At M Metal Tubes India Pvt Ltd, we manufacture high-quality Piece Unions that are engineered for easy assembly, disassembly, and maintenance in piping systems. Our unions deliver strong, reusable, and leak-proof connections—ideal for demanding industrial applications such as oil & gas, petrochemical, power generation, and water treatment systems.

What is a Piece Union?

A Piece Union is a versatile pipe fitting that allows two pipes to be connected securely while still being detachable without cutting or welding. Unlike couplings, unions are designed for repeated use, making them perfect for pipelines and systems that require regular maintenance, inspection, or modification.

Types of Piece Unions We Offer

1. Socket Weld Union

Our Socket Weld Unions are built for high-pressure applications, providing a robust, leak-proof seal through socket welding. They ensure reliable, vibration-resistant connections in critical systems.

2. Threaded Union

The Threaded Union features precision-cut internal threads, allowing for quick and easy assembly without the need for welding—ideal for low to medium-pressure applications or systems that require frequent dismantling.

3. Butt Weld Union

Butt Weld Unions offer a permanent, seamless, and high-strength connection, ensuring structural integrity and long-lasting performance in high-pressure or corrosive environments.
