The extrusion line for PE Double
Wall Corrugated Pipe is a new research achievement in Zhongyun in the plastic
extrusion field. The production of the pipe by direct extrusion is highly
efficient and reliable. Because of the excellent design of wall construction,
the pipe can ensure the lightest weight in comparison with other constructions.
This means the cost of the pipe can be decreased greatly and the pipe''''''''s
competitive ability can be increased. It is widely used both at home and abroad
as it is an easy and reliable coupling without any complex fitting, and replaces
the concrete pipe and cast iron pipe. In China, PE double wall corrugated piping
is being used extensively to ensure the development of environmental protection
during networking of water and sewerage..
? It adopts efficient screw and notched barrel, the inner and outer walls are
separately extruded by two extruders for using different materials and ensuring
? A high speed of production can be ensured by the corrugated forming system and
forced cooling system combined with water and air cooling during constant
production.The advanced programmable lubricating system decreases abrasion of
mould blocks to a minimum while lengthening their lifespan and ensuring running
precision and stable quality.
