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 for you to resolve key issues Longitudinal Shanxi Shanxi unit production toughness Longitudinal unit production tubing and casing, due to the toughness of the weld affected base metal toughness, chemical composition of the base metal and welding processes. When the reduction in raw material strip in C, S, P, Cr element content, etc., can be improved weld toughness; when controlling the welding 程中亮 line width, angle and streamline the welding process, also non-metallic inclusion content can significantly improve the toughness of the weld; stainless steel welded pipe mill in addition, by controlling the cooling heat pipe reducing tension after welding can improve oil casing pipe welds and other areas of strength and toughness. 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., welded pipe mill manufacturers to introduce you to tell your pipe unit composition and use of professional pipe machine has several parameters compared Longitudinal units, steel pipe welding machines, welding steel pipe means or bending the steel sheet is circular, square, etc. into shape after the welding pipe unit, the surface of the steel pipe joints, as well as high-frequency straight seam resistance welding. Welded steel pipe: welded steel pipe refers to a steel strip or plate bending circular, square, etc. in shape after welded into the surface jointed pipe. Casing: depth from the ground surface within the drilling pipe unit manufacturers, as the wall of the liner pipe through the coupling connection between its tubes. The main material for the J55, N80, Q125 and other steel grades, as well as anti-hydrogen sulfide corrosion C90, T95 and other steel grade. Welded pipe mill plant, Huaxin Cheng electromechanical (certified), Roraima pipe unit provided by the Electrical and Mechanical Equipment Co., Ltd., Taiyuan Huaxin Cheng.
