ASME B16.11 Boss Manufacturers and Suppliers:
A Forged Boss is a type of fitting used in piping systems, typically to connect two pipes of different sizes or to change the direction of flow. It is made by forging, a manufacturing process where the metal is heated and shaped using compressive force.
The B16.11 standard is a specification for forged fittings, including Bosses, used in high-pressure piping systems. It provides guidelines for the design, dimensions, materials, and testing of these fittings.

ADCO Forge and Fittings is a Manufacturer and Supplier of high-quality Forged Bosses, as well as other types of forged fittings, such as elbows, tees, and couplings. With years of experience in the industry, reputation for producing reliable, durable, and precision-engineered fittings that meet or exceed industry standards. products are used in a wide range of applications, including oil and gas, petrochemical, power generation, and water treatment. We committed to providing exceptional customer service, timely delivery, and competitive pricing to its customers worldwide.
The B16.11 Boss dimensions specify the size, shape, and tolerance of the threaded or socket weld ends, as well as the diameter and length of the boss itself. The dimensions vary depending on the nominal pipe size and pressure rating of the fitting.
A Screwed or Threaded Boss is a type of Forged Boss with threaded ends, which can be screwed onto pipes or other fittings with compatible threads. This type of boss is commonly used in low-pressure applications.
A Socket Weld Boss is a type of Forged Boss with socket weld ends, which can be welded directly to pipes or other fittings with compatible socket weld ends. This type of boss is commonly used in high-pressure applications.
We have the ready inventory of Forged Boss in the different size ranges of 7/8 Npt, 12 mm, 9 mm, 10 mm, 1/2 Npt, 1/4 Npt, 5/8 Npt, 7/16 Npt, 7/8 Npt, 2 Inch, 1 Inch, 3 Inch, 4 Emt, 5 Inch, 6 Inch, 7 Inch, 8 Inch Socket Weld and Threaded Boss.
