1. Filament Winding Process

The filament winding process involves wrapping continuous fibers (rovings) around a mold and impregnating them with resin. The winding angles can be adjusted based on pressure requirements to ensure optimal strength.

Advantages:

  • Reduced Wall Thickness: Optimal fiber orientation allows for thinner walls without compromising strength.

  • High Chemical Resistance: A flexible chemical protection layer effectively handles chemical stress.

  • Cost-Efficiency: An economical alternative to materials like rubber-lined steel.

2. Centrifugal Process

Exclusive to Fiberpipe, the centrifugal process involves introducing fiberglass into a rotating mold and saturating it with resin. This technique produces an exceptionally smooth inner and outer surface and delivers unmatched chemical resistance.

Advantages:

  • Superior Temperature Resistance: Complete resin saturation provides maximum strength and temperature resilience.

  • Minimized Flow Loss: A smooth inner wall ensures highly efficient flow rates.

  • Maximum Chemical Resistance: Specially selected resins optimally protect pipes from aggressive media.
