Hot Rolling Seamless Pipe Production Line

 

There are three basic processes for hot rolling seamless pipe production line :

â‘ Punch the ingot or billet into a hollow thick-walled rough pipe on the piercing machine.

â‘¡Stretch the rough pipe to form a rough tube close to the wall thickness of the finished product.

â‘¢Roll it into the required finished tube on the finishing mill.

 

MAφ159mm~φ325mm hot rolling seamless pipe production line which produce the seamless steel tube /seamless pipe. The main equipment includes billet band saw and conveyor units, rotary furnace (16m pitch diameter) (self-prepared by user),two conic-rolls hot piercing mill (horizontal type), Accu-Roll restraining mandrel elongator (with mandrel cooling cycling device), high-pressure descaling device(self-prepared by user), sizing mill (12-stand, φ600mm ), chain-type cooling bed, 6-roll tube straightener, finished pipe band saw and R-part profiling machine for sizing stands (self-prepared by user).
