DN32 HASTELLOY B3 Socket Weld RF Flange – PN16

SSM provides high-quality DN32 Hastelloy B3 flanges with Socket Weld (SO) and Raised Face (RF) design, rated at PN16, ideal for corrosive and high-temperature environments in chemical and industrial applications.

Material Composition – Hastelloy B3

Hastelloy B3 is a nickel-molybdenum alloy designed for resistance to strong oxidizing agents and corrosive media, especially in nitric acid and mixed acid applications. Key chemical composition includes:

Nickel (Ni): 63–69%

Molybdenum (Mo): 15–18%

Iron (Fe): ≤ 5%

Cobalt (Co): ≤ 3%

Carbon (C): ≤ 0.03%

Manganese (Mn), Silicon (Si), Sulfur (S), Phosphorus (P): ≤ 1%

Features

Socket Weld (SO): Provides strong, leak-proof joints suitable for small-diameter piping.

Raised Face (RF): Ensures reliable gasket sealing under high-pressure conditions.

Pressure Rating: PN16, suitable for medium-pressure industrial systems.

Corrosion Resistance: Excellent resistance to oxidizing acids and harsh chemical environments.

Compliance: Manufactured according to ASME B16.5 and international standards.

Applications

Chemical processing plants

Nitric acid and mixed acid pipelines

Pharmaceutical and food processing equipment

Offshore and marine systems

Industrial corrosion-resistant piping
