Flange A182 refers to forged stainless steel flanges manufactured in accordance with ASTM A182 and ASME SA182 standards. These flanges are widely used in piping systems requiring corrosion resistance, high strength, and durability under elevated temperatures.
Material Properties of Flange A182
Flange A182 is typically produced from chromium-nickel austenitic stainless steel, such as Grade F304. The chemical composition usually includes carbon, manganese, phosphorus, silicon, sulfur, 18% chromium, and 8% nickel. This combination ensures:
- High strength: minimum yield strength of 205 MPa and tensile strength of 515 MPa.
- Excellent heat resistance: melting point around 1400°C and service temperature up to 870°C.
- Corrosion resistance: suitable for aggressive and corrosive industrial environments.
Types of Flange A182
Depending on the design and connection requirements, flange A182 is available in several types:
- Weld Neck (WN)
- Slip On (SORF)
- Blind (BLRF)
- Socket Weld (SW)
- Lap Joint (LJ)
- Ring Type Joint (RTJ)
Face types also vary, including flat face (FF), raised face (RF), and ring type joint (RTJ).
Industrial Applications
Flange A182 is widely applied in industries such as:
- Oil & Gas pipelines
- Power generation
- Boilers and heat exchangers
- Water supply systems
- Petrochemical and general corrosive services
