What is a Threaded/Socket Weld Half Coupling?

A Threaded/Socket Weld Half Coupling is a forged pipe fitting used to connect a small-diameter pipe to a larger piping system or vessel. It features only one end designed to connect to the pipeline, with the other end typically welded or left blank. These couplings are ideal for branch connections or instrumentation access in high-pressure piping systems.

  • Threaded Half Coupling: Equipped with internal threads for quick, reliable, and leak-tight connections without welding. Perfect for applications where future disassembly or replacement is expected.

  • Socket Weld Half Coupling: Features a recessed socket for pipe insertion, followed by fillet welding. This ensures a strong, permanent bond—ideal for high-pressure, vibration-prone systems.

These fittings are widely used in fluid and gas handling systems requiring a secure, compact, and durable branch connection.

Material Grades We Use

At Fortis Forge, our Half Couplings are engineered using top-quality materials for strength and reliability:

  • Carbon Steel (ASTM A105)
    → High tensile strength and excellent pressure resistance. Ideal for demanding industrial applications involving elevated pressure or temperature.

  • Mild Steel (IS 2062)
    → Economical and easy to fabricate. Suitable for low-pressure, general-purpose piping systems.

Each product undergoes rigorous quality checks to meet global standards, ensuring:

  • Precise threading (per ANSI/ASME B1.20.1)

  • Uniform socket depth and bore dimensions

  • High tensile and mechanical integrity

  • Long-term resistance to stress, corrosion, and pressure fluctuations
