Supply Guangdong cheap hdpe double wall corrugated pipe HDPE perforated corrugated pipe, seepage control, blind drainage pipes, perforated corrugated pipe, longitudinal drains Jiangtai Technology hdpe hdpe corrugated pipe manufacturers pure raw bellows random sampling welcomed patrons guarantee cheap 186-0379--3535 HDPE perforated corrugated pipe, also known as seepage control, blind drainage pipes, polyethylene (PE) to add other additives to form the exterior of the new corrugated plastic pipe drainage infiltration , divided into single, double wall corrugated pipe perforated, light weight, withstand the pressure strong, excellent bending performance, ease of construction and other features. As the product of the hole in the trough and is elongated, effectively overcome the flat products susceptible to plugging the hole affect draining effect of the state. For different drainage requirements. The size of the holes may be 10mm × 1mm-30mm × 3mm, and can be 360 ??degrees, evenly distributed within the range of 270 degrees, 180 degrees, 90 degrees and so on. HDPE perforated corrugated pipe characteristics 1, drain safety: orifice located trough, as a two-way effect peaks and filter fabric, orifice clogging, the opening area of ??up to 116cm2 ??/ extended to ensure smooth permeable system. 2, corrosion resistance: Compared with the soft spring drains, plastic not rust. 3, strength and pliable organic combination: a unique dual damascene structure effectively improve the drainage effect of external pressure strength of the product, the drainage system is not affected by outside pressure deformation. 4, the economy: the same caliber compared to other drains, the price is low. HDPE Common Specifications: Φ50mm single-wall corrugated pipe for drilling a tunnel to drain ring; Φ100mm double-wall corrugated pipe used for tunnel drilling vertical and horizontal drainage; Φ400mm perforated double wall corrugated pipe for central drainage and embankment, road tunnel project longitudinal and transverse drain. hdpe bellows specification, hdpe corrugated pipe prices, hdpe double wall corrugated pipe
