ASTM A860 A860M Standard Specification

What is ASTM A860 A860M Standard?

ASTM A860 A860M standard is a set of guidelines and specifications for the manufacture and testing of high-strength, low-alloy steel pipe fittings. These pipe fittings are commonly used in the oil and gas industry, as well as other industrial applications where high strength and corrosion resistance are required.
The standard covers a wide variety of fittings, including elbowsteesreducerscaps and crosses. It also includes requirements for materials, testing and quality control. The standard is designed to ensure that fittings meet the highest standards of quality, durability and performance.
A key feature of the ASTM A860 A860M standard is its emphasis on metal materials. The standard specifies that fittings must be made of high-strength, low-alloy steel. Known for its strength and corrosion resistance, this steel is well suited for use in the harsh environments of the oil and gas industry.
The standard also includes testing and quality control requirements. This ensures that fittings meet the necessary performance standards and are free of defects. Testing includes destructive and non-destructive test methods, such as radiographic and ultrasonic testing.
In addition, the standard includes fitting marking and packaging guidelines to ensure proper identification and protection of fittings during shipping and storage.
Overall, the ASTM A860 A860M standard is an important set of guidelines for the manufacture of high-strength, low-alloy steel pipe fittings. It ensures that these fittings meet the highest standards for quality, durability and performance, making them suitable for a wide range of industrial applications.
In short, if you’re looking for high-strength, corrosion-resistant fittings for your oil and gas or industrial applications, ASTM A860 A860M Standard is the best choice. It guarantees that the fittings you receive are of the highest quality and will perform as expected, even in the harshest environments.

ASTM A860 A860M Standard Specification


1.1 This specification covers wrought high-strength lowalloy steel butt-welding fittings of seamless and electric fusion welded.

construction covered by the latest revisions of ASME B16.9, ASME 16.28, and MSS-SP-75. Butt-welding fittings differing from these ASME and MSS standards shall be furnished in accordance with Supplementary Requirement S58 of Specification A 960/A 960M. These fittings are for use in high-pressure gas and oil transmission and distribution systems.

1.2 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.

1.3 This specification does not cover cast-welding fittings or fittings machined from castings.

1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification. Unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished to inch-pound units.
