LARGE DIAM，HDPE PIPE EXTRUSION LINE LARGE CALIBRE HDPE BURIED WATER-SUPPLY PIPE PRODUCTION LINE Because of its advantage in aspects of the environmental protection(poison-less),installation and construction ,large caliber HDPE supply pipe is the first choice for the outdoor service pipes,People lay greater important on them in the old pipe repair and urban water supply systems; This production line adopts the efficient single-screw extruders with specially designed shielded type Bmscews in order to ensure the thorough meltiog of the matter,thus vigorously enhances the extruxion volume. The die adapter utillzes the lately designed basket type nose or the spiral divided hand-piece,it may produce the double-ply anti-ageing environmental protection model buried water-supply pipelines; Planet cutting,section smoothing,chamfered standardization,dust-collecting device may fulfill the non-scraps cutting. LARGE CALIBRE HDPE/MDPE GAS PIPE PRODUCTION LINE HDPE/MDPE gas pipes manufactured by this production line become the first-choice products in the urban gas conveying pipelines because of their moderate rigidth;sound flexibility,and ticreeping performance;ambient stress tear resistance;wonderful thermo-welding performance;Each production line has two extruders.The major one employs the brute force converyance bushing and the effective screws.The smaller one is used for the extrusion marker lines;The nose adopts the lately-designed basket type hand-piece or the spiral shunt type extruding pipe composite nose.It has characteristics such as easy adjust and even discharge.The sizing sleeve utilizes the unique slitting craft and liquid ring cooling in order to guarantee the accuracy of the pipe forming.
