The production line is developed with the 1990s advanced technology of Western Europe by our company.The main machine is SJZ51/105 or SJZ65/132 conical twin-screw extruder,is equipped with double-pipe single-control stainless steel spraying & calibration tank.It avoids a waste phenomena when one pipe is adjusted and the other one is affected .The auto single-controldouble haul-off and cutter are combined with the front calibration technology to make operation more flexible.Let you enjoy economic benefit which is brought about by separately control double-pipe extruding . The diameter of the extruded pipe is from Φ16-Φ63.It can fully make use of extrusion capacity of the extruder.Even if it production small diameter pipes,it can get very high output , too.
