| Introduction:The extrusion line is mainly for producing large diameter hollow wall winding pipe. Large diameter winding pipe (inner diameter from 150mm-2200mm) has high ring stiffness and high brunt intensity with structure. It can be used for approximate 50 years and has many advantages such as low cost assembly and easy operation, withstand ing pressure, corrosion resistant such as acid, alkali and salt etc, It is becoming as a replacement of cement pipe and cast iron pipe. nowadays, It is being widely used as sewerage and drainage pipe.Production line features:The extrusion line is designed with advantaged technology.High speed and excellent extrusion quality by adopting two sets of single screw extruder with high efficiency performance.Unique design of composite die-dead for large diameter winding pipe processing with high production efficiency. High quality of winding pipe produced by adopting the unique winding process. Easy operation and high performance by adopting an advanced PLC control system with touch sereen. |
