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 galvanized pipe to introduce you to the role and preparation work there except caustic acid, both of which remove stains, but for slightly different stains! Pickling The purpose is to remove the steel surface oxide skin! Then follow strict plated pipe equipment before operating, but also the advantages of using hydrochloric acid is that it can operate at room temperature, the ability to remove the oxide scale is strong, the base metal less affected by erosion, absorb less hydrogen, carbon black residue The possibility of contamination of small, iron oxides produced pickling slitting equipment, deep angle, easy to remove, no effect on the galvanized, galvanized from the perspective of how much money slitting equipment, hydrochloric acid is relatively Suitable. However, the low price of sulfuric acid, easy regeneration, so pickling solution countries to choose depending on the circumstances, the United States more than slitting equipment manufacturers with sulfuric acid, hydrochloric acid and multi West Germany. 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 to introduce you to the high-frequency welded pipe production process through the use of high-frequency welded to a steel roll forming alternating skin effect and proximity effect, to form a circular cross-section of the tube is disconnected, close the center of rotation within 1 or a group of the induction coil pipe resistance, is formed have an impact on the skin effect and the proximity effect of the electromagnetic induction coil impedance tube opening, the opening of the tube edges to produce a strong and thermal effects concentrated , the edge of the weld is rapidly heated to a desired temperature pressure welding after extrusion by the roller when the metal in a molten state to achieve indirect crystals together, after cooling to form a strong butt weld. Slitting equipment, slitting equipment, electromechanical provided by Huaxin Cheng Electrical Equipment Co., Taiyuan Huaxin Cheng. Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. (www.tyhxc.com) (www.tyhxc.net) strong, credible, and other industries in other Jinzhong accumulated a large number of loyal customers.
