A metal -plastic pipe consists of a three -layer structure: a pipe (main part) made of stitched polyethylene, a shell from polyethylene protection and a layer of aluminum foil. The foil has a thickness of 0.2 to 0.5 mm, and the protective shell guarantees high mechanical strength and a high level of resistance to internal pressure. The metal -plastic pipe is good for use, as it is easy to install, and also allows a bend without a spring, the radius of which can be up to five diameters.
