Metallic Zinc Coating
When a metallic zinc spray is applied, the average mass of the zinc per unit area must be at least 130g/m², ensuring robust corrosion protection.The local minimum mass should not be less than 110 g/m². Custom zinc mass specifications are also available upon request.
Bitumen Coating
The average thickness of the bitumen coating should be no less than 70 μm, with a local minimum of at least 50 μm. Custom bitumen thickness specifications can be provided upon request.
Alternative Coating
Process and Testing:
1. Induction Furnace and Treated Metal: Conduct chemical analysis of raw materials, spheroidizing, & nodularity assessments.
2. Casting: Perform visual inspections and weight checks to ensure precision.
3. Heat Treatment: Analyze microstructures for consistency and quality control.
4. Hydrostatic Test: Conduct pressure tests to verify the pipe's integrity and durability.
5. Dimensional Checks: Verify pipe length, joint dimensions, outer diameter, wall thickness, and overall appearance.
6. Zinc Spraying: Measure coating thickness to meet strict standards.
7. Lining and Coating: Perform 100% visual checks with random thickness testing to ensure quality.
8. Marking and Packing: Execute 100% visual inspections to guarantee perfect labeling and secure packaging.
