9. Professional FAQ: Stainless Steel Water Tank Technical Terms

Q1: What is the difference between SS304 and SS316L for large square water tanks?

A: Both are high-grade austenitic stainless steels. SS316L offers better resistance to chlorides, acids, and extreme environments due to its molybdenum content and low carbon. For coastal, food, or pharmaceutical uses, SS316L is recommended for prolonged service life and anti-corrosion.

Q2: How are tank capacities calculated for irregular plant rooms?

A: Custom large square water tanks are designed modularly. Engineers use panel sizing (typically 1000x1000mm units) and stack configuration (height, width, depth) to maximize fit and net capacity. 3D scan and CAD design ensure space efficiency with site constraints.

Q3: What leak and pressure tests are conducted?

A: Every tank is subjected to hydraulic pressure testing (usually 1.2-1.5x working pressure) and 48h water-tightness test. Results are recorded via manometer and ultrasonic thickness gauge, following ISO 19901-5 and local QA protocols.

Q4: Are tanks certified for potable water and food contact?

A: Yes, all tanks are manufactured from food-grade stainless steel compliant with ISO 9001/22000, FDA, and ANSI/NSF 61. Factory QA ensures no leaching or contamination per EN 10312 and GB 9684.

Q5: What are typical panel thicknesses, and why do they matter?

A: Standard panel thickness ranges from 1.5mm (for small/medium tanks) to 6mm (for large/industrial tanks). Thicker panels enhance compressive strength, seismic safety, and longer lifespan, especially for rooftop/outdoor installations.

Q6: How is on-site installation performed?

A: Modular panels are transported flat-packed, then assembled onsite using stainless bolts, gaskets, and seam/spot welding. Installation follows GB 50106 & local safety standards, with clean-room assembly for food/pharma tanks.

Q7: What is the maintenance frequency for stainless steel water tank rectangular units?

A: Minimal: Internal cleaning and health inspection are recommended annually. Tanks exceeding 10 years may require ultrasonic thickness checks and panel seal replacement every 5 years, with full documentation available for hygiene audits.
