Comprehensive Stock of ASME B16.11 Forged Unions – Threaded & Socket Weld End Connections – Supplied in ASTM A105 Carbon Steel, A182 F304L/F316L Stainless Steel, Alloy Steel F11/F22, Duplex and High-Performance Nickel-Based Alloys like Inconel 625, Monel 400 & Hastelloy C276. Union fittings play a vital role in piping systems by providing a simple and reusable method for connecting two pipes or tubes. Unlike permanent welded or threaded joints, unions allow easy disassembly without causing damage to the piping, making them ideal for maintenance, repair, or replacement tasks. Typically composed of three parts — a nut, a female end, and a male end — unions create a secure, leak-tight seal when assembled correctly. There are various types of unions designed to suit different applications, primarily socket weld unions and threaded unions. Socket weld unions are welded directly to pipe ends, ensuring a strong, permanent connection, while threaded unions use screw threads, allowing quick and convenient pipe disconnection. These fittings are available in sizes from 1/8” to 4” and pressure ratings such as Class 2000, 3000, 6000, and 9000, accommodating a wide range of industrial needs. Manufactured according to stringent international standards like ASME B16.11 and MSS-SP-83, forged unions offer excellent strength, durability, and resistance to leaks. They are produced using a variety of materials, including Carbon Steel (ASTM A105, A350 LF2), Stainless Steel (ASTM A182 F304, F316, F321), Alloy Steel (F11, F22, F91), Duplex and Super Duplex Steel, and Nickel Alloys such as Inconel, Monel, and Hastelloy. Precision forging, heat treatment, and machining processes ensure that these unions meet high mechanical and dimensional standards, suitable for demanding pressure and corrosive environments. Unions are widely used in sectors such as oil and gas, petrochemical, power generation, chemical processing, and marine engineering. Their ability to provide quick, reliable disconnection and reconnection makes…
