The CFW plant produces Glass Reinforced Plastic (GRP) pipes and sleeves from sizes 300 mm dia upto 2600 mm dia.


The plant is fully computer controlled, based on the continuous filament winding process, fully in compliance with A.S.T.M. code D 2996 (Standard Specification for Filament Wound Reinforced, Thermosetting Resin Pipes) type 1, grade 2, class E, and ASTM D3517, ASTM D3754, ASTM D3262, BS 5480:1990, AWWA C950, AWWA Manual M45, EN standards and ISO 10639.

Manufacturing process

The manufacturing of a continuous pipe or a sleeve blank is carried out on a mandrel formed by winding a continuous steel band over horizontal beams provided with supporting discs sized according to the diameter of the pipe required. The steel band moves in the axial direction sliding over the ball bearings inserted in beam grooves. At the end of the mandrel, the steel band is guided by an exit head into the mandrel inner tube, which supports the exit head. On the opposite end of the mandrel near the cam, the steel band is wound on the mandrel again. In this way the steel band forms a smooth surface mandrel with simultaneous advancing in the axial direction.
