Is the Cast Iron Screw BSP Female Thread / BSPT Male Thread Type 341/60 suitable for continuous use at temperatures up to +300°C and pressures up to 25 bar?

Cast Iron Screw BSP Female Thread / BSPT Male Thread Type 341/60 is rated for operating temperatures up to +300°C. It is suitable for continuous use at pressures up to 25 bar only when the temperature does not exceed +120°C. At temperatures above +120°C and up to +300°C the maximum allowable working pressure is reduced to 20 bar. Therefore it is not suitable for continuous use at 25 bar across the full +300°C range; use at 25 bar is limited to ≤+120°C.

Can the Cast Iron Screw BSP Female Thread / BSPT Male Thread Type 341/60 maintain sealing integrity and mechanical strength during thermal cycling between ambient and +300°C?

Yes. Cast Iron Screw BSP Female Thread / BSPT Male Thread Type 341/60 is designed to maintain both sealing integrity and mechanical strength during thermal cycling between ambient and +300°C, within its specified limits. Manufactured from high-quality ductile iron and featuring a conical internal sealing surface, the fitting provides a tight, leak-resistant joint that resists mechanical stress. The product is engineered for operation up to +300°C with rated working pressures of 25 bar up to +120°C and 20 bar up to +300°C, indicating the material, thread geometry and sealing design are intended to tolerate repeated temperature excursions in that range. Important caveats: long-term performance during frequent or rapid thermal shocks depends on system-specific factors (cycle rate, temperature gradients, bolt/preload condition, mating material compatibility, use of appropriate sealing compounds or gaskets, and installation torque). For critical or safety‑critical applications, validate with application-specific testing or consult the manufacturer for qualification under the exact cycling profile.
