Steps to determine the quality of hot-dip galvanized square pipe

In order to improve the performance of the square tube, the square tube can be hot-dipped galvanized. Hot-dip galvanizing is a heat treatment technique. In order to meet the requirements during the hot-dip galvanizing of square tubes, continuous inspections are required. If the quality of the tube is not measured, there will be many effects.

The first requirement of the inspection is the adhesion ability, that is, the thickness of the galvanized hot-dip galvanized square tube. Since the galvanized layer of the hot-dip galvanized square pipe is the place that determines whether it meets the anti-corrosion requirements, professional measuring tools can be used in the inspection process. During the inspection process, the thickness of the galvanized layer of the hot-dip galvanized square pipe has certain regulations, and it needs to be marked according to these regulations when using it.

Secondly, the basis of inspection is uniformity, that is, the thickness of the galvanized layer. In order to improve the application quality of the hot-dip galvanized square tube in the inspection process, the thickness after manufacturing can meet the application specifications, so that there will be no damage during the application process.

Finally, in the inspection process, it is necessary to check its firmness, that is, the accuracy of contact between the square tubes. If the precision of the hot-dip galvanized square pipe is too poor during use, the galvanized layer will fall off during use, causing corrosion by other objects during use, and the hot-dip galvanizing square pipe cannot be used normally. In the inspection process, the simplest method can be used for inspection, that is, two hot-dip galvanized square pipes are knocked against each other. If they have outstanding characteristics, they will not be damaged, and the quality must be problematic.
