Galv steel pipes are widely used in industrial production, mainly due to their good properties. In order to give full play to the good performance of seamless steel pipes, it is sometimes necessary to galvanize galv steel pipes for protection.

1. Maintenance method of galv steel pipe

After the galv steel pipe has been used for a period of time, it is necessary to check whether the galvanized layer on the surface of the galvanized pipe is damaged or rusted. Timely maintenance can help extend the life of the steel pipe. Maintenance can be done with hot-dip galvanized special repair paint to avoid peeling of the coating.

When cleaning galv steel pipes, it is necessary to avoid adding cleaning agents to the water. When cleaning, many people do not understand the truth very well. It is not scientific enough to use strong detergents to remove stains. There will be a coating on the outside of the galv steel pipe, and the cleaning agent will reduce the friction between the brush and the guardrail, which 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.

In fact, if we want to use the galv steel pipe for a longer time, our usual maintenance is indispensable. The galv steel pipe can be pickled, which is mainly to remove some stains on the surface of our hot-dip galvanized square pipe. But after pickling, we also let them go through an ammonium chloride or zinc chloride aqueous solution for another cleaning, and then put them in the hot dip plating tank. After such maintenance steps, galv steel pipes can be used for a long time.

2. What problems should be paid attention to when pickling galv steel pipes?

First of all, good labor protection products must be worn before pickling. The on-site working and living environment should also be continuously inspected in detail, mainly by checking whether the sling of the galv steel pipe is in good condition.

Some workers also need to understand the acid concentration and temperature changes and the tonnage of the pickling pipe in this tank before operation. After confirming that it is in good condition, the work can be carried out. When pickling in the second pickling of hydrochloric acid, the content of hydrochloric acid is generally 18% to 20% is preferred. These can be detected using professional measuring equipment.

The time for pickling galv steel pipe is 5 to 15 minutes. We need to adjust the time according to the weight. The weight is preferably controlled between 2-5 tons. During the vibration period, the steel pipe needs to be pickled frequently. When the pipe is put into the acid tank, it is an inclined steel pipe to prevent the hydrochloric acid from accidentally hurting people.

Galv steel pipes have been widely used in industrial production. It is precisely in order to give full play to the good performance of galv steel pipes, sometimes we need to maintain galv steel pipes. After all, sometimes after a large amount of galv steel pipe is produced, it may be difficult to sell it in a short period of time, so effective protection is indispensable.
