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 华欣诚 you elaborate quality of welding defects and their causes Causes There are many cracks in welded leveler, including aspects of materials, molding and pass welding process parameters. Welded steel raw materials, the various elements contained in the steel has a direct impact on the overall weldability. For example, to the carbon content, when the carbon content of 0.65% when the upper limit of -0.70%. If the carbon content of the steel exceeds this limit, then weld it easy to rattle after straightening machine manufacturers, it is prone to cracks. 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 production of more and more purchases leveler, because the use of the advantages of welded pipe mill, and now gradually began using 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 there are two ways to set Buying leveler, one is the use of hot-rolled seamless way, and another way is to pipe welding unit uses, but more commonly used way is to pipe welding unit. Because with welded pipe production unit has an oil put back seam, so the base metal and the weld strength and toughness, gray leaf spot weld, the weld groove-like corrosion problems are need to pay attention to avoid problems.
