Application of PE water supply pipe fittings in drainage engineering

Since the 1990s, China began to produce and use PE water supply pipe, Shaoxing electrofusion pipe fittings in recent years, the rapid development of manufacturers and products have gradually increased. The product is environmentally friendly, safe, energy-saving products, can replace the high energy consumption of cement, cast iron, ceramics and other materials made of pipe.

Widely used in municipal construction and other areas of the exhaust pipe. Jiaxing electrofusion pipe fittings HDPE pipe characteristics (1) good hydraulic conditions. HDPE pipe inner wall surface is smooth, the pipe coarseness coefficient is low, so in the same pipe diameter conditions, than reinforced concrete drainage pipe throughput of about 30%, that is, conveying the same amount of sewage flow, HDPE pipe diameter can be smaller than the reinforced concrete pipe Wenzhou electrofusion pipe fittings of a pipe level. (2) good sealing, leakage can achieve zero. As the pipe connection can use electric welding technology to ensure that the joints of the secondary pipe completely dissolved, the pipe interface does not leak. (3) Good impact resistance. The pipe wall adopts the ‘I-type’ structure, impact resistance, pressure resistance, foundation sinking conditions will not break, and deformation of the recovery is strong, any foundation has good adaptability. (4) corrosion resistance, good anti-aging properties.

The raw material of HDPE pipe is polymer polyethylene, so it can effectively resist the corrosion of acid, alkali, salt and other media. Many research departments have conducted systematic experimental research on the performance of the pipe, the characteristics of landfill engineering, pipe design and construction. Tianjin, Shanghai, Lanzhou, Taiyuan, etc. are compiled corresponding local standards for HDPE pipe municipal drainage engineering applications to provide a scientific basis.
