welded stainless steel tanks manufacturing process

Material selection

Only certified SUS304 stainless steel is used to ensure strength, hygiene, and corrosion resistance. COFF verifies every batch through third-party inspection before production begins.

Plate cutting and forming

High-precision CNC cutting and rolling machines shape the steel plates to exact specifications. COFF maintains tight dimensional tolerances to ensure smooth assembly and uniform tank geometry.

TIG welding and assembly

All components are joined using TIG welding by ASME-certified welders. COFF performs real-time inspection to ensure clean welds, full penetration, and no contamination for lasting durability.

Surface polishing and passivation

Interior and exterior surfaces are mechanically polished to achieve mirror or matte finishes. COFF polishing stainless steel tanks applies chemical passivation to enhance corrosion resistance and hygiene.

Pressure and leak testing

Each welded stainless steel tank undergoes hydrostatic and pneumatic tests. COFF conducts at least two full operation tests before delivery to verify structural strength and sealing performance.

Final inspection and certification

Before shipment, every precision stainless tank is inspected for weld quality, finish uniformity, and dimensional accuracy. COFF provides complete FAT documentation and quality certificates.

common faq about tank stainless steel

how to clean stainless steel tanks

Cleaning stainless steel tanks requires a combination of mechanical and chemical methods. Begin with a thorough warm water rinse to remove residue, then apply a suitable food-grade detergent or CIP (clean-in-place) system. Use soft brushes or cloths to avoid scratching surfaces. For SUS304 stainless steel, mild acids like citric acid help remove light stains without damaging the tank. Carbon steel or coated tanks may require neutral pH cleaners to prevent corrosion or coating damage. After cleaning, rinse thoroughly with clean water and dry. COFF tanks feature smooth interiors and accessible ports, simplifying cleaning and maintaining hygiene across industries.

Is stainless steel good for water tanks?

Yes, stainless steel is an excellent material for water tanks. Here’s why:

Corrosion resistance – Stainless steel, especially SUS304, resists rust and corrosion, ensuring long-term durability even with constant water exposure.

Hygiene – Its smooth, non-porous surface prevents bacterial growth, keeping potable water safe.

Strength and durability – Stainless steel water tanks withstand pressure, impact, and environmental stress without deforming.

Temperature stability – Stainless steel maintains structural integrity and resists thermal expansion or contraction, making it ideal for environments with wide temperature fluctuations.

Longevity and sustainability – Properly maintained stainless steel water tanks can last decades, are recyclable, and do not leach chemicals.

Environmentally friendly – Fully recyclable and does not leach chemicals into water.
