Technical Lecture: The Impact of Wet Process Phosphoric Acid Cargo (Wet-PAC) on Stainless Steel Corrosion in Gdynia, Poland.

ISTECH Metal Finish provides customized lectures for its clients and interested parties. The lecture topics include:

1. Chemical and mechanical methods for cleaning/treating corroded stainless steel cargo tanks on chemical tankers.
2. A detailed discussion on severe corrosion damage in stainless steel cargo tanks on chemical tankers, including the effects of wet phosphoric acid cargoes.We explain how chemical tanker operators can protect their interests in the face of damage to stainless-steel tanks from the carriage of wet process phosphoric acid.
3. The correct sequence and techniques for processing stainless steel, such as grinding, polishing, welding, pickling, and passivation.
4. An overview of quality testing equipment, including passivity testers, roughness measurements, pit corrosion depth gauges, and tests for foreign iron contamination.
5. Solutions for repairing corrosion damage through mechanical and/or chemical surface treatments.
6. Strategies to minimize corrosion damage to stainless steel.
7. The significance of maintaining stainless steel.
8. Maintenance procedures for Stainless Steel Marine (Exhaust Gas Cleaning Systems) Scrubber Towers.

In March 2024, ISTECH was approached by Stodig Ship Management and Seatrans Norway to conduct a lecture, lasting approximately two hours, on the subject of corrosion damage in stainless steel cargo tanks. The focus was particularly on the potential effects of Wet Process phosphoric acid being loaded into these tanks, along with strategies for corrosion prevention and various mechanical and chemical treatments to address existing corrosion. The session was conducted in partnership with Brookes Bell from Liverpool, a premier multi-disciplinary technical and scientific consultancy serving the maritime and energy sectors. The afternoon proved to be fruitful, covering all facets of corrosion damage, its monitoring, solutions, and preventative measures. The attendees, all professionals from the maritime industry with varying degrees of involvement in the topic, engaged with insightful questions and expressed high satisfaction with the lecture format.
