Metallic Zinc Coating
When a metallic zinc spray is applied, the average mass of the zinc per unit area is ensured to be no less than 130g/m².With a localized minimum of 110 g/m², we also offer the option to customize the zinc mass according to customer specifications.
Bitumen Coating
The average thickness of the bitumen coating shall be no less than 70 μm, with a local minimum thickness of at least 50 μm. Custom thickness options are available to meet specific customer requirements.

Process and Testing:
1. Induction Furnace and Treated Metal: Includes chemical analysis of raw materials, spheroidizing, and nodularity checks.
2. Casting: Conduct visual inspections and weight checks to ensure quality.
3. Heat Treatment: Inspect the microstructure to confirm the material's integrity.
4. Hydrostatic Test: Perform pressure tests to guarantee durability.
5. Dimensional Checks: Verify the pipe length, joint, outer diameter, wall thickness, and overall appearance.
6. Zinc Spraying: Conduct thickness tests to ensure proper coating.
7. Lining and Coating: Perform 100% visual checks and random thickness testing.
8. Marking and Packing: Ensure 100% visual inspections for accuracy.
