HFW
Process

Dual Helical Filament Winding Process : (HFW Process)

The glass fibres are transported by means of supports to the resin tray where the glass will be impregnated by resin.

The impregnated glass will be applied on a rotating mandrel (mould) in a specified angle.

This process will continue until the required wall thickness is achieved. After the pipe is cured the pipe will be extracted from the mandrel, this can be done mechanically (i.e. Hydraulic pipe extractor)

The pipe is cut to required length. On the next station the pipe ends will be machined to create a joint configuration.
