Flange guards (also known as flange shields, spray shields or pipe safety guards) are protective covers designed to wrap around pipe flange joints and connections. Their main purpose is to intercept and contain accidental spray-outs, leaks or mists of hazardous or corrosive fluids at flanged connections. Flange joints are a common weak point in piping systems (especially where high pressure, corrosive fluids, or high temperature flows exist).
