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&straightening,then cutting into required length,then marking,then passivation and oiling to prevent the pipe from rusting.Finally,we will packing the pipe and taging,then weight checking and trucking.
We have own laboratory to make various testing to control the quality.
