Galvanized steel pipe is a welded steel pipe with a hot-dip or electro-galvanized layer
on the surface. Galvanizing can increase the corrosion resistance
of steel pipes and prolong their service life. Galvanized pipes are
widely used. In addition to being used as pipeline pipes for
general low-pressure fluids such as water, gas, and oil, they are
also used as oil well pipes and oil pipelines in the petroleum
industry, especially offshore oil fields, and oil heaters and
condensation pipes for chemical coking equipment. Pipes for
coolers, coal distillation washing oil exchangers, trestle piles,
and support pipes for mine tunnels, etc

1. Material preparation: Select high-quality steel as the base
material, and prepare the needed galvanized materials, pipe
fittings and tools.
2. Processing and production: the steel is cut into the appropriate
length, and stacked into a certain number according to the design
requirements, and then the steel is processed, including welding,
bending, punching and other processes. The processed steel pipe is
combined into a predetermined structure and connected with pipe
fittings.
3. Oil removal, pickling: the processed steel pipe will be removed
oil and pickling treatment, so that the surface can be better
bonded with galvanized materials.
4. Preheating treatment: the steel pipe after oil removal and
pickling treatment is preheated, and the steel pipe is heated to a
certain temperature to improve its surface quality and adhesion.
5. Galvanizing treatment: The preheated steel pipe is galvanized by
hot dip galvanizing and electroplating.
6. Inspection and quality control: quality inspection and control
of galvanized steel pipe to ensure its quality and national
standards and customer requirements.
7. Packaging and transportation: The galvanized steel pipe is
packaged and then transported.
