Centrifugal casting

Centrifugal casting of pipe ranging from 25 mm/1 inch to 356 mm/14 inches in diameter is an alternative to filament winding for high-performance, corrosion-resistant service.

Centrifugal casting of pipe ranging from 25 mm/1 inch to 356 mm/14 inches in diameter is an alternative to filament winding for high-performance, corrosion-resistant service. In cast pipe, 0°/90° woven fiberglass provides both longitudinal and hoop strength throughout the pipe wall and brings greater strength at equal wall thickness compared to multiaxial fiberglass wound pipe. In the casting process, epoxy or vinyl ester resin is injected into a 150-G centrifugally spinning mold, permeating the woven fabric wrapped around the mold’s interior surface. The centrifugal force pushes the resin through the layers of fabric, creating a smooth finish on the outside of the pipe, and excess resin pumped into the mold creates a resin-rich corrosion- and abrasion-resistant interior liner.
