  HDPE double-wall corrugated pipe is a new type of lightweight pipe made of high-density polyethylene. It has the characteristics of light weight, good initial performance, fast construction, and long life. Compared with the pipe material, the cost is greatly reduced. And because the connection is convenient and reliable, it is widely used at home and abroad.
  Product Introduction
  GB/T19472.1-2019 "Polyethylene (PE) Structural Wall Piping System for Buried Part 1: Polyethylene Double-wall Corrugated Pipe" National Standard of the People's Republic of China.
  Product use
  1. Municipal drainage and sewage pipeline system engineering
  2. Underground drainage and sewage in apartments and residential quarters
  3. Pre-buried pipelines in expressways, underground seepage pipe network in golf courses
  4. Water conservancy projects such as farmland irrigation and water delivery and drainage
  5. Chemical industry , Mine is used for fluid transportation and ventilation, etc.
  Product features
  1. Strong external pressure resistance: the outer wall has a ring-shaped corrugated structure, which greatly enhances the ring stiffness of the pipe, thereby enhancing the pressure bearing capacity of the pipe to the soil load.
  2. The molding process is mature and stable: it is hot extrusion, integrated molding, no welding marks, and high sound generation efficiency.
  3. Good impact resistance at low temperature: The embrittlement temperature of HDPE double-wall corrugated pipe is -10°C, which has excellent impact resistance.
  4. Good chemical stability: Since HDPE molecules have no polarity, the chemical stability is excellent. Except for a few strong oxidants, most chemical media will not damage it.
  5. Convenient connection: It adopts socket/sealing ring connection, which is convenient, fast, safe and reliable, and avoids the influence of artificial, weather and environmental factors.


  The connection method of HDPE double-wall corrugated pipe can be divided into three steps, as follows:
  1. Before the socket, first check whether the specifications of the rubber sealing ring are in line with the supporting products, intact and elastic. The rubber seal should be installed in the groove between the second and third crests of the socket. The sealing ring must be straightened out and installed flat, and its installation quantity should be determined according to the relevant design requirements. If two sealing rings need to be installed, they can be placed at intervals of one corrugation.
  2. When connecting, first clean the inner wall of the HDPE double-wall bellows socket, and apply lubricant on the inner wall of the socket and the rubber ring of the HDPE bellows socket, and then align the central axis of the end face of the socket.
  3. The interface method should be carried out according to the following procedures: DN400 and below pipes, first, one person hangs the socket of the installed HDPE double-wall corrugated pipe with a cotton rope, and the other person inserts a long crowbar into the foundation obliquely, and resists the double-wall corrugated pipe The horizontal baffle at the center of the end of the pipe, and then slowly insert the HDPE corrugated pipe into the socket of the HDPE double-wall corrugated pipe to be installed to the predetermined position: PE pipes above DN400 can be pulled by two lever hoists. bit. When the joints are closed, the lever hoists on both sides of the pipe joint should be pulled synchronously so that the rubber sealing ring is in place correctly without twisting or falling off.
