A Guide to Stainless Steel Water Tank Technical Requirements (Part One)
As for stainless steel water tanks, compliance with key regulations is non-negotiable. Explore essential criteria, from securing sanitary licenses to ensuring material quality and structural integrity. Join us in this quick guide for a concise overview of the regulatory landscape governing stainless steel water tank production and installation.
1. Sanitary License Requirement: Manufacturers must secure a sanitary license for stainless steel water tanks from China's National Health and Family Planning Commission.
2. Type Inspection Report: A type inspection report for stainless steel water tanks must be issued by a state-recognized authoritative organization.
3. Product Inspection Report: Equipment manufacturers are obligated to provide a product inspection report.
4. Material Standards Compliance: Materials used in production must meet drinking water hygiene standards, supported by quality documents and relevant tests.
5. Dimensional Compliance: Water tank dimensions, piping positions, and dimensions must align with design drawings and specifications.
6. Structural Design: Stainless steel water tanks should adopt a convex spherical combined welding structure or fabricated structure.
7. Material Adherence: The material of the water tank must meet or exceed bidding requirements.
8. Reinforcement Criteria: Reinforcing rebars in the water tank must have sufficient rigidity and proper arrangement, using matching materials.
9. Rebar Arrangement Considerations: The arrangement of reinforcing rebars should not hinder tank cleaning, fitting installation, or inspection.
10. Tank Base Specifications: The water tank base must use hot-dipped galvanized channel steel, meeting structural and strength requirements.
11. Manhole and Ladder Requirements: Water tanks should have manholes and ladders according to drawings and site conditions.
12. Welding Method Mandate: Stainless steel welding must exclusively use argon-arc welding.
13. Bolt Fastening and Treatment: The water tank base should be assembled with bolt fastening, with fasteners treated for corrosion resistance.
14. Post-Welding Inspection: After welding, all connecting parts must exhibit no loosening or leakage.
15. Welding Seam Standards: Welding seams must be full, with smooth outer surfaces and no defects, dents, or risks of hand cutting. Polishing of weld joints is required.
