SPIRAL HDPE PIPELINE SYSTEMS Applications for Long Term Reliability
Diameter: 300mm to 3,000mm (manufactured in Malaysia)
There is an increasing awareness of serious corrosion problems of conventional materials and growing concern about exfiltration problems are the main reasons for the application of our innovative, light, inert and large diameter SPIRAL high density polyethylene pipeline system.
SPIRAL pipe is manufactured through a specially designed profile extrusion process where an extruded profile strip is spirally wound over a mandrel. Overlap on the edge is fused homogeneously together while it is in the hot plastic state, producing a smooth internal surface.
SPIRAL pipe system offers a wide range of fittings and manholes, which are also manufactured by specially designed profile-extrusion process and fabricated by extrusion welding.
