Forming:The material will be extruded by many groups machines to form into the round tube embryo. It is easy to understand this processing. In this way, the pipe welding will be easier to proceed at a high speed.
Then is Welding:Pre-galvanized pipe is ERW steel pipe. Electric resistance welding (ERW) is a welding process where metal parts in contact are permanently joined by heating them with an electric current, melting the metal at the joint.
About this part, we have big advantages compared to the small factories. Our factory uses the latest welding machines. The cost is four times as the ordinary equipment, so the producing speed is faster and product quality is much better. And we will repair and replace the new machines in a regular time.
This is why usually we have a short delivery time.
