The production lines are used to
make plastic-aluminum-plastic (PAP) multilayer pipes.
The external and internal layers of the pipes are plastics, e.g. PE, and middle
layer is a butt-welded aluminum. All the layers are solidly adhered with each
other, therefore, the pipes are also called composite pipes or composite
The pipes made by these lines are in compliance with ASTM-1335-2004 .
v High yield speed, up to 20m /min,
v High operating reliability, yielding high quality pipes continuously,
v Low power consumption, only 160KW total actual power consumption of a line,
v Fast exchanging welding guns without interrupting pipes yielding with a
v Precision aluminum pipe forming system based on know-how,
v Precision butt-welding system, great welded seam strength and excellent
roundness of the yielded pipes,
v High performance extruders with precision dies and advanced vacuum
v Remote network control system based on PLC control, special control software,
v Can be extended to produce composite stainless steel-plastic pipes.
