1.The production line is developed with the 1990s advanced technology of West Europe by our company. 2.The main machine is SJZ51/105 or SJZ65/132 cone double-screw-stem Extruder, is equipped with double-tube single-control stainless steel spraying shaper to form a production line. 3. It avoids a waste condition when one tube is adjusted and the other one is affected. The auto single-control double drawing machine and cutting are combined with the front shaping technology to make operation more flexible. Let you enjoy economic benefit which is brought about by separately control double-tube extruding. 4.The diameter of the extruded pipe is from 20-50mm. It can fully use the extruding capacity of the extruder. Even if it produces small diameter pipe, it can get great output, too. Main Technical Parameter: Max output of extruder(kg/h) 150-250 Vacuum tank Length(m) 6 Traction speed(m/min) 0-15 Max diameter of twin pipe(mm) 63 Traction force(N) 2000 Drive motor power(KW) 4x2 pvc twin pipe production line/pvc double pipe production line
