Technical Parameter of Galvanized Steel Pipe

Galvanized pipe, also known as galvanized steel pipe, is divided into two types: hot-dip galvanized and electro-galvanized. The hot-dip galvanized layer is thick and has the advantages of uniform coating, strong adhesion, and long service life. The cost of electro-galvanizing is low, the surface is not very smooth, and its corrosion resistance is much worse than that of hot-dip galvanized pipes.

Application of Galvanized Steel Pipe

Galvanized pipes have a wide range of uses. In addition to oil and other low-pressure fluid pipelines, it is also used as oil well pipes in the petroleum industry, especially in offshore oil fields, oil heaters in chemical coking equipment, coal distillation, and oil washing converter pipes, bridges, etc. Pipe pile, mining tunnel support frame with pipe, etc. Developed countries in the world started to develop new pipes and continuously banned galvanized pipes.

FAQs of Galvanized Steel Pipe

  • First, we use solvents to clean the surface of the steel to remove organic matter on the surface.
  • Then toolsare used by ours to remove rust (wire brush) to remove loose or inclined scales, rust, welding slag, etc.,
  • We use pickling.
  • Galvanizing is divided into hot-dip galvanizing and cold-dip galvanizing. Hot-dip galvanizing is not easy to rust, and cold galvanizing is easier to rust.

The spraying method for galvanized pipes can be carried out according to the normal spraying construction, following the process of surface treatment – spraying primer – spraying top coat. Scrub the surface of the substrate with solvent to remove oil and dirt, clean the substrate to ensure adhesion.
Spray ED1000 epoxy primer to reach the specified film thickness. After the primer is applied, the top coat is applied at an interval of 24 hours. The top coat is selected according to the actual use. For indoor environment, epoxy resin topcoat and polyurethane topcoat can be chosen. Outdoor environment can choose acrylic polyurethane topcoat, acrylic topcoat, fluorocarbon topcoat, and the coating can reach the specified film thickness.
Use phosphate primer or high adhesion primer. Now there is a phosphate primer on the market, its function is similar to the phosphate treatment, can improve the roughness of the zinc tube to a certain extent. Primer or direct use of an intermediate paint finish. Before painting the galvanized pipe, it needs to be lightly polished so as not to damage the anti-corrosion layer of the galvanized pipe itself. The treatment of the substrate and the choice of paint are key factors in avoiding paint flaking from galvanized pipes.
