Alloy steel flanges are forged components from chrome-molybdenum alloys like F11, F22, or F91 (ASTM A182), engineered for high-temperature/pressure bolting in power plants and refineries. They resist creep/oxidation up to 1200°F, available as weld neck, slip-on, socket weld, blind, or RTJ types matching prior CS/mild steel variants and SS fittings.​

Types
  • Weld Neck: Tapered hub minimizes stress in cyclic service.

  • Slip-On/Socket: Economical double-weld for smaller bores.​

Specifications

Classes 150#-2500# per ASME B16.5; F22 (2.25Cr-1Mo) tensile ≥515 MPa, sizes 1/2"-60" NPS.

Alloy Steel F22 socket weld flanges are forged components from ASTM A182 Grade F22 (2.25Cr-1Mo) designed for high-temperature, high-pressure small-bore piping, featuring a socket for pipe insertion and fillet welding before bolting. Slip-on variants slide over pipe ends (double-welded inside/outside) for cost-effective connections in refineries and power plants, complementing prior F22 WNRTJ/socket weld flanges, SS fittings, and reducers.​

Key Features

F91 grade offers superior creep strength to 1200°F with 9Cr-1Mo-V composition; classes 3000#-9000# per ASME B16.11, sizes 1/2"-4" NPS match socket weld patterns but with slip-on bore slightly larger than ID.​

Specifications

Tolerances ensure weld alignment; used where full penetration isn't critical vs weld neck types.

Stainless steel flanges are forged or cast components used to connect pipes, valves, and pumps in industrial piping systems, offering superior corrosion resistance in harsh environments. They adhere to standards like ASME B16.5, ASTM A182, and ANSI, with common grades including 304, 316, and 316L for applications in chemicals, oil & gas, and pharmaceuticals.​

Main Types
  • Weld Neck Flange: Tapered hub provides strength and stress reduction for high-pressure lines.​

  • Slip-On Flange: Slides over pipe ends and welds inside/outside, cost-effective for moderate pressures.​

  • Blind Flange: Seals pipe ends, used for testing or isolation.​

  • Socket Weld & Threaded: For smaller, high-pressure pipes with welding or threading.​

Key Specifications

Flanges range from Class 150 to 2500, sizes 1/2" to 60", with raised face (RF), flat face (FF), or ring type joint (RTJ) faces for gasketing. SS 304/316 ensures durability up to 1000°F.​
