Pipe Union is a mechanical fitting designed to connect two pipes while allowing easy disconnection and reconnection without cutting or damaging the piping. Unlike traditional welded or flanged joints, unions provide a convenient and leak-proof method for maintenance, inspection, or replacement of pipelines—especially in confined or modular systems.
Pipe unions consist of three parts: a male end, a female end, and a central nut that pulls the two ends together to form a tight seal. The sealing may be achieved via metal-to-metal contact or with the use of elastomeric seals, depending on pressure and temperature requirements.
Unions are commonly used in water supply systems, petrochemical plants, compressed air lines, fire protection systems, and industrial utility pipelines, especially where frequent dismantling or reassembly is required. Their design ensures minimal disturbance to the system during maintenance, making them a popular choice in both temporary and permanent installations. for pipes click here
