Metallic Zinc Coating
When a metallic zinc spray is applied, the average mass of zinc per unit area shall be no less than 130g/m2, ensuring optimal protection.Moreover, there is a local minimum of 110 g/m2 to guarantee comprehensive coverage. We also tailor the zinc mass according to your specific requirements.
Bitumen Coating
The bitumen coating must have an average thickness of at least 70 μm, with a local minimum thickness of 50 μm to ensure durability. Custom thickness variations are available upon request.

Process and Testing Details:
1. Induction Furnace and Treated Metal (Includes chemical analysis of raw materials, spheroidizing, and nodularity checks)
2. Casting (Visual inspections and weight checks are conducted)
3. Heat Treatment (Microstructure analysis)
4. Hydrostatic Test (Pressure testing of the pipes)
5. Dimensional Checks (Inspection of pipe length, joint, outer diameter, wall thickness, and overall appearance)
6. Zinc Spraying (Thickness testing to ensure consistency)
7. Lining and Coating (100% visual inspections and random thickness tests)
8. Marking and Packing (Thorough visual checks before packaging)
