1, steel pipes:
Made of A3 killed steel seamless steel pipe, spiral seam steel pipe and welded steel pipe, performance indexes and the ministry of metallurgical department standard.
Generally, nominal diameter DN25-100 adopts the seamless steel pipe or welding steel pipe, according to the requirements of the project can provide users with all kinds of steel pipe.

2, the outer casing:
High-density polyethylene jacket pipe has high mechanical strength and good corrosion resistance, it can guarantee the pipes during transportation and installation is not affected by any damage caused by outside the industry. After installation on anti-corrosion waterproof protective effect.

3, insulation layer:
Insulation layer by using 40 kg/m3 density 80 kg cubic meters of rigid polyurethane foam plastics, the bubble fully fill pond between steel tube and the outer casing of and closely combining the three forming an organic whole. Polyurethane foam has good heat preservation performance, mechanical performance, heat insulation performance.
