Metal Threaded Union
A Metal Threaded Union is a pipe fitting designed to connect two threaded pipes while allowing quick disassembly and reassembly without cutting or damaging the pipe. It consists of three parts: a male end, a female end, and a central nut that secures the joint. Threaded unions are commonly used in small-diameter pipelines where maintenance, replacement, or frequent disconnection is required. Manufactured from carbon steel, stainless steel, alloy steel, brass, and duplex steel, these unions provide strong, leak-proof, and reusable joints, making them suitable for oil & gas, chemical processing, plumbing, HVAC, and water supply applications.
Key Features of Metal Threaded Union
- Threaded Connection – Enables easy assembly and disassembly without welding.
- Reusable & Cost-Effective – Designed for repeated use without loss of performance.
- Leak-Proof Design – Provides a tight seal under high-pressure applications.
- Durability – Manufactured from robust metals to withstand industrial conditions.
- Corrosion & Heat Resistance – Suitable for harsh and corrosive environments.
- Standard Compliant – Meets ASME, ASTM, DIN, and EN specifications.
