Production Description

● High strength. Excellent compression and impact resistance;

● Good toughness. Excellent shock resistance, suitable for soft soil and quicksand foundation;
● Strong water-passing ability. The inner wall is smooth, the water resistance is small, and there is no scaling;
● Easy to connect. It has good sealing performance and no leakage;
● Chemical resistance. no pollution;
● Good low temperature resistance. Has good electrical insulation properties;
● Light weight. It is easy to carry and install, with low engineering cost and long service life.
● High ring stiffness: The double-wall corrugated pipe adopts a double corrugated structure, which greatly improves the ring stiffness of the pipe, can resist external pressure, and does not affect the drainage effect.
● Low temperature resistance: The catalytic temperature of HDPE double-wall corrugated pipe is -70°C, and the temperature usually does not exceed -30°C during winter construction, and there is no need to take protective measures even in winter construction.
● Good corrosion resistance: HDPE molecules have no polarity, and have good chemical stability. Most chemical media do not have a destructive effect on it. Common installation environment soil, acid and alkali, electricity, etc. cannot damage the pipeline, and the service life can reach 50 years. above.
● Ground subsidence resistance: Due to the reasonable design of the HDPE double-wall corrugated pipe structure, it can be slightly deflected, making it both rigid and flexible, not affected by ground subsidence, and can withstand harsh environments.
● Low project cost: Under the same conditions, HDPE double-wall corrugated pipe only needs half of the raw materials compared with other solid-wall pipes of the same material and specifications, the pipe wall is thin, and the relative cost is also low. Compared with other pipes of the same diameter, the HDPE double-wall corrugated pipe can pass through a larger flow rate. In other words, under the same flow requirements, the HDPE double-wall corrugated pipe with a smaller diameter can be used.
● Convenient construction: DPE double-wall corrugated pipe has light weight, convenient handling and connection, which greatly reduces transportation costs and improves construction efficiency.

Application Area

● Municipal engineering rainwater, sewage discharge and residential area drainage works;
● Water conservancy irrigation and water supply and drainage of farmland;
● Sewage treatment, drainage and transportation of garbage disposal sites;
● Chemical industry, mine ventilation and chemical industry, mine for fluid transportation;
● Communication cable, optical cable sheath, power cable sheath;
● Well wall pipe (opening double-wall corrugated pipe) for well sinking project;
● Fishery water delivery.
