What is Pipe Number ?
As we all know, in steel industry, there is heat number. And in every heat, there are many coils or plates, then there will be coil number or plate number. With those coils or plates, HYSP produce API 5L Line Pipe, A53 Steel Tube, A252 Piling Pipe, Structure Steel Pipe, and to mark every pipe we produce and for trace purpose, we will mark one unique pipe number on the surface of our ERW welded pipe. Every pipe number is unique and traceable to the coil or plate number and then heat number. Those numbers are connected and with one of them, the rest is traceable.
