Double Wall Corrugated HDPE Pipe Lines

We started to successfully make this kind of machine in 1999, to be the 1st Chinese company in this field. We have both SN4 and SN8 systems.

Well designed BM screws are applied to the line, which give the line hi-efficient and good quality plasticating, stable pressure of melt flows, can greatly improve extruders' capacity and stabilities.

Following the main international trends, Main extruder gear box is of hi-torque gear box, equipped with trust base; All well selected materials are professional treated and made, thus it runs stably and with low noise.

Our spiral flow channels dies are of low resistance, making melt flows goes evenly, materials' thickness can be regulated in a certain ranges. Hi-temperature resistant steel alloys are used and specially treated, its fatigue strength limit is quite high, it can stand lashing test for many times, low temperature lashing toughness is fine. Thus our dies are durable.

Corrugator is the key of the line, ours is vertical, well constructed. Our forming blocks, mould base plate, rail, wall and other components are precisely made, to ensure forming blocks can accurately counterpoint in the forming path. After forming, blocks release vertically in ladder like way, which can make sure, at the best, that pipes can be moved smoothly and pipes keep bright and clean, excellent pipe waves.
