Application:

1. Construction sector:

It is often used to build scaffolding, building structure support, plumbing systems, etc. For example, in residential water supply and drainage pipes, galvanized steel pipes can effectively prevent pipeline corrosion and ensure the normal transportation of water.

2. Fire Engineering:

As the main pipe of fire sprinkler system and fire hydrant system, because of its high strength and corrosion resistance, it can ensure a stable supply of fire water in case of fire.

3. Gas transportation:

4. Industrial sector:

It plays a role in the factory’s ventilation system, material transportation pipelines, etc.

Physical properties:

1. The appearance is usually silvery white, with a smooth surface.

2. It has high strength and hardness and can withstand certain pressures and external forces.

3. Excellent ductility and machinability, allowing for processing operations such as bending and cutting.

Chemical properties:

1. The galvanized layer provides good corrosion resistance, and the zinc oxide protective film formed by zinc in the air can prevent further oxidation of the steel pipe.

2. The galvanized layer has good stability in general acid and alkali environments, but corrosion may still occur under strong acid and alkali conditions.

3. Zinc is more reactive than iron, and in the event of corrosion, zinc is oxidized first to protect the steel tube matrix.
