Passivation of Stainless steel

It's well known that the SUS materials (piping) very often demand a final step of surface treatment, i.e. passivation, in order to achieve a product with acceptable visual appearance and high corrosion resistance. The passivation process removes chips and “free iron” contaminations left behind on the surface from different fabrication operations. These contaminants are potential … Continue reading Passivation of Stainless steel

PSPC – Performance Standard for Coating of Ballast Tanks – Part 2

Continue on Part 1  We will talk about the concept of Structure inspector during surveying with the mean of Painting quality protection. PSPC requirement for the steel works as below: The steel surface shall be prepared so that the coating achieves an even distribution at the specified nominal dry film thickness of 320 micron and … Continue reading PSPC – Performance Standard for Coating of Ballast Tanks – Part 2

PSPC – Performance Standard for Coating of Ballast Tanks – Part 1

History briefs: In 2002, TSCF published “Guidelines for Ballast Tank Coating Systems and Surface Preparation” provided differing levels of standards for minimum target coating life of 10, 15 and 25 years (denoted as TSCF10, TSCF15 and TSCF25). In order to address the same issue for all vessels, in 2006 IMO adopted Resolution MSC 215(82) “ … Continue reading PSPC – Performance Standard for Coating of Ballast Tanks – Part 1
