Superior Metallic Zinc Coating
When the metallic zinc spray is meticulously applied, the average mass of zinc per unit area must be at least 130g/m²,with a localized minimum of 110g/m². We also offer customization of zinc mass according to your specific requirements.
Robust Bitumen Coating
The mean thickness of our bitumen coating is guaranteed to be no less than 70 μm, with a local minimum thickness of at least 50 μm. Custom thickness specifications are available upon request.
Versatile Alternative Coating Solutions
Thorough Process and Testing Procedures:
1. Induction Furnace and Treated Metal (includes detailed chemical analysis of raw materials, spheroidizing & nodularity checks)
2. Casting (comprehensive visual inspection and weight verification)
3. Heat Treatment (analyzing microstructure for quality assurance)
4. Hydrostatic Test (stringent pressure testing)
5. Dimensional Checks (ensuring accurate pipe length and joint, outside diameter, wall thickness, and overall appearance)
6. Zinc Spraying (precision thickness testing)
7. Lining and Coating (100% visual inspection and random thickness testing)
8. Marking and Packing (100% visual quality check)
