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 spiral welded pipe mill for you to share relevant knowledge diameter spiral welded steel pipe unit has a hollow cross section, a large number of pipelines for transporting fluids corrugated pipe equipment, such as the transportation of oil, gas, gas, water and some solid materials and so on. Such as steel and solid steel bar, compared with the same torsional strength pipe bending equipment manufacturers, lighter, an economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as drill pipe, automotive transmission, bicycle frames and construction using steel scaffolding. Thermal expansion of steel is an important raw material of industrial construction, aerospace, geology, oil refining, machinery and other industrial equipment necessary foundation. Spiral welded pipe mill capable of producing thermal expansion pipe, marking the transition on the road to industrial countries has taken a solid step forward. To 6% annual growth increments, galvanized as a relatively inexpensive pipe corrosion protection equipment, construction industry corrosion protection plays an important role. Thermal expansion of galvanized steel in the actual corrosion can play an important role in achieving good use value trends, in accordance with the standards and form. In general, the diameter of the tube can be divided into outer diameter, inner diameter, nominal diameter Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. is specialized in the design, development and manufacture of welded pipe equipment, spiral welded pipe equipment, cold-formed steel equipment, sheet and tube finishing equipment and high-precision slitting line equipment, high-tech enterprises. Taiyuan Huaxin Cheng electromechanical equipment to introduce you to the high-frequency welded steel pipe advantage of high-frequency welding process, mainly on the use of high-frequency currents have skin effect and proximity effect two properties so that the current highly concentrated in the surface of the weld edge pipe equipment quotes, tube welding edge in a very short period of time is heated to the desired temperature soldering, and then after squeezing a tube welded tube synthesis. High frequency welding technology has many advantages, for tube and pipe sizes of materials wide adaptability. Not only high-frequency welding welding speed increase and get a small heat-affected zone and burn through good weld. Because of the high frequency weld pipe with good quality, both inside and outside a small glitch, high welding speed, lower power dissipation, etc., has been widely used and promoted. Macau welded pipe equipment manufacturers _ _ Huaxin Cheng electromechanical equipment provided by the Electrical and Mechanical Equipment Co., Ltd., Taiyuan Huaxin Cheng. Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. (www.tyhxc.com) strong, credible, and other industries in other Jinzhong accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Huaxin Cheng electromechanical and you hand into the brilliant, for a better future!
