The HDPE Double Wall Corrugated Drain Pipe is a classic buried drainage and sewage pipe processed by one-time extrusion molding of high-density polyethylene (HDPE) with advanced double-wall corrugated forming technology. As the core supporting product of the municipal drainage pipe network, it is the first choice for medium and small-diameter branch and secondary trunk pipelines, and forms a perfect complementary system with the HDPE Hollow Wall Winding Drain Pipe for large-diameter trunk projects. With mature production technology, high cost performance and excellent hydraulic performance, this pipe is widely used in urban and rural decentralized drainage projects. Its unique double-wall corrugated structure balances structural strength and lightweight design, and the smooth inner wall ensures unobstructed water flow, effectively reducing pipe sedimentation and later maintenance costs. It is a cost-effective and reliable choice for modern municipal, residential and industrial branch drainage pipe network construction.

High cost performance with mature technology: The one-time extrusion molding process has high production efficiency and stable product quality, and the price is more competitive, which is suitable for large-scale laying of municipal branch pipe networks.
Full coverage of medium and small-diameter specifications: Conventional specifications from DN110 to DN1000mm fully meet the drainage needs of municipal branch pipes, residential communities and industrial park branch pipelines, with strong matching.
Corrugated structure with excellent impact resistance: The outer corrugated and inner smooth double-wall structure distributes stress evenly, and the pipe body has strong impact resistance and anti-deformation performance, adapting to general construction and geological conditions.
Ultra-fast installation and construction: The rubber ring flexible socket connection realizes quick plug-in installation, no need for complex welding equipment, which shortens the construction period by more than 50% compared with concrete pipes and reduces labor costs.
Superior hydraulic performance: The ultra-smooth inner wall with a Manning roughness coefficient of 0.009 reduces water flow resistance and sedimentation, ensuring high flow efficiency and greatly lowering later dredging and maintenance costs.
Strong environmental adaptability: The virgin HDPE material has excellent anti-aging, corrosion and low-temperature resistance, and can be used stably in open-air storage and buried laying environments without additional protection.
Flexible laying for small space: The pipe body has a certain flexibility and can be naturally bent at a small angle, adapting to non-linear pipeline routes and narrow construction spaces such as residential communities and green belts.
Green and recyclable: No toxic and harmful substances are released during production and use, and the pipe can be recycled and reprocessed after scrapping, in line with national green environmental protection engineering standards.
The HDPE Double Wall Corrugated Drain Pipe is specially designed for medium and small-diameter, low to medium flow drainage projects, and its application scenarios cover all aspects of urban and rural drainage pipe networks: municipal rainwater and sewage branch pipes in residential areas and urban back streets; daily domestic sewage and stormwater drainage pipes for residential communities and commercial districts; industrial wastewater branch discharge pipes for industrial parks and economic development zones; drainage pipe networks for urban and rural combination areas and new rural construction; garden greening and square rainwater collection and drainage pipes; underground garage and basement rainwater and sewage discharge pipes; and secondary trunk drainage pipes for small municipal engineering and campus construction.
Our HDPE Double Wall Corrugated Drain Pipe is produced with 100% virgin HDPE raw materials, and all products comply with national and international drainage pipe quality standards. The automated extrusion molding production line ensures consistent product size and performance, and each pipe is subject to strict air tightness and ring stiffness tests before leaving the factory. We provide targeted customized solutions for different engineering needs, including customized ring stiffness grades (SN12.5), special length pipes and food-grade raw material pipes for special water supply and drainage projects. In addition, we have a perfect pre-sales and after-sales service system, providing professional on-site construction guidance and technical support, and the short production cycle can meet the urgent supply needs of various engineering projects, balancing quality, cost and construction efficiency for customers.
A1: The main installation method is rubber ring flexible socket connection, which can be completed by simple manual operation without complex welding equipment, and is very suitable for on-site quick construction, especially for the narrow construction space of residential communities.
A: Yes, the lightweight design and small-diameter specifications are perfectly adapted to the garden greening drainage needs, and the corrosion resistance of HDPE material can avoid pipe damage caused by soil and fertilizer corrosion, with a long service life.
A: This pipe is mainly used for medium and small-diameter branch and secondary trunk drainage pipelines with low flow and shallow burial depth; while the HDPE Hollow Wall Winding Drain Pipe is suitable for large-diameter trunk drainage pipelines with high flow, deep burial and heavy-load conditions, and the two form a complementary drainage pipe network system.
