B-type polyethylene clade drainage pipe is a large-diameter buried drainage pipe mainly made of high-density polyethylene (HDPE) and produced through hot winding molding process. The pipe adopts a double-layer wall and ring-shaped reinforced structure design, with high ring stiffness and strong pressure bearing capacity, which can effectively resist external loads and geological deformation, and is suitable for various complex underground pipeline environments.

The inner wall of the pipe is smooth, the water flow resistance is low, the drainage efficiency is high, it is not easy to scale or block, and it can operate stably for a long time. The product has the characteristics of corrosion resistance, aging resistance, acid and alkali resistance, long service life, good overall flexibility, strong settlement resistance, can adapt to slight deformation of the foundation, is not easy to break, does not leak, and is an ideal substitute for traditional cement pipes and steel pipes.

B-type polyethylene clade drainage pipe is lightweight, easy to transport, and simple to construct. It adopts flexible socket connection, with high installation efficiency and good sealing performance. Widely used in municipal rainwater and sewage drainage, residential area sewage discharge, industrial park pipeline network, road drainage, water conservancy and other projects, it is the preferred drainage pipe for modern urban pipeline network construction, environmental protection engineering and infrastructure construction.

• B-type winding reinforced structure, ultra-high ring stiffness and compression resistance

  High-density polyethylene B-type carat tube is wound and formed, with SN8-SN16 high ring stiffness optional, resistant to heavy pressure from overburden, vehicle rolling, and soil extrusion, and is not easily deformed when buried deeply;

  Comply with GB/T 19472.2, ISO 9969, ASTM F894

• The whole body is wound and formed into one piece, with a stable structure and anti-settlement.

  Continuous heat winding process, the pipe has strong integrity and excellent flexibility, adapts to uneven settlement of the foundation and geological displacement, and resists fracture without cracking;

  Comply with EN 1046, ISO 13479

• The inner wall is smooth and flat, and the drainage and sewage discharge efficiency is high

  The inner wall roughness is ≤0.007mm, the water flow resistance is small, and sediment is not easy to accumulate. The large diameter can achieve large flow and rapid drainage;

  Comply with ISO 10838, AWWA M55

• Resistant to strong acid and alkali corrosion, suitable for complex drainage media

  Resistant to domestic sewage, industrial wastewater, soil salinity and microbial erosion, and will not age, scale or leak after long-term burial;

  Comply with ISO 4433, ASTM D1693, EN 12573

• Socket-type elastic sealing, reliable joint leakage prevention

  The rubber sealing ring is used for socket connection to adapt to thermal expansion and contraction and foundation deformation, and prevent sewage leakage from contaminating groundwater;

  Comply with EN 12814, GB/T 19472.2

• Large diameter and complete specifications, suitable for large municipal drainage projects

  It can produce ultra-large diameter pipes to meet the needs of large-flow drainage in urban trunk pipe networks, rainwater and sewage diversion, sponge cities, and river management.

• Light weight, good toughness, convenient and efficient construction

  The dead weight is lower than that of reinforced concrete pipes, and it is easy to transport and install. It can be quickly connected on site, shortening the construction period and reducing labor costs;

  Comply with GB 50268, ISO 10460

• Low temperature resistance, anti-aging, strong environmental adaptability

  ‑40℃～60℃ wide temperature range use, resistant to freezing and thawing, ultraviolet rays, salt spray erosion, can be stably used in severe cold areas in the north;

  Comply with ASTM F714, GB/T 18252

• Resistant to sand and gravel erosion and wear, stable long-term operation

  Resistant to the impact and wear of sewage impurities and backfill sand and gravel, the structure has long-lasting strength and is not easy to be damaged or collapsed.

• Environmentally friendly, recyclable, long service life and low operation and maintenance costs

  Non-toxic, non-polluting and recyclable, with a service life of ≥50 years under buried conditions, no need for anti-corrosion maintenance, and the overall cost is better than that of concrete pipes;

  Comply with GB 50235, AWWA C906
