High-density polyethylene (HDPE) Double Wall Corrugated Pipe, or simply PE corrugated pipe, is a new type of pipe with a ring-shaped outer wall and a smooth inner wall. HDPE Double Wall Corrugated Pipe was first successfully developed in Germany in the early 1980s. After more than a decade of development and improvement, it has evolved from a single product type to a complete product series. Currently, its production process and application technology are very mature.
Production process characteristics include digital and fully centralized control, dual-machine co-extrusion, double-layer diversion, full vacuum belt feeding, random flaring, and one-time molding.
The HDPE Double Wall Corrugated Pipe is a new type of lightweight structural wall pipe manufactured from high-density polyethylene (HDPE). It is designed with a dual-layer structure, combining a smooth inner wall for efficient flow and a corrugated outer wall for enhanced mechanical strength. This structure provides an optimal balance of performance, cost efficiency, and long service life.
The HDPE Double Wall Corrugated Pipe is widely recognized for its light weight, high pressure resistance, excellent toughness, fast installation efficiency, and long operational lifespan. Its advanced structural wall design significantly reduces material consumption and overall project cost compared to traditional pipe systems. Due to its reliable connection system and ease of installation, it is widely used in municipal, industrial, and infrastructure projects, gradually replacing conventional concrete and cast iron pipelines in many applications.
The HDPE Double Wall Corrugated Pipe is manufactured in strict accordance with GB 19472.1-2019 “Buried Polyethylene (PE) Structural Wall Piping Systems” to ensure consistent quality and performance.
Key specification details include:
These standardized classifications ensure the HDPE Double Wall Corrugated Pipe meets the requirements of different load-bearing conditions and engineering applications.
The HDPE Double Wall Corrugated Pipe is produced using advanced CNC-controlled automated production lines, ensuring high precision and stable quality output. The manufacturing process includes several key features:
This advanced production system ensures that each HDPE Double Wall Corrugated Pipe meets strict dimensional and performance requirements.
The corrugated outer structure significantly enhances ring stiffness, improving the pipe’s ability to withstand soil loads and external pressure. This makes the HDPE Double Wall Corrugated Pipe highly suitable for buried pipeline systems.
Under non-exposed conditions, such as protection from UV radiation, the service life can exceed 50 years. The material demonstrates excellent wear resistance, outperforming traditional steel pipes in abrasion resistance under tested conditions.
The HDPE Double Wall Corrugated Pipe maintains structural integrity at extremely low temperatures, with a brittleness temperature of -70℃. Construction can generally proceed without special protective measures in temperatures above -30℃.
The pipe exhibits excellent resistance to most chemical media except strong oxidizing agents. It is not affected by soil acidity or alkalinity and does not support bacterial growth or scaling, ensuring stable flow capacity over long-term use.
The smooth inner wall reduces flow resistance, allowing higher flow capacity compared to conventional pipes of the same diameter. This enables engineers to select smaller diameter HDPE Double Wall Corrugated Pipe while maintaining required flow performance.

The HDPE Double Wall Corrugated Pipe is widely used in urban infrastructure for drainage, sewage discharge, rainwater collection systems, water supply networks, and ventilation pipelines.
It is commonly used as protective conduits for power cables, optical fiber cables, and communication signal transmission systems, ensuring safe and durable underground installation.
Due to its excellent corrosion resistance, the HDPE Double Wall Corrugated Pipe is suitable for irrigation and drainage systems in farmland, orchards, tea plantations, and forestry zones, as well as industrial fluid transport environments.
The pipe is widely applied in railway, highway, golf course, and sports field drainage systems, including seepage and subsurface water management solutions.
