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. Founded 10 years ago, with strong technical strength, the unique core technology in the field of design and manufacture of pipe equipment has won a high reputation. In recent years, "Hua Xincheng" There are hundreds of sets of sets of units on the market flat head machine supply, product convergence cover nearly 20 domestic provinces and cities and exported to Canada, Egypt, Israel, Turkey, Indonesia, India, Vietnam, more than 20 countries. Taiyuan Huaxin Cheng electromechanical equipment spiral welded ask you introduce a common defect that how to detect? Spiral welded pipe equipment common drawback magnetic particle testing or penetration testing. Spiral welded pipe equipment can detect magnetic particle testing or soaked appearance of cracks found useful, folding, heavy leather, hairline, pinhole appearance shortcomings. About ferromagnetic materials, magnetic particle inspection method should be preferred, because of its high detection sensitivity; on non-ferromagnetic materials, such as stainless steel spiral pipe, the selection soaked detection. 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 spiral welded pipe equipment production process more stringent spiral welded pipe end machining equipment so that the end vertical slope altercation and accurate control of the blunt edge, characteristic spiral steel pipe welded pipe production process is simple, productivity high costs and flat-head machine, faster development. Strength of spiral welded pipe mill is generally higher than the Longitudinal, how much money can narrow the billet production of large diameter pipe flat head machine, you can use the same width of the billet production of different pipe diameters. However, compared with the same length of straight pipe seam weld length of 30 to 100%, and lower production rate. Therefore, most of the more *** of a straight seam welded pipe, large diameter spiral welded pipe for the most. Weld gap control device to ensure that the weld gap to meet the requirements of the procurement flat welding machine, diameter, volume and the wrong side of the weld gap have been strictly controlled. After welding the weld line, continuous ultrasonic injury checked to ensure 100% coverage of non-destructive testing spiral weld. Purchase flat head machine, Huaxin Cheng electromechanical (certified), Malaysia flathead machine provided by the Electrical and Mechanical Equipment Co., Ltd., Taiyuan Huaxin Cheng. Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. (www.tyhxc.com) is Jinzhong, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
