HDPE large-diameter corrugated pipe diameter 200 and 300 factory hot.

Large-diameter double-wall corrugated pipe, large diameter pipes, large diameter outfall pipe is a new type of light. Is a high-density polyethylene as the main raw material, are jointly extruded from inside and outside the extruder, forming a smooth inner wall, an outer wall is trapezoidal corrugated wall has a hollow layer sandwiched between the inner and outer wall of the plastic pipe. Products with high stiffness, high pressure resistance, toughness, corrosion resistance, light weight, sound damping, high UV stability, long life, good flexibility, impact strength. It can be laid in poor geological section, and sealing, and construction speed. Widely used in municipal renovation project, construction, industrial and agricultural threading drainage, agricultural irrigation, sewage treatment works and other fields. Cement pipe, cast iron pipe, ductile pipe, steel pipe and other materials the best alternative. Large-diameter double-wall corrugated tube specifications: Nominal (inner diameter / outer diameter): φ90 / 104mm, φ93 / 104mm, φ95 / 110mm, φ100 / 110mm, φ125 / 135mm, φ200 / 208mm, φ300 / 310mm, φ400 / 416mm /, φ500 / 518mm, φ600 / 628mm, φ700 / 732mm, φ800 / 836mm. Large-diameter double-wall corrugated pipe characteristics: 1, the unique structure, strong compression capability; 2, smooth wall, over flow; 3, easy product links, interfaces sealed, corrosion-resistant, zero penetration, without fouling, avoid two secondary pollution, is the ideal "green pipe" 4, the product has a good flexural properties can be adapted to uneven soil subsidence; 5, long life, buried using up to 50 years; 6, light weight construction convenience, can reduce construction costs, shorten the construction period; 7, at a speed of 15 ft / sec 3-5 times higher than normal wear or fine steel. 4 large-diameter double-wall bellows Applications 1, municipal engineering rainwater and sewage discharge 2, mine ventilation, drainage works 3, industrial wastewater, residential drainage works 4, 5 agricultural irrigation, communication cables, cable sheathing, electrical cable protection sleeve 6, drilling engineering wall pipe (perforated wall corrugated pipe) 7, Salt Brine, water fishery
