Double wall corrugated pipe application

HDPE double wall corrugated pipe
The double-wall corrugated pipe is formed by sintering and extruding the corrugated outer wall and a smooth inner wall simultaneously extruded by HDPE. The section of the pipe wall is a double-layer structure, the inner wall is smooth and flat, and the outer wall is equirectangularly arranged with a trapezoidal hollow structure. Pipe. It has excellent ring stiffness, good strength and toughness, light weight, strong impact resistance, not easy to break, etc., and it is easy to transport and install. The pipeline is mainly connected by rubber ring socket (also can be connected by heat shrinkable tape). Due to the special design of the wall structure of the double-wall corrugated pipe, under the condition of the same diameter and the same ring stiffness, the material (HDPE) is the least.

Product specifications are:
DN40, DN50mm, DN63mm, DN75mm, DN90mm, DN110mm, DN125mm, DN150mm, DN220mm, DN225mm, DN250mm, DN300mm, DN400mm, DN500mm, DN600mm, DN700mm, DN800mm, DN1000mm, DN1200mm, etc.
