Manufacturer of ASME B16.11 Socket Weld and Threaded Pipe Union in 304 Stainless Steel, class 3000# in India
A union is a fitting used in a system to connects two pipes. However, the union fitting differs from a coupling fitting. This is because the ASME B16.11 Union permits the user with the option of future disconnection of the pipes, simply for maintenance. In contrast to a coupling fitting which necessitates the need for processes such as soldering, solvent welding, or even rotation, which is apt for threaded couplings; a 2 Inch Threaded Brass Union supports easy connection and disconnection. This is an action that could be practised multiple times if needed. Essentially, a Stainless Steel Threaded Union consists of three parts: first is the nut, next - a female end and lastly a male end. When the female and male ends are secured, the nut of this union seals the joint, by clasping both the ends together in a snug manner. These fittings are a kind of very compact flange connector. The ASME B16.11 is a standard which takes into consideration 300# Threaded Union Dimensions, size, the material used, pressure ratings, tolerances, marking, testing etc. Generally, the material used for the production of a Socket Weld Union Fitting includes stainless steel, copper, bronze, brass, alloy steel, carbon steel, Inconel and Hastelloy. The Reducing Socket Weld Union is considered to be a leakproof fitting and is especially important for applications that have the need for a leakproof connection.
