Product Overview

Large diameter HDPE pipe manufactured from PE100 for trunk water mains and industrial applications. High flow capacity and low friction loss make it an economical choice for major transmission lines. Spanning DN315 to DN2000, this HDPE large diameter pipe replaces steel and concrete mains with a single lightweight, corrosion-free PE100 line that ships in long lengths to minimize field joints.

Key Features

  • High Flow Capacity: The large smooth bore of the HDPE large diameter pipe maximizes flow and minimizes head loss.
  • Light Weight: The HDPE large diameter pipe is much lighter than steel or concrete pipe of equal diameter, reducing handling cost.
  • Long Lengths: Fewer joints mean faster installation and lower leak risk on long mains of HDPE large diameter pipe.
  • Long Service Life: The HDPE large diameter pipe offers a 50-plus-year design life in water supply service.
  • PN6 – PN16 Ratings: The HDPE large diameter pipe is available in SDR21, SDR17 and SDR11 to match transmission pressure.
  • DN315 – DN2000 Coverage: The HDPE large diameter pipe covers district mains through raw-water transmission lines.

Production

Raw Material

The HDPE large diameter pipe is extruded from certified PE100 black compound compliant with ISO 4427.

Extrusion Process

The HDPE large diameter pipe is manufactured on large-diameter extrusion lines with controlled cooling for uniform wall thickness.

Quality Control

Each HDPE large diameter pipe is tested for ovality, wall thickness and hydrostatic pressure before release.

Applications

  • Municipal trunk water mains use the HDPE large diameter pipe for high-volume district transmission.
  • Raw water transmission from reservoirs and rivers installs the HDPE large diameter pipe for low-loss transfer.
  • Large industrial piping and cooling water lines rely on the HDPE large diameter pipe for corrosion-free flow.
  • Power plant cooling and desalination intake lines choose the HDPE large diameter pipe for long-life large-bore service.
