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 electromechanical equipment for your weld quality defects and the reasons elaborated analysis welded steel pipe equipment when lap welding refers to two edge dislocation in the tube welding, deburring go even hang one can see traces of dislocation pipe unit, The ride will be the main reasons for poor weld quality molding; extrusion production of thin-walled tubes improper pressure; squeeze roller installation uneven, one high and one low; adverse strip slitting edge welded pipe mill equipment, curling or edge burr too large and so on. Above is on pipe welding process equipment prone to cracks and take some welding defects such as cause analysis, and I hope you can help. 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 electromechanical equipment for you to resolve welded pipe mill in the production of oil casing pipe unit should pay attention to what the oil in the production casing first thing to note is that the strength and toughness in the production process through hot stretch reducing controlled cooling pipe unit price, so the child can largely improve the welded pipe mill welding on oil casing pipe unit left the factory weld problems, while enhancing the strength and toughness. The main factor in the formation of gray leaf spot weld tubing and casing include the chemical composition of the base metal welding temperature, welding speed welding. Wants to avoid the production of gray leaf spot welds, we should pay attention to strict quality control strip edge and welding technology, the use of pre-weld heat treatment and hot stretch reducing whole tube heating method to avoid the oil casing seam ash spots appear. Pipe welding unit wants to avoid the production of oil casing shaped groove weld corrosion can occur by thermal tension reducing methods to avoid.
