Based on 20 years of experience in the development and design of plastic machinery, Qingdao BEST company absorbing the advanced technology has developed the new type of HDPE water/gas pipe line. The series of pipe production line adopts High Efficiency & Energy-saving Single Screw Extruder and Gravity Metering unit of Germany INOEX Brand, it can effectively control the pipe thickness, improve the rate of finished products, save the material and industry electric cost, improve productivity and engery-saveing.

HDPE Large Diameter Gas and Water Pipe produced by this line has the features of the excellent stiffness,flexibility,heat resistance, aging resistance, high mechanical strength, resistance of enviromnental stress cracks,resistance to creep deformation, corrosion Resistance and heat-linkage, and so on,So,it is a preferred gas and water pipe for ductwork system between city and its suburb,large diameter HDPE pipes start to play a very important role in the city water an gas supply systems.

The series of HDPE pipe production line can produce the two layers, three layers and multi-layers composite pipe or reinforced composite pipe after the line is be updated by changing the pipe mould and increasing the quantity of single screw extruders.
