Is the 90° Elbow, BSPT Male Thread, Cast Iron, Type 94/94 rated for continuous use at +300°C and what are the maximum allowable pressures at that temperature?

90° Elbow, BSPT Male Thread, Cast Iron, Type 94/94 Format — Yes. The fitting is rated for continuous use at temperatures up to +300°C. Maximum allowable working pressures: 25 bar up to +120°C; 20 bar up to +300°C.

Can the 90° Elbow, BSPT Male Thread, Cast Iron, Type 94/94 be used with steam systems, and what precautions are required at elevated temperatures and pressures?

Yes — the 90° Elbow, BSPT Male Thread, Cast Iron, Type 94/94 can be used with steam systems within its rated temperature and pressure limits. It is engineered for temperatures up to +300°C and withstands working pressures of 25 bar up to +120°C and 20 bar up to +300°C, which covers many steam-service conditions. Precautions: - Do not exceed the stated pressure/temperature ratings: above +120°C allowable pressure reduces from 25 bar to 20 bar; at temperatures approaching +300°C ensure system pressure stays ≤20 bar. - Account for thermal expansion and support piping to avoid undue stress on threaded joints and the elbow. - Use appropriate thread sealing methods and steam-compatible sealants or PTFE tape rated for the temperature to ensure leak-free joints. - Protect against water hammer and pressure spikes (use slow-opening valves, steam traps, and pressure-relief devices) to prevent shock loads that can damage cast iron fittings. - Inspect for corrosion and degradation regularly; condensate and wet steam can accelerate wear—drain condensate and maintain dry steam where possible. - Consider vibration isolation and avoid mechanical shock; cast iron is strong but less ductile than steels at high cyclic loads. - If operating near maximum limits or under cyclic thermal/pressure loading, consult the system engineer or supplier for suitability or consider higher-grade materials (e.g., steel) for enhanced safety. Following these precautions will help ensure safe, reliable service of the 90° Elbow, BSPT Male Thread, Cast Iron, Type 94/94 in steam applications.
