Does the production process of aluminum-plastic composite pipe determine the thickness of the aluminum strip?
As we know, one of the key raw materials of the aluminum-plastic composite pipe is the aluminum strip, and the thickness of the aluminum strip directly affects the performance of the aluminum-plastic composite pipe.
However, whether the production technology is advanced or not directly limits the diameter of the aluminum-plastic composite pipe, and also affects the range of the thickness of the aluminium strip.

2 production processes of aluminum-plastic composite pipe
1. At present, the most common production process is the overlap structure method, that is, the lap-welded longitudinal aluminum tube is made first, and then the inner and outer plastic tubes are made on the formed aluminum tube. The diameter of the finished pipe is generally less than 32 mm, and the thickness of the aluminum layer is 0.2-0.3 mm;

2. Another more advanced processing technology: the butt joint method, that is, to make the inner plastic tube first, then make the butt-welded aluminum tube on it, and finally cover the outer layer with a plastic layer. The diameter of the finished pipe can reach 75mm, and the thickness of the aluminum layer is 0.2-2.0mm.
