HDPE drain pipe is an environmentally friendly drainage pipe produced by extrusion molding process with high density polyethylene (HDPE) as raw material. The product has good corrosion resistance, impact resistance, ring stiffness, and can adapt to various buried conditions such as municipal drainage, community sewage, road rainwater discharge, etc. It is an ideal substitute for traditional cement pipes and cast iron pipes. The inner wall of the pipe is smooth, non-scaling, and does not breed bacteria. Long-term use will not affect the drainage smoothness, in line with municipal and environmental safety requirements.

HDPE drain pipe is light in weight, good in toughness and convenient in construction, which can effectively reduce transportation and installation costs. The pipeline adopts hot-melt docking, electrofusion connection and other methods, and the interface has strong sealing and no leakage, which effectively avoids sewage leakage and pollution of groundwater sources. At the same time, the pipe material is acid and alkali resistant, aging resistant and wear resistant. It can be used stably for a long time in complex soil environment. The service life can reach more than 50 years. It greatly reduces the frequency of later maintenance and replacement and improves the overall economy of the pipe network.

HDPE drainage pipes are widely used in a wide range of applications, mainly for municipal rainwater drainage, urban sewage pipe network, residential community sewage, industrial park drainage, road rainwater drainage and other projects. The product specifications are complete and the ring stiffness grades are rich, which can meet the use needs of different covering depths and different load conditions. With the advantages of safety and environmental protection, stability and durability, and efficient construction, it has become one of the most commonly used plastic pipes in modern drainage and sewage systems.

• Strong resistance to chemical corrosion, suitable for complex sewage media

  Resistant to acid, alkali, oil, organic matter, microbial corrosion, hydrogen sulfide corrosion, and not easy to scale and block;

  Comply with GB/T 19472, ISO 4433, ASTM D1693, EN 12573

• High toughness and anti-settlement, adaptable to complex municipal geology

  Elongation at break ≥800%, excellent flexibility, and can withstand uneven settlement of foundation and soil displacement;

  Comply with ISO 13479, EN 1046

• The inner wall is smooth and low friction, smooth drainage and not easy to accumulate

  The inner wall roughness is ≤0.007mm, and the water flow resistance is small, which improves drainage capacity and reduces sludge adhesion;

  Comply  with AWWA M55, ISO 10838

• Ring stiffness is available in a wide range of options and has strong pressure-bearing and external pressure resistance capabilities.

  Multiple specifications of ring stiffness SN4-SN16 are available, which can meet the requirements of buried heavy load and deep soil covering construction;

  Comply with GB/T 19472.2, ISO 9969

• Hot melt integrated connection, excellent sealing and anti-seepage effect

  Hot melt/electrofusion connection, the interface strength is higher than the pipe body, preventing sewage leakage from contaminating soil and groundwater;

  Comply with DVS 2207, EN 12814

• Low temperature resistance and aging resistance, long-term stability for outdoor burial

  Long-term use temperature-40℃～60℃, good weather resistance, UV resistance and soil aging resistance;

  Comply with ASTM F714, GB/T 18252

• Convenient and efficient construction, suitable for trenchless construction

  It can be coiled, directional drilled, and dragged for pipe construction, reducing road excavation and municipal construction costs;

  Comply with GB 50268, ISO 10460

• The weight is easy to transport and install, and the overall cost is lower.

  The dead weight of the pipe is only 1/8 of the concrete pipe and 1/7 of the steel pipe. It is easy to transport and install, greatly shortening the construction period.

• Ultra-long service life and low post-operation and maintenance costs

  The designed service life of buried working conditions is ≥50 years, with no need for anti-corrosion and less maintenance, reducing long-term operation and maintenance investment;

  Comply with GB 50235, AWWA C906
