Do You Understand ASTM A860 Standard?

ASTM A860 standard specifies the requirements for wrought high strength ferritic steel butt-welding pipe fittings (critical components used in high-pressure pipeline systems). ASTM A860 covers wrought high strength butt-welding fittings of seamless and electric fusion welded construction, making it a versatile choice for projects that require high strength, excellent weldability, and high-pressure resistance. It is widely used in oil and gas transmission and industrial pipeline systems.

The scope of ASTM A860 covers a range of common butt-welding fittings, designed to connect of pipe in high-pressure systems.

These pipe fittings include:

a. Elbows (45deg and 90deg, long radius and short radius)

b. Tees (equal and reducing tees)

c. Reducers (concentric and eccentric reducers)

d. Caps

Dimensional standard for ASTM A860 pipe fittings

ASTM A860 pipe fittings references two key dimensional standards to ensure compatibility with pipeline systems:

a. NPS 1/2 to NPS 14: Complies with ASME B16.9 (Factory-made wrought butt-welding fittings)

b. NPS 16 to NPS 48: Complies with MSS SP-75 (High-strength, wrought, Butt-welding fittings)

ASTM A860 includes six high strength grades, known as WPHY series, which are matched to API 5L X42 to X70 pipeline pipe grades. Therefore the fittings and pipe share similar mechanical properties.

These WPHY grades are WPHY 42, WPHY 46, WPHY 52, WPHY 60, WPHY 65, WPHY 70.

We can provide multiple types of ASTM A860 high strength pipe fittings, such as elbows, tees, and reducers. They are made of API 5L high strength seamless pipeline pipe. Non-standard pipe fittings can also be made as per clients' drawings. If you are looking for high strength pipe fittings, welcome to visit our website for more details.
