Many of our common galvanized pipes are processed and produced by high frequency Straight seam welded pipe equipment. Some welds are black and rusty, and some seem to be a white line, which has become zinc supplement in the industry. For unprofessional personnel, one question to ask is whether this galvanized line belongs to hot galvanizing or cold galvanizing?

The function of zinc supplement for high frequency Straight seam welded pipe equipment is to prevent the oxidation of the weld from being unprotected and modified during the processing and forming of galvanized pipe. The welded pipe weld is cleaned of the weld residue by scraper, and then zinc supplement is carried out online and cooled in the water cooling link, so as to obtain a non exposed galvanized pipe.

Here, the process of adding zinc layer at the weld position is called zinc supplement, which belongs to cold plating process, not hot plating process. The two are different, but the galvanized steel coil for processing this pipe is indeed hot-plated. I hope you can understand that if you want to purchase high frequency Straight seam welded pipe equipment, you can contact us.
