Galvanized pipe is a galvanized pipe made by bending a strip or coil into a spiral shape and welding the inner and outer seams with double-sided submerged arc automatic welding. It can be widely used in the manufacturing industries of construction, machinery, coal mining, chemical industry, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, etc. due to the following reasons. The following small talk about the advantages and disadvantages of galvanized pipe is what?

Advantages and disadvantages of galvanized pipes

1. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Galvanized pipe substrate and the molten plating solution undergo a complex physical and chemical reaction to form a corrosion-resistant, tightly structured zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate. Therefore, its corrosion resistance is strong.

2. As long as the forming angle is changed, it is possible to produce various calibers of steel pipes with the same width of strip steel, and it is easy to adjust the shape.

3. because of continuous bending forming, the length of spiral pipe is not limited, the length can be set at will.

4. the spiral shape of the welded seam is evenly distributed throughout the circumference of the spiral pipe, so the spiral pipe has high dimensional accuracy and strength.

5. easy to change the size, suitable for the production of small quantities and many varieties of spiral pipes. The weld seam of galvanized pipe is longer than the weld seam of straight seam pipe of the same specification. With the same specification wall thickness, hot-dip galvanized steel pipe can bear the greatest pressure.

Advantages and disadvantages of galvanized pipes

6. Galvanized steel pipe with hot dip or electro galvanized layer on the surface of the welded steel pipe. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life.

Regarding the advantages and disadvantages of galvanized pipes, the following editorial continues to introduce you. The defect of the weld seam of galvanized pipe is “oblique defect”. In the process of use, the main stress direction of the steel pipe, that is, the length of the equivalent defects in the direction of the axis of the steel pipe is smaller than the straight seam pipe; secondly, because the pipeline steel are rolled steel, impact toughness has greater anisotropy, the CVN value of the rolling direction can be higher than the CVN value perpendicular to the rolling direction of three times.

Galvanized pipe advantages and disadvantages can only be known in the use of comparison, galvanized pipe can be detected through the data indicators after use, so here you can only provide you with theoretical advantages and defects of galvanized pipe, everything or real user feedback provided by the main.
