Overview

Product overview

Forged Union fittings are a type of Forged Fittings, crucial in piping systems, enabling the connection of two pipes or sections of piping with a strong, durable, and leak-proof joint. At Fortune Fittings Private Limited, we specialize in manufacturing high-quality ASME B16.11 Unions, both threaded and socket weld types, suitable for various industrial applications.

What is a Forged Union?

ASME B16.11 unions are standardized by the American Society of Mechanical Engineers (ASME), ensuring consistent dimensions and specifications. These unions are forged, a process involving heating and shaping steel to create robust fittings that can withstand high pressures and provide reliable performance.

Types of Forged Steel Unions

  • Threaded (Screwed) Unions:Description: These unions have internal threads, allowing them to be screwed onto pipes or fittings with matching threads.
  • Applications: Commonly used in low-pressure applications where ease of assembly and disassembly is needed.
  • Socket Weld Unions:Description: These unions feature a socket on one end, enabling them to be welded onto pipes or fittings with compatible socket weld ends.
  • Applications: Ideal for high-pressure applications requiring a permanent, strong joint.
  • Galvanized Unions:Description: These unions are coated with a layer of zinc to prevent corrosion, making them suitable for outdoor or corrosive environments.
  • Applications: Widely used in environments exposed to moisture or chemicals to prevent rust and corrosion.
  • Orifice Unions:Description: These specialized unions have a small hole or “orifice” in the center, allowing for precise measurement and control of fluid flow.
  • Applications: Used in systems where accurate flow measurement and control are critical, such as in chemical processing or fluid handling.

Conclusion

Our commitment to quality, wide range of material options, and adherence to international standards ensure that our forged unions meet the most demanding industrial requirements. Contact us today to learn more about our products and how we can fulfill your piping system needs.
