Is the Screw with 2 x BSP female thread, cast iron, type 340/54 suitable for temperatures up to +300Â°C and pressures of 20â25 bar?

Yes. The Screw with 2 x BSP female thread, cast iron, type 340/54 is suitable for temperatures up to +300Â°C and pressures of 20â25 bar, with the following conditions: it is rated for operating temperatures up to +300Â°C; working pressure is specified as 25 bar up to +120Â°C and 20 bar up to +300Â°C. Therefore at +300Â°C the allowable working pressure is 20 bar; pressures up to 25 bar are acceptable only if the temperature does not exceed +120Â°C.

Can the Screw with 2 x BSP female thread, cast iron, type 340/54 maintain a reliable conical seal at 300Â°C and 20 bar?

Yes. The Screw with 2 x BSP female thread, cast iron, type 340/54 is designed for conical sealing between internal components and rated for operation up to +300Â°C with a working pressure of 20 bar at that temperature. Therefore, when installed correctly and used within specified limits (material ductile iron, correct BSP connections, proper assembly/tightening and compatible mating parts), it can maintain a reliable conical seal at 300Â°C and 20 bar.

Does the Screw with 2 x BSP female thread, cast iron, type 340/54 require special gaskets for 300Â°C and 20â25 bar?

Screw with 2 x BSP female thread, cast iron, type 340/54 does not require additional flat gaskets for its primary sealing function because it relies on conical sealing between internal components (threaded/conical seat) for pressure-tight joints. However, at the specified extreme conditionsâup to +300Â°C and working pressure 20â25 barâconsiderations are: - The built-in conical sealing is rated for operating temperature up to +300Â°C and working pressure 25 bar (up to +120Â°C) and 20 bar (up to +300Â°C), so it is designed for these conditions without special external gaskets. - If any joint faces, flange mates, or auxiliary connections are present (e.g., mating surfaces not part of the conical seat) or if assembly damage/corrosion prevents reliable metal-to-metal sealing, use of high-temperature gaskets or soft-seal inserts appropriate for 300Â°C (e.g., graphite, mica, or other certified high-temperature materials) may be advisable. - For steam, aggressive media, or cyclic thermal/pressure loading, selecting compatible gasket materials and verifying chemical compatibility and creep/relaxation at 300Â°C is recommended. - Follow manufacturerâs assembly torque/specifications; improper assembly can compromise the conical seal and necessitate supplemental sealing. - For safety and compliance, verify with the product datasheet or manufacturer whether any specific gasket type or installation practice is mandated for operation at 300Â°C and 20â25 bar. Summary: Screw with 2 x BSP female thread, cast iron, type 340/54 is designed to seal by conical internal seating for temperatures up to 300Â°C and pressures up to 20â25 bar, so special gaskets are not generally requiredâexcept where mating conditions, media, or service conditions warrant high-temperature gasket materials or manufacturer-recommended seals.
