Spiral HDPE Pipe manufactures a spirally wound structured wall pipe from PE-HD, known as SPIRAL Structured Wall HDPE Pipe. The SPIRAL Structured Wall HDPE Pipe system is economical and competitive, as the structured wall concept creates a pipe with superior ring stiffness, utilizing considerably less raw material than conventional solid-walled thermoplastic pipes of equal stiffness. HDPE/PP profiled spiral wound pipe systems, available in various stiffness classes, are designed for utility and industrial applications. These pipes are made from high-density Polyethylene (HDPE) or Polypropylene (PP). The diameter of the HDPE/PP Profile pipe ranges from DN/ID 300mm to DN/ID 3400mm. The ring stiffness options include SN2, SN4, SN8, SN16, or can be customized according to customer requirements.
