Production Flow
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.
Advantages of TYT
1.The quality of steel pipe raw material is difference from other supplier.We have stable raw material supplier.We won't change the supplier because of the price.So the quality will be almost same.
2.Welded technology is different.
3.The zinc wire for zinc supplement is different.
4.Water cooling in the process of produce is different.
5.The passivation water is good quality,different from others.
6.The speed of producing will influence the pipe body temperature.
