Taiyuan Huaxin Cheng electromechanical equipment for you to resolve key issues in Shanxi unit production Longitudinal gray leaf spot weld seam gray leaf spot is present in the weld fusion line slitting line factory defect plane, the fracture was generally flat gray porphyritic, generally circular, oval or elongated. Gray leaf spot on the chemical composition of the weld zone, morphology, stress distribution influenced slitting, seriously affect the mechanical properties of the oil casing. The main factors of gray spots welds welded base metal chemical composition, welding temperature, the welding speed, the pressing amount, as well as the opening angle before welding strip edge shape and surface quality. Strict quality control strip edge and welding process is the main way to solve the weld gray spots Slitting unit price, by pre-weld heat treatment and hot stretch reducing whole tube heating oil can reduce the weld seam sleeve gray spots appear trend. 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. What Taiyuan Huaxin Cheng electromechanical you resolve critical aspect is the spiral welded pipe mill spiral welded steel pipe spiral welded pipe mill is mainly used to transport oil and natural gas producer slitting machine can be used to transport water, gas, steam and other pressure pipelines widely used in petrochemical, heat pipes, and other engineering structures, spiral welded pipe mill can curl into a cylindrical spiral steel pipe, welded by automatic welding equipment, calculated according to the molding strip width, thickness and diameter for adjusting the position of the crane corner of the plate roll forming rolls placed on the volume small car, uncoiling trolley on wheels, the largest of its rigid structure can carry 35 tons, the driver will be transported by the motor coil to uncoiling rack.
