Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. is a high-tech enterprise specialized in the design, development and manufacture of welded pipe equipment, spiral welded pipe equipment, cold-formed steel equipment, sheet and pipe finishing equipment and high-precision slitting line equipment. Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. to introduce you to welded pipe mill in the production of oil casing pipe unit should pay attention to what the application in the manufacture of more pipe equipment, because the use of the advantages of welded pipe mill, and now also beginning to use welded pipe mill to produce oil casing. However, in the use of oil casing pipe production unit, when there are still many areas that need attention. Following on from the welded pipe mill manufacturers to introduce you need to pay attention to what sets when welded pipe mill to produce oil. Normally, with a welded pipe mill to produce oil sets in two ways, one is the use of hot-rolled seamless way, and another way is to pipe welding unit uses, but more commonly used approach is pipe welding unit. Because with welded pipe production unit of oil put back there is a seam welded precision equipment, so the base metal and the weld strength and toughness, gray leaf spot weld, the weld groove-like corrosion problems and other issues are the need to pay attention to avoid.

Taiyuan Huaxin Cheng electromechanical equipment for pipe welding occurs when you introduce slotted What are the reasons? Pipe welding equipment when they would often not have bonding together Longitudinal weld equipment, which is slotted problem, slotted length typically a few centimeters may also be more likely to have, like this product Quality will be unqualified phenomenon. Then slotted product causes what is it? Following on from the pipe equipment manufacturers to organize your presentation. The reason appears slotted pipe welding equipment problems are many, the first problem is the material pipe production equipment, and some chemical composition of raw materials will make the raw material base metal embrittlement occurs during welding causing slotted phenomenon after welding. If the welding time, all operations are in accordance with the normal circumstances, and pipe sizing process appears slotted problem, or rip the tube weld seam center deviation, these cases mostly because of the edge of the base metal stick Even the formation of irregular slit, and this phenomenon is mostly because of the chemical composition of raw materials caused. Longitudinal equipment _ _ Yunnan pipe Huaxin Cheng electromechanical equipment provided by the Electrical and Mechanical Equipment Co., Ltd., Taiyuan Huaxin Cheng.
