In recent years, the large-diameter pipe extrusion line, especially in the large-diameter multi-layers composite pipe extrusion equipment is the weakness design in domestic plastic extrusion market, lower capacity, high energy consumption, low automationcontrol system and accuracy, complex operation the main case was the perfect pipe in low and not bring high profit for all customers,At the same time ,the energy saving policy discrepancy.Thus, the NEW market required low-power, high-capacity, high precisioncontrolled, easy to operation, intelligent controlled of the large diameter multi-layerscomposite polyethylene pipe extrusion line tothe domestic demand for pipe supplier Plant urgently.

In view of the above circumstances, BEIER Machinery organized R & D personnel conducted an investigation both of the national and international markets, to learn the international advanced extrusion on the basis of further innovation and integration advantages of national products, incorporated with the design and development of scientific and technical for many years experience, successfully developed large caliber intelligent multi-layer polyethylene pipe production line. And access: invention patent (No. 2012101859352), utility model patents 7 (No.:2010205699768,2011202026737,

2010205719193,2010205699908,2011202026845,2010205699698、2010205699630).

All the completed extrusion line controlledby PLC, Worker to Machine interface dialogue, to achieved the main extruder ,co-extruder, and haul off in synchronous speed, thus, the operation is extremely simple design. For example, as long as the pipe weight per meter input PLC panel, then transferred to the main extruder to desired speeddirectly, and the co-extruder and haul off will appropriated the speed up to the requirements of gravimetric meter automatically This operation extremely simple as true called "stupid machine." Truly large-diameter polyethylene pipe multilayer intelligent control.

This extrusion line was tested by theTesting Center of Jiangsu Prov.China , All seized indicators in the extrusion line with corporate standards (Without industry standards or national standards in China) requirements specified Q / 320582BRJ16-2015; the novelty search organization by national level - Science Technology Advisory inquiry Center,Jiangsu ,No found same extrusion design in the Chinese market.

This extrusion line was approved by the identification of new products of Machinery Industry Association of Jiangsu Provinceon 4th.Dec, 2015 , All identified experts unanimously agreed the new extrusion design is the leading national level in China.
