HDPE double-wall bellows HDPE double wall corrugated pipe Description Description: DPE double wall corrugated pipe is a high density polyethylene as the main raw material, double-wall corrugated pipe 200, respectively, by the inner and outer extrusion, double wall corrugated pipe 600, time molding the new lightweight pipes, wall smooth, 800 double-wall corrugated pipe, corrugated outer trapezoid, inside and outside wall of the hollow layer sandwiched intramural, its unique design makes these pipe wall has a ring stiffness, light weight, high pressure resistance, toughness, corrosion resistance and other characteristics. It can be laid in poor geological section, and sealing, and construction speed. HDPE double wall corrugated pipe ring stiffness according to classification can be divided into two kinds of S1 and S2 type, pipe length of 6 m / root; divided according to the following standard specifications (nominal diameter) DN200 mm, DN300 mm, DN400 mm, DN500 mm , DN600 mm, DN800 mm, DN1000 mm, DN1200mm. Through the wall bellows HDPE plastic HDPE double-wall corrugated metal pipe pipeline repair points 1, HDPE double wall corrugated pipe after pipe laying, due to unexpected factors causing partial damage to the wall, double wall corrugated pipe, when damaged parts of the area or crack The length and width does not exceed a predetermined, remedial measures can be taken paste .2, HDPE double wall corrugated pipe wall of the hole diameter or partial damage to the edges grow in 20mm, the available PVC adhesive paste solvent in its external diameter not l00mm and the pipe is less than the same material .3 circular plate, the wall cavities 20 to local damage when 100mm, available PVC solvent bonding paste is not smaller than the maximum size of the hole and the pipe plus l00mm same material at its outer circular board double-wall corrugated pipe 800, through plastic (certified), double-wall bellows made of gold on Xiongxian plastic products Limited provide gold. Plastic products Limited (www.jinshangtongsj.com) on gold Xiongxian Hebei Baoding, composite pipe leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. On gold-plastic leadership with the staff warmly welcome all inquiries negotiations to create the gold-plastic better future.
