High Frequency Welded Pipe Mill: Feed steel pipe of a certain specification into the machine and then use forming roll to crimp the steel strip into pipe-blank.  Under skin effect and proximity effect of high frequency electric current, induced electricity is concentrated onto the bonding surface of the pipe profile fringe and heat up the pipe profile fringe quickly to the welding temperature and finish welding under the pressure of the squeeze roller. After cooling, sizing and broad straightening, you can get the steel pipe of needed specification. Our products such as roll forming unit, FFX forming unit, cage forming unit of X80 and X100, J55 API petroleum casing pipe and petroleum and gas pipe, conform to the standard of API-5L，API-5CT.

Directly Molding Side Welded Pipe Mill: The equipment adopts modular mold, more prebending and directly molding side craftwork, which has the characteristics of no tearing down the main shaft, no tearing down stander, changing roller quickly and low loading. It can reduce 60% of die roll cost and the time of changing roller. The four angles of the square and rectangular pipe have the same thickness and high strength. It is suitable for small production but different specification.

Carbon Tube— Stainless Steel Composite Pipe Mill: Forming through mold, it is welded by duplex metal such as stainless steel and excellent carbon construction steel. This 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.
