ASTM B514: Specification
This is the American Society for Testing and Materials (ASTM) standard for welded, cold-worked, and annealed nickel-iron-chromium alloy pipe. This specification ensures that the pipe meets specific quality requirements for chemical composition, mechanical properties, and manufacturing process.
Welding: A manufacturing process
This involves forming the pipe from flat rolled alloy (sheet or strip) and then welding it.
Automatic Welding: Pipes are manufactured using an automated welding process without the addition of filler metal.
Cold Working: After welding, the pipe material is cold worked to improve its mechanical properties.
Pickling: Surface Treatment
Pickling is a chemical surface treatment used to remove scale and impurities from metal surfaces.
Corrosion Protection: Cleans and passivates the surface, improving its corrosion resistance.
Pretreatment: This treatment is essential for applications requiring a clean, scale-free surface.
Typical Applications
This pipe's properties make it an ideal choice for extreme operating environments across a variety of industries:
Petrochemical and Chemical Processing: Used in heat exchangers, furnace components, and piping handling high-temperature, corrosive materials.
Power Generation: Used in high-temperature components such as steam superheaters in power plants, including nuclear power plants.
Heat Treatment Equipment: Used in muffle furnaces, retorts, and radiant tubes in industrial furnaces.
