Surface Treatment

Ratan Tubes & Engineering offers specialized surface treatments to enhance durability, performance, and cleanliness. Our processes include:

• Bright Annealing – Performed in a vacuum or controlled hydrogen atmosphere to minimize oxidation and retain a bright, clean stainless-steel surface. This process produces a thin oxide layer and significantly improves corrosion resistance compared to open annealed and pickled tubes.
• Electropolishing – A controlled anodic process where material is selectively removed, eliminating crevices and producing an ultra-smooth, glossy surface. This enhances hygiene, reduces contamination risks, and increases resistance to corrosion.

Through these advanced treatments, we ensure that every tube and fitting meets the stringent requirements of critical industries.
