FAQ: Technical Terms & Best Practices for Large Square Water Tanks

1. What are the main materials used in large square water tanks manufacturing?

Primarily food-grade SS304 and SS316L stainless steel, offering high mechanical strength and superior corrosion resistance. For corrosive or saline conditions, SS316L is standard; SS304 suffices for most potable and industrial water.

2. How is panel thickness determined for stainless steel water tank rectangular configurations?

Panel thickness (2.0-8.0 mm) is calculated based on tank height, design pressure (per ASME or EN standards), and site seismic/wind loads. Thicker base panels counteract hydrostatic and external forces.

3. What weld types and standards are applied?

TIG (tungsten inert gas) or argon arc welding ensures leak-proof, sanitary joints. All welds are visually, dye penetrant, and hydrostatically tested to ISO 5817-B and ANSI/NSF standards.

4. What installation standards and guidelines should be followed?

Installations comply with local codes (e.g., AWWA D103 for steel water tanks), manufacturer specs, and base foundation must be level with sufficient load-bearing. Earthquake zones require anchoring and expansion joint design.

5. How is life expectancy estimated for these tanks?

Typical life is 30-35 years for SS tanks (see reference), extendable with annual inspection (corrosion/scale check), proper cleaning, and prompt gasket replacement.

6. What testing and quality certifications should be required?

Reputable manufacturers offer ISO9001/14001, ANSI/NSF 61 or FDA certificates for potable use, with batch inspection certificates, hydrostatic, and leakage test reports per EN12566 or AWWA standards.

7. Are there recommended practices for tank cleaning & maintenance?

Annual cleaning (manual or CIP), scale/sediment removal, routine gasket/panel check, and disinfecting per WHO/CDC protocols preserve hygiene and structural integrity.
