Metallic Zinc Coating
When metallic zinc spray is applied, the average mass of the zinc per unit area must be at least 130g/m², ensuring robust protection against corrosion.Additionally, there is a local minimum requirement of 110 g/m². Customized zinc mass specifications are also available to cater to specific customer needs.
Bitumen Coating
The bitumen coating should have an average thickness of no less than 70 μm, while the local minimum thickness should not fall below 50 μm. Custom thickness as per customer request is also offered.
Alternative Coating
Process and Testing Procedures:
1. Induction Furnace and Metal Treatment: Chemical analysis of raw materials, spheroidizing, and nodularity checks.
2. Casting: Performing visual inspections and weight checks to ensure quality.
3. Heat Treatment: Analyzing the microstructure to ensure durability.
4. Hydrostatic Test: Conducting pressure tests for integrity assurance.
5. Dimensional Checks: Verifying pipe length, joint integrity, outer diameter, wall thickness, and overall appearance.
6. Zinc Spraying: Ensuring proper thickness through rigorous testing.
7. Lining and Coating: Performing 100% visual checks and random thickness tests.
8. Marking and Packing: Conducting thorough visual inspections to ensure proper labeling and packaging.
