Carbon Tube— Stainless Steel Composite Pipe Unit adopts the advanced synchronous welding combination method. Along with carbon steel pipe welding production line, Synchronous welding combination method covers the surface of the carbon steel pipe with stainless steel cold belt synchronously. Through welding, sizing, straightening, length-fixing and polishing, the final pipe is produced. The products have high accuracy, firm package and good performance of deep manufacture and possess the intensity of the steel pipe and the beauty of the stainless steel pipe. It is mainly used into textile machinery, food machinery, decorating, carriages and poles in the municipal construction, etc. As new, green and energy-saving material, stainless steel composite pipe has been used in the main national project in the past few years.
