Wanfang trenchless high density polyethylene (HDPE) solid wall drain pipe is a kind of flexible pipe with smooth inner and outer walls, which is made of HDPE by extrusion and vacuum molding. In recent years, the trenchless technology of pipeline is called "minimally invasive surgery" in the city. It can minimize the impact of construction and is a safe and effective construction method for environmental protection. With the advantages of reliable connection, long service life and good impact resistance, Wanfang trenchless HDPE solid wall drainage pipe is suitable for areas where excavation cannot be carried out and meets the upgrading requirements of modern life pipeline network.
(urban construction industry standard) high density polyethylene drainage pipe for trenchless laying CJ / 0358-2010
Key words: Construction friendly, connection safe, aging resistant and impact resistant
1. No damage to the subgrade surface construction friendliness: during the construction process, the non excavation HDPE solid wall drainage pipe of ten thousand square meters can be constructed without damage to the subgrade surface, which greatly reduces the impact of the construction process on the residential environment of nearby residents.
2. Reliable connectivity: the strength of PE pipe hot-melt or electric fusion interface is higher than that of the pipe body, and the joint will not be disconnected due to soil movement or live load.
3. The trenchless HDPE solid wall drainage pipe of Wanfang is excellent in stress cracking resistance, chemical corrosion resistance, low temperature impact resistance, etc. It has a long service life. Under the rated temperature and pressure, the service life is up to 50 years. Greatly reduce the number of pipeline maintenance and replacement, and effectively control the operation and maintenance cost of the project.
4. It has good impact resistance. PE pipe has good toughness and high impact resistance. Heavy objects directly press on the pipe, which will not lead to pipe rupture.
5. Good constructability. The tube material is light and the welding process is simple.
