从India供应商批量进口A182 F91 Alloy Steel Globe Valve

The A182 F91 Alloy Steel Globe Valve is a pressure-rated control valve built for throttling and shutoff in high-temperature, high-pressure systems. It uses ASTM A182 F91 chrome-moly alloy steel, a 9Cr-1Mo-V modified ferritic steel known for creep resistance at elevated temperatures. The globe design provides precise flow regulation with a disc that moves perpendicular to the seat, minimising erosion in high-velocity streams.

This valve is supplied with a bolted bonnet and rising stem for clear visual position indication. The alloy composition typically includes 8.5 - 9.5 % chromium, 0.85 - 1.05 % molybdenum, and 0.18 - 0.25 % vanadium, delivering tensile strength around 600 MPa at room temperature. Industry practice for F91 valves includes NACE MR0175 compliance for sour service and ASME B16.34 pressure-temperature ratings. Common end connections are RF or RTJ flanges to ASME B16.5.

Primary buyers are EPC contractors and end-users in power generation, petrochemical refining, and combined-cycle plants. These sectors specify F91 for superheated steam lines up to 600 °C and pressures exceeding 2500 PSI. Sourcing from India benefits from established foundries and forging capacity for alloy grades, with typical lead times for custom sizes running 12 - 16 weeks. Confirm MOQ, flange rating, and NDE requirements with the supplier before ordering.
