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.
