Q:What is the manufacturing process of galvanized steel pipes?

1. Material preparation: Use high-quality steel as the base material and prepare the required galvanized materials, pipe fittings, and tools.

2. Processing and production: Cut the steel into appropriate lengths and stack them into a certain number according to the design requirements, and then process the steel, including welding, bending, drilling, and other processes. Combine the processed steel pipes into a predetermined structure and use pipe fittings to connect them.

3. Degreasing and pickling: The processed steel pipes are degreased and pickled so that the surface can be better bonded to the galvanized material.

4. Preheating treatment: Preheat the steel pipe that has been deoiled and pickled, and heat the pipe to a certain temperature to improve its surface quality and adhesion.

5. Galvanizing treatment: The preheated steel pipe is galvanized through two methods: hot dip galvanizing and electroplating.
