BS 3076 NA13 ASTM A164 Nickel alloy pipe 12'' Seamless Steel Pipe 6-12m
Specifications
Nickel Alloy Pipe
Alloy 400 possesses excellent corrosion resistance to many reducing media. It can be used in contact with fluorine, hydrofluoric acid, hydrogen fluoride or their derivatives – its resistance to hydrofluoric acid has been demonstrated in all concentrations up to the boiling point. It is also resistant to many forms of sulfuric and hydrochloric acids under reducing conditions and it also performs well in seawater. Alloy 400 is resistant to stress corrosion cracking and pitting in most fresh and industrial waters. It is therefore widely used in marine engineering, chemical and hydrocarbon processing equipment, valves, pumps, shafts, fittings, fasteners, and heat exchangers.
