Galvanized steel pipe is in the surface layer of steel plus a layer of galvanized layer, because this kind of tube surface processing galvanized, effectively prevent steel corrosion, rust and other phenomena, but also help prolong the use time of steel.

1. What is hot dip galvanized steel pipe?

As shown in the picture, this is galvanized pipe with a layer of galvanized surface. Galvanized steel pipe appearance is smooth, silver white.

Hot-dip galvanized steel pipe, also known as hot-dip zinc pipe, is a method by which steel components are immersed in molten zinc to obtain metal coating. With the rapid development of high-voltage power transmission and transportation, the protection requirements of iron and steel components are becoming higher and higher, and the demand for hot-dip galvanizing is also increasing. Usually the thickness of electrogalvanizing layer is 5μm-15μm, and the hot galvanizing layer is generally above 35μm, even up to 200μm. Hot dip galvanized coating ability, compact coating, no organic inclusion.

2. Classification

Galvanized steel pipe can be divided into cold galvanized steel pipe, hot galvanized steel pipe.

As shown in the picture, this is cold galvanized pipe. The galvanized layer is applied to the surface by means of coating, forming a protective layer after drying.


Cold galvanized steel pipe is also called electric galvanized, galvanized quantity is very little. Because the zinc layer is thinner than the zinc layer is easy to fall off, its corrosion resistance is poor. It is forbidden to use cold galvanized steel pipes as water pipes in new residential buildings.

As is shown in the picture, this is hot-dip galvanized steel pipe. Hot dip galvanized surface has a complete galvanized layer, no dark spots and bubbles. Hot dip galvanizing is more resistant to corrosion.

 

Hot dip galvanized tube is to make molten metal and iron matrix reaction and produce alloy layer, so that the matrix and coating of the combination of the two. Complex physical and chemical reactions occur between hot dip galvanized steel tube and molten plating solution to form a tightly structured zinc-ferroalloy layer with corrosion resistance. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

3. What specifications does galvanized steel pipe have?

The general specifications of galvanized steel pipe are :DN15 outer diameter is 21.3mm,DN20 outer diameter is 26.9mm,DN65 outer diameter is 76.1mm and so on. It is mainly divided into cold galvanized pipe and hot galvanized pipe, hot galvanized steel pipe is widely used in fire, power and highway. The Philippines in recent years to vigorously develop infrastructure, steel demand is large.As a professional steel supplier, we will provide quality galvanized steel pipe, galvanized steel pipe model complete. Have sufficient inventory.

4. Production steps of galvanized steel pipe

Black parts inspection → hanging material → degreasing → rinsing → pickling → cleaning → dipping agent → hot air drying → hot dip galvanizing → cooling → passivation and rinsing → unloading → inspection, dressing → packaging warehousing and transportation.


5.What is galvanized steel pipe used for commonly?

Welded steel tubes with hot dip or electrogalvanizing coating. Galvanizing can increase the corrosion resistance of steel pipe and prolong its service life. Galvanized pipe USES is very wide, in addition to a general low pressure fluid such as water, gas, oil line pipe, also used as oil industry, especially the ocean oil field oil well pipe, oil pipe, chemical coking equipment of oil heater, the condensing, exchange of coal distillation wash oil cooler for tube, and trestle pile, mining tunnel supporting frame tube, etc.
