HDPE reclaimed water and sewage pipes are made of PE100 high-density polyethylene and are produced by extrusion molding process. They are specially designed for water reuse, municipal sewage, domestic sewage, and industrial wastewater collection and transportation. They are resistant to acid and alkali, oil, and chemical corrosion. They can adapt to complex sewage medium environments for a long time and do not rust, scale, or breed microorganisms.

The inner wall of the pipe is smooth, the friction is small, the drainage is unobstructed and not easy to block, and the flow efficiency is higher than that of traditional pipes; the overall toughness is good, the anti-settlement and impact resistance, and the buried use can adapt to the deformation of the foundation and is not easy to break. The hot melt butt/electric fusion connection is adopted, the interface strength is higher than that of the pipe body, the seal is reliable, and the leakage is zero. It can effectively prevent sewage from polluting the groundwater, and the service life can reach 50 years.

It is widely used in municipal sewage pipe network, community water pipe network, industrial park sewage treatment, building drainage, rural sewage treatment and other projects, with light weight, fast construction and low comprehensive cost. It is an environmentally friendly and energy-saving pipe material that replaces cement pipes, cast iron pipes and steel pipes.

• 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
