Failure of Stainless Steel Check Valve in Oxygen Service

Source

Past fires in check valves in oxygen service have yielded clear internal damage. In a recent failure, most of the valve internals, including polymers, were undamaged and evidence of fire was confined to an O-ring and groove that was downstream of threads. An apparent key causal factor was evidence of silicone grease present.
