Qingdao Chaofeng Plastic Machinery Co., Ltd. specializes in producing PE seepage pipes, pe pipes, seepage pipes, garden ground pipes, drip irrigation pipes, wave-shaped hard water pipe production lines.

Material: It is modified by high-strength composite material, with good toughness and strong bearing capacity. The porosity is more than 95% and it is not easy to block. The recovery performance is good. It can effectively collect water seepage in the soil and remove it in time and effectively.

The plastic seepage pipe is made of acid-base and anti-aging composite material, so it can maintain its good state and water seepage performance under the soil.

The plastic seepage pipe has a strong specific gravity and is simple and convenient to construct. It is suitable for the construction and installation of geographical features under various complicated conditions.

Widely used in tunnel anti-seepage drainage, roadbed drainage of railways and highways, soft foundation embankment, retaining wall anti-filtration, slope and slope drainage, drainage and dampproofing of underground buildings, lawn drainage system, rooftop, golf course, The collection of gardens, hydropower stations, sewage treatment plants and landfills are widely welcomed by the engineering community.

Features: a) high compressive strength and good pressure resistance

The plastic seepage pipe itself is made of a plurality of modified plastic wires with toughness, and there is no possibility of being crushed or destroyed. Under the pressure of 250kpa, the cross-sectional void ratio is still above 60%. Even if a large pressure is applied, there is always a water-passing gap, there is still 10-15% of the pores, and the recovery is good.
