HDPE Hollow Wall Pipe | Smooth Inner ，Outer Wall, Low Fluid Resistance | Haierde

Produced from black HDPE via hot spiral winding molding.

Rectangular hollow ribs are arranged between the neat inner and outer walls, delivering outstanding hydraulic performance. Widely applied to municipal rainwater-sewage diversion, residential community drainage, park pipe networks, rural drainage, and pipelines under medium backfill or light-duty vehicle roads

Advantages of Haierde HDPE Hollow Wall Pipe

  • Hollow structure & high compression resistance: Reinforced hollow structure resists deformation and oval collapse under deep backfill, pedestrian roads and light-duty lanes, making up for weak compression resistance of thin-wall pipes.
  • Seamless smooth inner wall & low friction: Smooth inner wall reduces water resistance, improves drainage efficiency and avoids dirt adhesion; pipe diameter will not shrink after long-term use, solving poor drainage performance of traditional pipes

Why Choose Haierde HDPE Hollow Wall Pipe?

  • National standard quality guarantee: Strictly implements GB/T 19472.2 with full inspection for all finished products before delivery
  • Direct supply of full specifications: Modern production lines with sufficient stock for regular sizes, custom non-standard dimensions available.

Frequently Asked Questions

Q1: Differences between hollow wall pipe (Type A structured wall pipe) and double-wall corrugated pipe?

A:  Hollow wall pipe features higher overall structural strength, solving insufficient ring stiffness and weak stability of large-diameter double-wall corrugated pipes, with better performance in deep burial and heavy-load road sections.

Q2: Differences from HDPE winding pipe (Type B)?

A: Lower price and higher cost performance, solving the problem of high cost of structured wall winding pipes for small and medium diameters.

Q3: Which ring stiffness grade to choose for community roads and municipal arterial roads?

A: SN8 for non-motorized lanes inside communities with backfill within 2 meters; SN12.5 and above for municipal motor vehicle arterial roads, heavy-load factory areas and backfill over 3 meters.
