Surface Treatment Processes
1.Painting: Applying a paint layer to enhance the corrosion resistance and appearance of the steel pipe, suitable for various environments.
2.Plastic Coating: Coating the steel pipe surface with plastic for additional corrosion protection, enhanced wear resistance, and insulation.
3.Sandblasting: Using high-pressure sandblasting to clean the steel pipe surface, removing rust and impurities to improve the adhesion of subsequent coatings.
4.Annealing: Heating and slowly cooling the steel pipe to eliminate internal stress, enhancing its toughness and durability.

STEEL PIPE PROCESSES

1.Welded Pipe: Manufactured through welding processes, offering high strength and good sealing, suitable for various industrial applications.
2.Galvanized Strip Pipe: Made from galvanized strip steel, featuring strong corrosion resistance, suitable for high-humidity environments.
3.Hot-dip Galvanized Pipe: Achieved through two methods:
(1) Blow Galvanizing: Uses high-temperature gas to apply a zinc coating, providing uniform coverage, ideal for mass production.

(2) Hot Immersion Galvanizing: Involves immersing the steel pipe in molten zinc, resulting in a strong, adhesive zinc layer with excellent corrosion resistance.
