Automatic Saddle Welding

Saddle welding procedure requires the use of a Saddle Fusion tool. This tool must be capable of holding and supporting the pipe, rounding the pipe for proper alignment between the pipe and fitting, holding the fitting, and applying and indicating the proper force during the heat fusion jointing process. The heating and fusing process must be performed with accuracy and efficiency, especially when fusing to a pressurized main pipe. Automatic saddle welding machines with CNC control system promise operator to follow the welding temperature, welding time and jointing pressure after choosing welding standard, pipe size and material. CNC HDPE reducing tee saddle fusion welding machine, which is produced under a high technology with special design of pipe fusion machines, has the principle of working on the logic of the hydraulic system. For high quality reducer and high accuracy and working efficiency, Wuxi Yuda MRH-A Automatic HDPE Fitting Reduing Tee Saddle Fusion Equipment is your best choose.
