Our products all have pretty physical appearance with smooth outside welding. Compared with some other suppliers, we use a flat knife for scraping the weld line. Besides, the visual weld geometry size is in line with the actual requirements of different applications. On the other hand, tube shape mutation is easy to cause stress concentration. If the excess part of the welding is polished off in the pipe production process, this will somewhat eliminate part of the stress concentration. In addition, our workers are all skilled in the post treatment of pipes, who all have excellent professional experience for many years.

With reference to pre galvanized steel pipe, before the zinc repair in the welding, we will first set out to remove the welding slag, zinc oxide skin and burned out layer. Then we use the spray painting for the repair of the zinc layer. We have the zinc repair in the welding close to the whole weld body in color, as a result of little color difference. Our finished galvanized pipe looks like much nature itself without blemish .
