ASTM B668/ UNS N08028 Nickel Alloy Casing Pipe with VAM TOP Connection
Equal grades of ASTM B668 UNS N08028: alloy 28, 1.4563, Sanicro 28
General introduction of ASTM B668/ UNS N08028/alloy 28/1.4563/ Sanicro 28Nickel Alloy Casing Pipe:
Alloy 28 (UNS N08028, W. Nr. 1.4563) is a nickel-iron-chromium alloy with additions of molybdenum and copper
It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localize attack such as pitting and crevice corrosion
The alloy are especially resistant to sulfuric and phosphoric acid
Used for chemical processing, pollution control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production and pickling equipment
Advantages of ASTM B668/ UNS N08028 /alloy 28/1.4563/Sanicro 28 Nickel Alloy Casing Pipe:
Very high corrosion resistance in strong acids
Very good resistance to stress corrosion cracking (SCC) and intergranular corrosion in various environments
High resistance to pitting and crevice corrosion
Good weldability
Applications of ASTM B668/ UNS N08028 /alloy 28/1.4563/Sanicro 28Nickel Alloy Casing Pipe:
Chemical and petrochemical processing industry
Downhole service in deep sour gas wells
