ASTM A790/ASME SA790 Standard Specification for Seamless and Welded Ferritic/Austenitic Stainless Steel Pipe

Get Updated ASTM A790 UNS S32750 Super Duplex Welded Pipe Price list, Know ASTM A790 Duplex 2205 Square Pipe thickness.

ASME SA/A790 is a specification developed by the American Society of Mechanical Engineers (ASME) that covers the requirements for seamless and welded duplex stainless steel pipes. These pipes are commonly used in various industries, particularly in applications where corrosion resistance and high strength are critical. The "SA" stands for "Specification for Piping Applications," and the "A790" is the specific designation for this standard.

Duplex stainless steels are a group of materials that combine the advantages of both austenitic and ferritic stainless steels. They are known for their excellent corrosion resistance, high mechanical strength, and good weldability. ASME SA/A790 pipes are designed to meet the stringent requirements of various industries, including chemical processing, oil and gas exploration, marine applications, and more.

Material Grades: The specification covers a range of duplex stainless steel grades, including UNS S31803, UNS S32205, UNS S32750, UNS S32760, and others. These grades offer varying levels of corrosion resistance and mechanical properties to suit different applications.

Manufacturing Methods: ASME SA/A790 pipes can be produced using both seamless and welded methods. Seamless pipes are manufactured without any welding, while welded pipes are fabricated by joining two or more sections through welding processes.

Dimensions and Sizes: The specification outlines the dimensional requirements, such as diameter, wall thickness, and length, for ASME SA/A790 pipes. These dimensions are crucial to ensure compatibility with various piping systems.

Testing and Quality Control: The standard includes provisions for rigorous testing and quality control procedures to ensure the pipes meet the specified requirements. This may include hydrostatic testing, non-destructive testing, chemical analysis, and mechanical property testing.

Heat Treatment: The specification may specify heat treatment requirements to improve the mechanical properties and corrosion resistance of the pipes.

Marking and Identification: ASME SA/A790 pipes are typically marked with essential information, such as the material grade, size, heat number, and manufacturer's logo or name, for easy identification and traceability.

ASME SA/A790 is an important standard for duplex stainless steel pipes used in critical industrial applications. These pipes provide a balance between strength and corrosion resistance, making them suitable for a wide range of demanding environments. Compliance with this specification ensures the quality and reliability of these pipes in various industries.
