Introduction
The ASME SA182 F304 Forged Flange is a high-quality stainless steel flange designed for reliable performance in heat exchanger factories and process piping systems. Made from austenitic stainless steel 304, it provides excellent resistance to oxidation, corrosion, and moderate chloride environments.
This flange type is Long Weld Neck Raised Face (LWNRF), designed for high-temperature and high-pressure applications, making it especially suitable for boilers, pressure vessels, and heat exchangers. DLSS supplied the 2″ size, length 310 mm, pressure class 150#, ASME B16.5 compliant for international projects.
