Product Introduction
The Introduction of HDPE Double Wall Corrugated Pipe for drainage
High-density polyethylene (HDPE) double-wall corrugated pipe is a new type of pipe with a ring-shaped outer wall and a smooth inner wall. It was first developed in Germany in the early 1980s.
After more than ten years of development and improvement, it has evolved from a single variety to a complete product line. At present, the production process and the use technology are very mature. Due to its excellent performance and relatively economical cost, it has been greatly promoted and applied in developed countries such as Europe and the United States.
In China, the promotion and application of HDPE double-wall corrugated pipe is in the rising stage, and all technical indicators have reached the use standard. The color of the inner wall of the double-walled bellows is usually blue and black, and some brands use yellow on the inner wall.

The Connection mode of HDPE Double Wall Corrugated Pipe for Drainage
Bearing interface seal connection
HDPE double-wall corrugated pipe adopts double-layer pipe wall to make the pipe wall harder.
①It is connected with natural rubber ring.
When connecting, keep the socket clean and clean, and insert it horizontally.
The installation is convenient, the connection is reliable, the leakage is not easy, the comprehensive cost is low, and the service life is up to 50 years.
