BAIJIAN - Third party testing organization
High density polyethylene (HDPE) double wall corrugated pipe is a new type of pipe with a circular structure outer wall and a smooth inner wall. It was first developed in Germany in the early 1980s. After more than ten years of development and improvement、 it has evolved from a single variety to a complete product series. The production process and usage technology are already very mature. Due to its excellent performance and relatively economical cost、 it has been greatly promoted and applied in developed countries such as Europe and America. In China、 the promotion and application of HDPE double wall corrugated pipes are in an upward trend、 and all technical indicators have met the usage standards. The inner walls of double walled corrugated pipes are usually blue and black in color、 with some brands using yellow for the inner walls. Process characteristics: Digital centralized control of the entire line、 dual machine co extrusion、 double layer separation、 full vacuum covered belt feeding、 random expansion、 one-time forming of HDPE double wall corrugated pipes. Product specifications: DN110mm、 DN125、 DN150、 DN220、 DN225mm、 DN250、 DN300mm、 DN400mm、 DN500mm、 DN600mm、 DN700mm、 DN800、 DN1000、 DN1200、 and other specifications. The advantages of double wall corrugated pipes include reasonable structure、 beautiful appearance、 temperature resistance -40 ℃ -60 ℃、 and low resistance、 Large flow rate、 strong flame retardancy、 long service life、 reliable hygiene performance、 low comprehensive cost、 acid alkali resistance、 corrosion resistance、 high strength、 strong seismic performance、 energy conservation and consumption reduction、 convenient installation and transportation
