Fasten Hopesun Polyethylene (РЕ) pipes are produced from high-density polyethylene resin, and the production process is strictly organized in accordance with GB/T related standards. The product does not contain heavy metal additives, does not scale, does not breed bacteria, does not cause secondary pollution to the transmission medium, and has good chemical stability.
PE pipe has good heat resistance and cold resistance, high rigidity and toughness, good physical and mechanical properties, impact resistance, strong shock resistance, flexibility and twisting performance, and adapts to а wide range of environmental changes. The РЕ pipe welding process is simple, and the mature welding technology ensures high interface strength, so the construction is convenient and the overall project cost is low.
The smooth inner wall of the РЕ pipe and the non-adhesive characteristics of the material itself determine the higher conveying capacity of the product, so the transmission energy consumption is lower.
