ASME SB514 Incoloy 800H Weld Tube nickel-iron-chromium alloys steel for general corrosive service

ASME SB514 is a specification published by the American Society of Mechanical Engineers (ASME) that covers the requirements for seamless and welded tubes made of Incoloy 800H alloy. Incoloy 800H is a nickel-iron-chromium alloy with high strength and excellent resistance to oxidation, carburization, and nitridation. It is commonly used in high-temperature applications such as heat exchangers, furnace components, and petrochemical processing equipment.

The ASME SB514 specification provides guidelines for the dimensions, mechanical properties, and testing requirements of Incoloy 800H weld tubes. It specifies the allowable tolerances for outside diameter, wall thickness, and length of the tubes. The mechanical properties, such as tensile strength, yield strength, and elongation, are also specified to ensure the quality and performance of the tubes.

Furthermore, the ASME SB514 specification outlines the various non-destructive testing methods, such as ultrasonic examination and eddy current examination, that should be conducted to detect any defects or imperfections in the welds. It also includes requirements for the heat treatment of the tubes to achieve the desired mechanical properties.

ASME SB514 provides the necessary guidelines and requirements for the manufacturing and testing of Incoloy 800H weld tubes, ensuring their suitability for high-temperature applications.
