Hydrostatic Pressure Testing of FRP Vessels & Piping: BS 4994 & ASTM D3299 Inspection Protocols
The Necessity of Hydrostatic Testing for FRP Equipment Unlike homogeneous ductile metals, Fiberglass Reinforced Plastics (FRP) are anisotropic composite structures whose integrity relies on resin cure completeness, fiber-to-resin ratio, interlaminar bonding, and flawless nozzle fabrication. Hydrostatic testing is the definitive non-destructive proof test executed prior to commissioning chemical storage tanks, reaction vessels, and process piping. […]
