it can be used with/without the pipe extruding machine. During pipe expanding, the pipes are moved horizontally, thus the action is stable and correct without damaging the pipes. This machine adopts IR heating mode and double heating furnaces; the pipe forming dimension is correct. Without switch of solvent-expanding socket (straight) or flexibility-expanding seal ring socket (R), the selection of pipe expanding mode is quite convenient and the technique adaptability is quite good. The control components of the main electrical appliances are imported and the system performance is stable and reliable.
