PVC-U double-wall corrugated pipes were successfully developed and widely used in western developed countries in the early 1990s. With the rapid development of my country's urbanization and the country's further attention to environmental protection, PVC-U double-wall corrugated pipes will have a wide range of applications.
Material of PVC-U double-wall corrugated pipe：
The PVC-U double-wall corrugated pipe is made of hard polyvinyl chloride as the main raw material, and various plastic additives are added. It adopts the structural principle of a hollow ring and is extruded by a double screw machine. The section of the pipe wall is a double-layer structure, and the inner wall is smooth and flat. It is a pipe with a trapezoidal hollow structure whose outer walls are arranged equidistantly.
Features of PVC-U double-wall corrugated pipe：
Light weight, convenient handling and unloading: The PVC-U pipe is light in material, convenient for handling, handling and construction, so the overall cost is low.
Excellent corrosion resistance: PVC-U pipe has excellent acid resistance, alkali resistance, and corrosion resistance, and is very suitable for use in the chemical industry.
Low fluid resistance: The inner wall of the PVC-U pipe is smooth, its frictional resistance is small, and the fluid resistance is small. Compared with concrete, the pipe diameter of PVC-U pipe can be reduced under the same flow rate.
High mechanical strength: PVC-U pipe has good water pressure resistance, external pressure resistance, impact resistance, etc. It is suitable for piping projects under various conditions.
Good connection tightness: PVC-U pipe adopts elastic sealing ring socket connection, and the connection tightness is better than metal pipe and concrete pipe.
Longer service life: PVC-U pipe has strong abrasion resistance, so it has a long service life.
