ASME B16.11 Union Manufacturers and Suppliers:
A forged steel union is a type of pipe fitting used to connect two pipes or sections of piping together. It is made by forging steel to create a strong, durable, and leak-proof joint.
Orifice union fittings are a specific type of forged steel union that are designed to allow precise measurement and control of fluid flow. feature a small hole or “orifice” in the center of the fitting that restricts the flow of fluid, allowing for accurate measurements to be taken.

ADCO Forge and Fittings is a well-known Manufacturer of high-quality forged steel unions and fittings. With years of experience in the industry, specialize in producing a wide range of products, including orifice union fittings, screwed/threaded unions, socket weld unions, and galvanized unions. We are committed to using the latest technology and state-of-the-art equipment to ensure that our products meet the highest standards of quality and durability. Our dedication to customer satisfaction and exceptional service has earned them a reputation as a trusted and reliable supplier in the industry.
Screwed or threaded unions are a type of forged steel union that feature threads on the inside of the fitting that allow it to be screwed onto a threaded pipe or fitting. Forged unions are commonly used in low-pressure applications.
Socket weld unions are another type of forged steel union that feature a socket on one end of the fitting that allows it to be welded onto a pipe or fitting. Socket weld unions are typically used in high-pressure applications.
Galvanized unions are forged steel unions that have been coated with a layer of zinc to protect against corrosion. Galvanized unions are commonly used in outdoor or corrosive environments.
We have the ready inventory of Forged Union in the different size ranges of 3/4 Npt, 1 1/2 Emt, 1/2 Npt, 5/8 Npt, 3/4 Npt, 1/2 inch, 2 Inch, 1 Inch, 3 Inch, 4 Inch, 5 Inch, 6 Inch, 8 Inch Socket Weld and Threaded Union.
