Metal Union
A Metal Union is a type of pipe fitting designed to join two pipes together while allowing easy disconnection without causing any deformation or damage to the pipes. Unlike couplings, unions are made of three parts—two end pieces and a central nut—that enable simple installation and removal. Manufactured using carbon steel, stainless steel, alloy steel, brass, and duplex steel, metal unions provide a strong, leak-proof, and reusable joint. They are widely used in oil & gas, petrochemical, power plants, chemical processing, water treatment, and HVAC systems, where frequent pipe maintenance, inspection, or replacement is required.
Key Features of Metal Union
- Reusable Joint – Allows easy disconnection and reconnection of pipes.
- Leak-Proof Design – Ensures safe and reliable sealing under pressure.
- Strong & Durable – Made from high-quality metals to handle harsh industrial conditions.
- Corrosion & Heat Resistant – Suitable for high-temperature and corrosive environments.
- Versatile Connection Options – Available in threaded, socket-weld, and butt-weld types.
- Meets International Standards – Manufactured according to ASME, ASTM, DIN, and EN norms.
