Double-Pipe Extruding Production Line The production line is developed with the 1990s advanced technology of west Europe by our company. The main machine is SJSZ 55/10 or SJSZ65/132 conical twin-screw extruder, is equipped with double tube single-control stainless steel spraying shaper to form a production line. It avoids a waste condition when one tube is adjusted and the other one is affected...The auto single-control double haul offs and cutting are combined with the front shaping technology to make operation more flexible. Let you enjoy econo-mic benefit which is brought about by separately control double-tube extruding. The diameter of the extruded pipe is from *20-*63. It can make fully use of the extruding capacity of the extruder. Even if it produces small diameter pipe. It can get great output too. Max output of extruder (kg/h)150-250Vacum tank length (m)3-4Haul-off speed (m/min)0-15Max diameter of twin pipe(mm)Φ63Haul-off force(N)1000Drive motor power(kw )4*2
