Galvanized Layer Thickness Standard of Galvanized Pipe

According to national standards, the galvanized layer thickness of galvanized pipes has strict requirements. Let’s take a look together!

The thickness of the galvanized layer of galvanized pipes is based on the environment and requirements of its use. According to national standards, the galvanized layer thickness of galvanized pipes should meet the following criteria:

1. For workpieces with a thickness ≥ 6 millimeters, the average galvanized layer thickness should be greater than 85 micrometers.

2. For workpieces with a thickness less than 6 millimeters but greater than 3 millimeters, the average galvanized layer thickness should be greater than 70 micrometers.

3. For workpieces with a thickness less than 3 millimeters but greater than 1.5 millimeters, the average galvanized layer thickness should be greater than 55 micrometers.

4. For workpieces with a thickness less than 1.5 millimeters, the local galvanized layer thickness should be greater than 45 micrometers.

It is noted that the above standards do not include galvanized layers that have undergone centrifugal separation treatment.

So, through the article, do you have a better understanding of the galvanized layer thickness standards for galvanized pipes? Here, we adcised you to pay attention to whether the thickness of the galvanized layer complies with national standards when purchasing galvanized pipes to ensure that their products can meet the required anti-corrosion requirements.
