Product Details
Carbon Steel Flanges
Material Grades:
- ASTM A105 (Forged carbon steel for high-temperature service)
- ASTM A350 LF1/LF2/LF3 (Low-temperature carbon steel)
- ASTM A694 F42-F80 (High-yield carbon steel for pipeline applications)
Size Range:
- Diameter: ½" to 60" (or larger for custom orders)
- Pressure Ratings: Class 150 to Class 2500 (ASME B16.5), PN 2.5 to PN 400 (EN 1092-1)
Key Standards:
- ASME B16.5 (Pipe flanges up to 24" NPS)
- ASME B16.47 (Large-diameter flanges, Series A & B)
- EN 1092-1 (European standard for PN-rated flanges)
- MSS SP-44 (Steel pipeline flanges)
Applications:
- Oil & gas pipelines
- Petrochemical plants
- Power generation (non-corrosive environments)
Stainless Steel Flanges
Material Grades:
- Austenitic: ASTM A182 F304/304L, F316/316L, F321
- Duplex/Super Duplex: ASTM A182 F51 (2205), F53 (2507)
- Martensitic: ASTM A182 F6a (410)
Size Range:
- Diameter: ½" to 48" (standard), larger sizes available
- Pressure Ratings: Class 150 to Class 2500 (ASME B16.5), PN 6 to PN 100 (EN 1092-1)
Key Standards:

- EN 1092-1 (European PN/DIN flanges)
- API 6A (Wellhead and Christmas tree flanges for oilfields)
Applications:
- Chemical processing
- Food & pharmaceutical industries
- Marine and corrosive environments
Alloy Steel Flanges
Material Grades:
- Chromium-Molybdenum (Cr-Mo): ASTM A182 F11, F22, F91 (high-temperature service)
- Nickel Alloys: ASTM B564 (Inconel 625, Monel 400, Hastelloy C276)
- Low-Temp Alloys: ASTM A522 (for cryogenic applications)
Size Range:
- Diameter: ½" to 48" (standard)
- Pressure Ratings: Class 150 to Class 2500
Key Standards:
- ASME B16.5 / B16.47
- ASTM A182 (Forged alloy flanges)
- NACE MR0175 (For sour service in oil & gas)
Applications:
- High-temperature/pressure steam systems (power plants)
- Refineries and sour gas pipelines
- Cryogenic storage (LNG)
Manufacturing Processes:
- Forging (ASTM A105, A182) - High strength, preferred for critical applications.
- Casting (ASTM A216 WCB) - Economical for large sizes but less robust than forged flanges.
- Plate Cutting (ASME B16.48 for spectacle blinds) - Used for slip-on and blind flanges.
Common Flange Types:
- Weld Neck (WN) - High integrity for high-pressure systems.
- Slip-On (SO) - Easy alignment, lower cost.
- Blind (BL) - Used to seal pipe ends.
- Socket Weld (SW) - For small-diameter, high-pressure piping.
- Lap Joint (LJ) - Used with stub ends for easy disassembly.
