Metallic Zinc Coating
When metallic zinc spray is applied, the average mass of zinc per unit area shall be no less than 130g/m², ensuring optimal protection and durability.This coating must maintain a local minimum of 110g/m². Custom zinc mass adjustments can be made according to the customer's specific requirements.
Bitumen Coating
The average thickness of the bitumen coating shall be no less than 70 μm, with the local minimum thickness not falling below 50 μm. Custom thickness adjustments are available based on customer preferences.
Alternative Coating
Process and Testing:
1. Induction furnace and treated metal: Includes chemical analysis of raw materials, spheroidizing, and nodularity tests.
2. Casting: Involves a thorough visual check and weight assessment.
3. Heat Treatment: Examination of microstructure to ensure quality.
4. Hydrostatic Test: Pressure testing for reliability.
5. Dimensional Checks: Verification of pipe length, joint, outer diameter, wall thickness, and overall appearance.
6. Zinc Spraying: Thickness testing to meet standards.
7. Lining and Coating: 100% visual inspection complemented by random thickness testing.
8. Marking and Packing: Comprehensive visual checks to ensure proper marking and packaging.
