Passivation
ChunwooTech’s metal surface treatment technology is a technology that forms a coat (passivation) on the surface using chemicals that do not contain toxic substances on steel pipes (stainless steel and duplex) used in plants, construction, and shipbuilding.
Cargo Spool Passivation/Pump Tower
We use our patented CW-R2 and CW-R2G technologies to form passivation coats on cargo spools, which are not suitable for the traditional dipping method due to the complicated structure and the attachment of valves and other instruments during production.
