The pickling process re-forms a passive film, improves corrosion resistance, and further increases quality value.
Welding burn, unevenness due to hand washing and acid cleaning, and oil stains from the manufacturing process are removed by our corrosion treatment through acid cleaning. Reuse of stainless steel - removal of impurities from previously used products.
Improved corrosion resistance through processing!!
This refers to a process for removing welding discoloration from stainless steel and achieving a gray or matte surface. The treatment also slightly improves corrosion resistance.
In iron pickling, it is possible to enhance rust resistance and paint adhesion by simultaneously forming a ferrous phosphate film on the surface during the pickling process!
At Koshin Sangyo Co., Ltd., we conduct pickling treatment using immersion and spraying methods, utilizing the large 13m stainless steel pickling tank, one of the largest in western Japan. In iron pickling, it is possible to enhance rust resistance and paint adhesion by simultaneously forming a ferrous phosphate film on the surface during the pickling process.

Removal of floating rust, residual foreign substances, etc. from inside pipes, target equipment, heat exchangers, tanks, etc., and the ability to perform flushing and circulating acid cleaning to improve cleanliness.
At Koshin Sangyo Co., Ltd., we select chemicals and solvents primarily based on the degree of corrosion and contamination, focusing on acidic and alkaline solutions, to perform chemical cleaning (metal cleaning). We can remove floating rust, residues, and foreign substances from the interiors of pipes, target equipment, heat exchangers, and tanks, and we offer flushing and circulating acid cleaning to improve cleaning efficiency. Additionally, we also conduct on-site flushing and acid cleaning work. Please feel free to contact us if you have any requests. 【Processing Details (Partial)】 ■ Acid cleaning of iron ■ Acid cleaning of stainless steel ■ Chemical cleaning (regenerative cleaning) ■ Flushing and circulating acid cleaning ■ Pressure testing *For more details, please refer to the PDF document or feel free to contact us.
