We are a professional factory of welding pipe machine, and we commit ourselves to welding pipe machine research, development and production for several years.
This machine is common in daily life, and it’s a trend to produce oil casing with welding pipe machine, and it depends on its advantages. Generally, oil casing production process is hot rolling seamless steel pipe, also it can be welded. Welding method is more common. There is welding seam left if oil casing produced by welding method, so there are several important questions with this, whether obdurability of base material fits the pipe, weld gray spot, weld groove corrosion and so on. The questions mentioned above should be avoided during production.
What should we pay attention to when oil casing is produced in welding pipe machine? It should be obdurability. Cooling is controlled via hot tensile strength diameter decrement, and it helps a lot on welding seam and enhances the obdurability. Factors about weld gray spot are base welding material, welding temperature, welding speed and so on. So we should control strictly about strip end quality and welding process. Welding seam heat treatment and whole pipe heating before hot tensile strength diameter decrement can reduce and avoid weld gray spot. The control of weld groove corrosion can be avoided via hot tensile strength diameter decrement.
Our company aim is to service for our clients, provide high quality product, achieve a win-win situation. We are looking forward to cooperate with you!
