Galvanized Steel Pipes

Galvanized steel pipes, are also called Galvanized pipes, Gi pipes or pipes with zinc coating, widely are applied to different industries because of its excellent characteristic of steel such as durability, toughness, strength with low cost and high yield. So what exactly is galvanized steel pipe? Below is the detail from insider of senior steel manufacturer.

What is galvanized steel pipe?

So actually galvanized steel pipe is to be understood as seamless steel pipes or welded steel pipes with zinc coating treatment. According to crafts and process of galvanized seamless pipes,

• At the first, it should be preparation of pipe blanks, inspection method, heating, perforation, acid cleaning, pickling and passivation, hot rolled or cold rolled method, cutting pipes end, polishing inner and outer of pipes, labeling and packaging.
• The second, hot dipped or zinc electroplating are mainly two methods for steel pipes with coating process.

Advantages of galvanized steel pipes

Galvanized steel pipes own more advantages in contrast with uncoated steel pipes or stainless steel pipes and so on no matter from cost of galvanized pipe, its value and GI pipes’ steel features.

• Galvanized steel pipes are low cost when compare with stainless steel materials.
• Galvanized steel pipes feature anti rust, resistance of corrosion, waterproof and weather resistance when consider the uncoated steel pipes with lack of these characteristics.

Usage of galvanized steel pipe

As the surface zinc coating, galvanized steel pipe is widely used in construction, machinery, below is the list of related applied products:

1. agricultural machinery,
2. petroleum machinery,
3. exploration machinery.

In addition, it also is involved in railway vehicles, chemical industry, electric power, coal mine, automobile industry, sports facilities, highway and bridge industries, etc because it is more resistance of corrosion, rust comparing with uncoated steel pipes.

Specification of galvanized steel pipes

There are so many specification of galvanized steel pipes. However, it is suitable for different region according its specific standards and specifications, such as in China, metric system is the standard of measurement, however British system is more suitable for Europe countries.

• Length, both of British and metric system

21’ – 1,200cm

07’ – 600cm

• Nominal wall thickness

2.0 mm, 2.5 mm, 2.8 mm, 3.2 mm, 3.5 mm, 3.8 mm , 4.0 mm, 4.5 mm
