Inconel 690 ASTM B366 45 / 90 / 180 Deg Elbow Buttweld Fitting

ASTM B366 Inconel 690 45 / 90 / 180 Deg Elbow


ASTM B366: The specification covers forged or rolled nickel and nickel alloy fittings (including elbows, tees, reducers, etc.), suitable for high temperature, high pressure and highly corrosive fluid systems.

ASTM B366 Inconel 690 elbows are core connectors for nuclear power, high temperature caustic and high chlorine industrial pipelines. Their high chromium content and nuclear grade stability are irreplaceable in steam generator systems. When selecting, strictly follow the ASME III or RCC-M specifications and evaluate alternatives in reducing acid environments. It is recommended to conduct corrosion tests for working conditions and give priority to solution + stabilization heat treatment process to extend service life.
