Galvanized steel pipes are welded steel pipes with hot dip or electrogalvanized layers on the surface. The galvanized pipe is a combination of a molten metal and an iron matrix to produce an alloy layer, thereby combining the substrate and the plating.
Customized Pre-galvanized Welded Tube For Sale Production Process Flow Chart . The process of steel pipe production is as below.First,we should uncoiling the galvanized steel strip,then carry out cutting& butt welding,then the galvanized steel strip enter the storage box,the machine will make it forming,then welding into steel pipe,then do zinc supplement in welded seam,then water cooling.The square tube should be reforming,then sizing
Welded pipe starts out as a long, coiled ribbon of steel called a skelp. The skelp is cut to the desired length, resulting in a flat rectangular sheet. The width of that sheets shorter ends will become the pipe' outside circumference, a value that can be used to calculate its eventual outside diameter.
