BOZHONG products can be supplied in wide range of dimensions starting from 5 mm thickness up to very high unit weights.
Application
Cryogenic storage and transport of liquefied gases demand the highest level of safety, a criteria that is fully satisfied by the steels used in these applications.
LNG – Storage & transport
• 9%Ni for LNG storage tanks up to 200.000m3 capacity
• 9%Ni steel for 304L steel pipes for LNG transport (jetty to tank)
• 9%Ni hulls for GBS, FLNG structures
