Is the Screw with 2 x BSP female thread, cast iron, type 330/48 suitable for continuous operation at 300Â°C and 20 bar pressure?

Yes. Screw with 2 x BSP female thread, cast iron, type 330/48 is specified for continuous operation up to +300Â°C with a working pressure rating of 20 bar at that temperature. The product description states operating temperature: up to +300Â°C and working pressure: 20 bar (up to +300Â°C), so it meets your stated conditions of 300Â°C and 20 bar. Ensure that installation, sealing materials, and connected system components are also rated for those conditions and follow applicable safety and maintenance procedures.

Can the Screw with 2 x BSP female thread, cast iron, type 330/48 be used with elastomer seals at temperatures up to 300Â°C?

No - Screw with 2 x BSP female thread, cast iron, type 330/48 cannot reliably use elastomer seals at temperatures up to 300Â°C. Although the couplingâs maximum operating temperature is up to +300Â°C, elastomer seals generally degrade well below that temperature. The product specifies flat sealing between internal components (metal-to-metal) and pressure ratings of 25 bar (to +120Â°C) and 20 bar (to +300Â°C), indicating design intent for high-temperature metal sealing rather than elastomers. Use high-temperature gasketing materials or metal/graphite seals rated for 300Â°C.

Does the Screw with 2 x BSP female thread, cast iron, type 330/48 require special installation for flat sealing at high temperatures?

Screw with 2 x BSP female thread, cast iron, type 330/48: Yes. special attention is required for flat sealing at high temperatures. The product description indicates flat sealing between internal components and an operating temperature up to +300Â°C. Standard flat gaskets or sealants suitable for low temperatures may degrade, creep or lose sealing force as temperature rises. For reliable sealing up to +300Â°C you should: - Use gasket materials rated for the intended temperature (e.g., graphite, PTFE-expanded only if rated to 300Â°C, or other high-temperature elastomers/graphite composites specified for 300Â°C). - Ensure proper surface finish and flatness of mating faces to avoid leaks under thermal cycling. - Consider thermal expansion: select sealing materials and assembly torque that accommodate differential expansion between ductile iron components and gasket. - Follow recommended torque values to achieve adequate compression without damaging gasket or threads; re-check torque after initial heat cycling if possible. - Avoid organic sealants that decompose at high temperature; prefer inorganic or high-temp engineered seals. - If pressure is near the 20â25 bar limits at elevated temperatures, verify combined temperature/pressure ratings of gasket and assembly. In summary, Screw with 2 x BSP female thread, cast iron, type 330/48 requires high-temperatureârated sealing materials and careful assembly practice to ensure reliable flat sealing at temperatures approaching +300Â°C.
