About ISTECH

ISTECH provides technical inspections, upgrading and repair – treatments of stainless steel cargo tanks, piping systems, installations and scrubbers (new and in service) worldwide by means of mechanical polishing, (pit) corrosion removal, pickling and passivation for material types such as SUS 304, 316 (L) (LN) , 254SMO , duplex 2205 and all other SS material types. ISTECH Metal Finish BV is a professional company, with extensive knowledge and understanding of stainless steel passivation, since 30 years our customers (mainly ship owners) are fully satisfied with the results.

Quality objectives of stainless steel surface inspection, performance, quality control, supervision & troubleshooting:

A clean and passive surface finish is crucial to corrosion resistance. Stainless steel is protected from corrosion by its passive layer - a thin, impervious, invisible, surface layer that is primarily chromium oxide. The oxygen content of the atmosphere or of aerated aqueous solutions is normally sufficient to create and maintain ('self-heal') this passive layer. Unfortunately, surface defects and imperfections introduced during manufacturing or caused by aggressive chemical loadings may drastically disturb this 'self-healing' process and reduce resistance to several types of local corrosion.

Thus, as regards hygiene and corrosion, a final cleaning process is required to restore an acceptable surface quality.

  • Pickling and passivation of cargo tanks - heating coils - piping systems
  • Power buffing (grinding and polishing of cargo tanks (smooth surfaces)
  • Ferroxyl testing (evidence for (non) presence of ferrous contamination)
  • Oxilyser passivity testing (evidence of (non) passive oxide layer)
  • Surface roughness testing (evidence of (in) correct surface finish with
  • regards to roughness)
  • Inspection / quality control / supervision / troubleshooting
