Spiral Structured Wall HDPE Pipe

SPIRAL HDPE PIPE produces a spirally wound structured wall pipe manufactured from PE-HD known as SPIRAL StructuredWallHDPE Pipe. It is available in diameters ranging from 400mm to 3500mm.

The SPIRAL Structured Wall HDPE Pipe system is economical and competitive, as the structured wall concept creates a pipe with superior ring stiffness while using considerably less raw material than conventional solid-walled thermoplastic pipes of equal stiffness.

A wide range of profile sizes and winding pitches are available for almost all requirements in any type of soil condition.

Product range as follows

  • Spiral Structured Wall HDPE Pipe from 400mm to 3500mm in ID with integral socket & spigot
  • Manholes from 400mm to 3500mm in ID
  • Fabricated tanks from 400mm to 3500mm in ID
  • Our tanks are all custom fabricated according to the client’s specifications
  • Stubs from 110mm to 1000mm

Manufacture Spiral Pipes

In the manufacture of SPIRAL Structured Wall HDPE Pipe a specially designed inner liner is wound upon a heated rotating mandrel. A hollow extruded rectangular profile is then wound over the inner liner and intimately bonded to it. This innovative wall construction uses geometric efficiency to maximize ring stiffness.

A wide range of profile sizes and winding pitches are available for almost all requirements in any type of soil condition. Because the pipe is manufactured on a mandrel, the internal diameter remains constant for each nominal size, irrespective of wall profile or thickness. The versatile nature of HDPE permits custom fabrication of bends, tees, and manhole units to complement the pipes, as well as corrosion-resistant tanks to meet a wide range of applications.
