PE Double-wall Corrugated Pipe
PE Double-wall Corrugated Pipe
PE double-wall corrugated pipe is mainly made from polyethylene via extrusion process and special moulding process. The inner wall is very smooth while the outer wall is corrugated. It’s a new type of light-weighted wall pipe.
This product was developed and manufactured in Germany in the early 1980’s for the first time and has developed from a single species to complete products series after a decade of development and improvement. At present, its production process and technology are pretty mature. Because of its excellent performance and relatively economical cost, it has been greatly popularized and applied in Europe and other developed countries. In our country, the promotion and application of PE double wall corrugated pipe is in the rising phase. The product has already tested by the National Chemical Building Materials Testing Center, and the results showed that various technical indicators reached application standard.
PE double-wall corrugated pipe has the advantages of light weight, high pressure resistance, good toughness, high speed during construction and long service life. Other than the good corrosion resistance and high insulation, smooth inner wall, small flow resistance and other characteristics of the ordinary plastic pipe, it also have excellent ring stiffness, good strength and toughness, light weight, strong impact resistance and would be difficult to be damaged because of the use of a special ring hollow structure. At present, it has been widely used in many fields in the developed countries, especially the United States, Canada, Japan and many European countries. PE double-wall corrugated tube is also widely used in municipal drainage and sewage, agricultural irrigation, mine ventilation, chemical industries, communication cable sheathing and other fields. Practice has proved that under the condition of meeting the requirements of strength and stiffness for the engineering application, the double-wall corrugated pipe structure can save 30% - 50% of raw materials. In addition, compared with the concrete pipe, cast iron pipe, it has the advantages of convenient transportation and installation, reducing labor intensity of construction personnel and reducing the total investment of the project and other advantages. PE double-wall corrugated tube has become the first choice of "plastic steel” pipeline industry. It overcomes the shortcomings of the concrete pipe and cast iron pipe, which are difficult installment, easy corrosion, large water flow resistance, easy breeding of bacteria, short service life and other shortcomings.
