Application:

1. Building water supply and drainage:

It is used to transport tap water and wastewater.

2. Fire protection system:

As a fire water pipeline.

3. HVAC:

It is used for the transmission of heating and cooling air.

4. Agricultural irrigation:

Ensure the distribution of irrigation water to farmland.

5. Gas transmission:

Transporting natural gas and other gases.

6. Factory piping:

It is used for the transportation of liquids and gases in various factories.

7. Build scaffolding:

Provide a stable support structure.

Physical properties of galvanized steel pipe:

1. The density is large, about 7.85 g/cm3. 2. It has a certain strength and rigidity, and can withstand certain pressure and external force. 3. The thermal conductivity is low, and the thermal insulation performance is relatively good. 4. The galvanized layer on the surface makes it have good wear resistance.

Chemical properties of galvanized steel pipe:

1. The galvanized layer provides good corrosion resistance, which can effectively prevent the steel pipe from rusting in normal environment. 2. It has a certain resistance to common acid and alkali solutions, but it may still be eroded in strong acid and alkali environment. 3. The galvanized layer can prevent the steel pipe from chemically reacting with external substances to a certain extent.
