion and Insulation Engineering Co., Ltd.

Corrosion Protection Layer: Protects the outer steel pipe from corrosion, extending the service life of the steel pipe.

2. External Steel Pipe: It protects the insulation layer from groundwater erosion, supports the working pipe, and can bear certain external loads, ensuring the normal operation of the working pipe.

Glass WoolMaintain medium temperature, ensuring the outer sheath surface remains at room temperature.

4. Barrier and Reflective Layers: Ensure organic foam materials do not enter the inorganic hard, high-temperature-resistant layer; reflect a portion of the high-temperature layer's heat.

5. Inorganic rigid insulating layer: withstanding high temperatures, ensuring the interface temperature between the inorganic and organic insulating layers, preventing the foam from carbonization.

6. Friction-reducing layer: Ensures free thermal expansion and contraction movement of the working pipe.

7. Working Steel Pipe: Ensures the normal flow of conveying medium.
