Eccentric Reducer As Per ASTM A860
- ASTM A860 Standard Specification for Wrought High-Strength Ferritic Steel Butt-Welding Fittings
ASTM A860 Standard Specification covers wrought high-strength low-alloy butt-welding steel fittings of seamless and electric fusion-welded construction for applications in high-pressure gas and oil transmission and distribution systems.
Scope
This specification covers wrought high-strength ferritic steel butt-welding fittings of seamless and electric fusion-welded construction. Dimensions of the fittings are provided in the latest revisions of ASME B16.9 and MSS-SP-75. Butt-welding fittings differing from ASME B16.9 shall be furnished in accordance with Supplementary Requirement S58 of Specification A960/A960M. These fittings are for use in high-pressure gas and oil transmission and distribution systems.
Optional supplementary requirements are provided for fittings when a greater degree of examination is desired. One or more of the supplementary requirements may be specified in the order.
This specification does not cover cast-welding fittings or fittings machined from castings.
The ASTM A860 WPHY 60 eccentric reducer is a high-yield material fitting used between two different diameter pipes to keep them on the same level but with an offset centerline. ASTM A860 WPHY 60 eccentric reducer must meet both the chemical composition and mechanical property parameters. It is cost-effective and can be used in high-pressure gas and oil transportation systems in the oil and gas industry due to its high strength and superior corrosion resistance.
