How to maintain hot-dip galvanized steel pipe
Date:2020-09-24      Views:246Time      Label:How to maintain hot-dip galvanized steel pipe

Hot-dip galvanized steel pipes are widely used in industrial production, mainly due to their good performance. To give full play to the good performance of seamless steel pipes, it is sometimes necessary to galvanize the hot-dip galvanized steel pipes. After all, after mass production of seamless steel pipes, all seamless steel pipes can be sold in a short time, and corresponding processes are required in this process. Effective protection is essential.


When the hot-dip galvanized steel pipe is being cleaned, it is necessary to prevent adding a cleaning agent to the water. When cleaning, many people don't understand how to clean the hot-dip galvanized steel pipe. As a result, they choose to use a strong cleaning agent to remove the stains on the hot-dip galvanized steel pipe. This is not scientific enough.


1. Wearing labor protection products before pickling.

2. A detailed inspection should be carried out on the working environment on site, mainly to check that the sling steel pipe is intact before continuing to work, and the cleaning operation can be started after confirmation.


Clean water cleaning uses clean water to rinse the inner wall of the steel pipe, but for impurities such as calcium, magnesium ion scale and biological clay attached to the inner wall of the hot-dip galvanized steel pipe, the clean water cleaning effect is not obvious. When cleaning the hot-dip galvanized railing, there will be a coating on the outside of the hot-dip galvanized railing. The cleaning agent will be low in price and the friction between the brush and the railing will affect the cleaning effect. The chemical substances contained in it will also directly cause the outer layer to fall off, which will directly reduce the service life of the galvanized pipe and reduce the safety effect. Chemical reagents are added to the chemical cleaning water, but the chemical composition is corrosive to the steel pipe and shortens the service life of the steel pipe. This is a method of fishing in dry water, which is not desirable.
