Yunnan seepage pipes, perforated corrugated HDPE pipe, salt drainage pipe, complete specifications HDPE perforated corrugated pipe, seepage control, blind drainage pipes, perforated corrugated pipe, HDPE perforated vertical drains bellows, also known as seepage pipes, drainage blind tube, polyethylene (PE) to add other additives to form a corrugated appearance of the new infiltration drainage plastic pipe, into a single, double-wall corrugated pipe perforated, light weight, strong under pressure, excellent bending properties facilitate construction and other features. As the product of the holes in the trough and is elongated, flat round hole effectively overcome the impact of the product is easily clogged drain side effects *. For different drainage requirements. Pore ??size may be 10mm × 1mm-30mm × 3mm, and may be at 360 degrees, evenly distributed within the range of 270 degrees, 180 degrees, 90 degrees and so on. Common Specifications: Φ50mm single wall corrugated pipe for drilling drainage tunnel hoop; Φ100mm double wall corrugated pipe for the tunnel drilling vertical and horizontal drainage; Φ400mm double wall corrugated pipe for central perforated drainage and embankment, road tunnel project vertical and horizontal drainage tube. Perforated corrugated HDPE pipe range widely used in highway, railway embankment, underground engineering, slope protection, tunnels, green belts, playgrounds, landfill and high water content caused by the drainage field. Description HDPE perforated corrugated pipe, also known as seepage control, blind drainage pipes, polyethylene (PE) to add other additives and the formation of a new exterior corrugated plastic pipe seepage drainage, divided into single, double wall drilling Bellows, light weight, strong to withstand the pressure, bending excellent performance characteristics of a HDPE perforated corrugated pipe, drainage Safety: orifice located troughs and peaks due to double-acting filter fabric, orifice clogging, its opening area up 116cm2 ??/ extended to ensure the smooth flow of permeable system. 2, corrosion resistance: Compared with the soft spring drains, plastic is not easy to rust. 3, strength and pliable organic combination: a unique double corrugated structure effectively improve the drainage effect of external pressure strength of the product, the drainage system is not affected by external pressure deformation. 4, the economy: the same caliber compared to other drains, its price is lower.
