What is AStm A860?

ASTM A860 is the standard specification for wrought high-strength ferritic steel butt-welding fittings of seamless and electric fusion-welded construction. These pipe fittings shall be furnished in accordance with the dimensions of ASME B16. 9(for sizes NPS 14 and smaller) or MSS SP 75(for sizes NPS 16 through NPS 48).

What is WPHY?

WPHY stands for Wrought High Yield Strength as its feature and grade itself suggest about its high yield strength. These fittings are generally used at High-Pressure requirements. This specification covers wrought high-strength low-alloy WPHY 65 fittings of seamless and electric fusion-welded construction.

What WPHY 52?

Our ASTM A860 WPHY 52 Pipe Elbows, where the WPHY stands for Wrought Pipe High-Yield, are high in tensile strength, are impervious to general corrosion and aid the fertilizer production units. Our 100% durable products are capable of undergoing customer specific customization.

What is MSS standard?

The Manufacturers Standardization Society of the Valve and Fittings Industry (MSS) publishes international codes and standards to ensure interoperability, compliance and operation of process piping systems.

What material is ASTM A694 F60?

ASTM A694 F60 Standard Specification for Carbon and Alloy Steel Forgings for Pipe Flanges, Fittings, Valves, and Parts for High-Pressure Transmission Service. Several grades of material, based on minimum yield strength requirements, are covered Materials adhere to testing and tensile property requirements as well.

What is basic function of MSS?

The primary function of MSS is to provide its members the means to develop engineering standard practices for the use and benefit of the industry and users of its products.

What is MSS code?

The Manufacturers Standardization Society (MSS) of the Valve and Fittings Industry is a non-profit technical association organized for development and improvement of industry, national and international codes and standards for: Valves, Valve Actuators, Valve Modification, Pipe Fittings, Pipe Hangers, Pipe Supports.

What is the ASTM a860 standard for wrought steel?

Active Standard ASTM A860 / A860M | Developed by Subcommittee: A01.22 This 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.

What makes ASTM a860 butt welding pipe fittings so good?

The high-strength pipe fittings of ASTM A860 shall be made from fully killed fine-grain material made by a melting process that is intended to produce rounded, well dispersed, fine sulphide inclusions, that promote good notch toughness, assists in the resistance to hydrogen induced cracking, and for weldability suitable for field welding.

How are ASTM a860 WPHY 42, 52, 60, 70 fittings treated?

ASTM A860 WPHY42, 46, 52, 56, 60, 65 and 70 all fittings shall be heat treated. Fittings that formed above transformed temperature or made by weldings, shall be cooled down to critical temperature before heat treatment. The methods including normalizing, quenching, tempering or stress relieved under the specification of ASTM A960/960M.
