Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. is a high-tech enterprise specialized in the design, development and manufacture of equipment Longitudinal spiral welded pipe equipment, cold-formed steel equipment, sheet and pipe finishing equipment and high-precision slitting line equipment. Taiyuan Huaxin Cheng electromechanical equipment you elaborate pipe sizing method to the inner pipe equipment sizing head Expanding the outer peripheral surface of the weld zone is non-sizing pipe wall in close contact, and at this time sizing head outside As a reference diameter sizing sizing head by setting quantitative expansion expansion open, for a given diameter pipe segment is applied to the inner wall of the radial force, so that the wall is plastically deformed radially retracted sizing head spiral welded pipe equipment, quality assurance, given Trail head toward the next adjacent pipe sections until the desired pipe sizing is completed. No cutting process, is a method of pipe sizing device. Pipe from the inside to the feeding tube apparatus Expanding sizing head, and then start the first cylinder, so sizing mandrel head within the mobile device of choice for spiral welded pipe, the sizing stretching apart and the inner wall of the pipe weld area non- in close contact, and the outer diameter of the head at this time sizing sizing as a reference. Then start the second cylinder, so that by the amount of sizing head expansion set to continue expansion of open radial force is applied to the pipe, so that the pipe is plastically deformed. Finally sizing head retraction is completed. Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. is a high-tech enterprise specialized in the design, development and manufacture of equipment Longitudinal 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 explain spiral welded pipe equipment pipe equipment due to the size and needs of each plant is different, so many species, and spiral welded pipe equipment in many other categories in its complex production process and strict requirements for the material to be called pipe equipment industry, "porcelain doll." A spiral welded pipe equipment production after at least 13 steps, interlocking, any step astray is likely to produce defective even cause damage to the machine, so the operator is also high. Spiral welded pipe using a strip coil as a raw material spiral welded pipe equipment factory direct, first to go through the normal temperature extrusion, after forming, welding processes must use the automatic double-wire submerged two-sided, and finally into a spiral pipe joints. If the machine according to the different ways of feed can also be divided on the roll, the next roll, the roll of both types are generally used only on special occasions, relatively lower volume formula is more commonly used. In addition to feeding mode according to points, according to the molding methods can also distinguish between the bed and scroll down molding machines. Which is better _ spiral welded pipe Huaxin Cheng electromechanical equipment (certified) _ spiral welded pipe equipment from Taiyuan Huaxin Cheng Electrical Equipment Co., Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. (www.tyhxc.com) (www.tyhxc.net) is Jinzhong, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum to meet customer needs.
