Technical Structure Rifeng pipe is five-layer composite pipe that combines the advantages of a metal and plastic pipe and eliminates the disadvantages of both materials at the same time. The aluminum core is absolutely diffusion tight; it reliably prevents oxygen/gases from permeating into pipe. It compensates and reduces snap-back forces and heat expansion with changes of temperature.
Overlapped welded pipe is co-extrued with one step with perfect adhesive between inner layer and aluminum, high and stable pressure resistance, of which welding style is ultrasonic.
Butt welded pipe is moulding with several steps that is argon-arc welding style.
Note:The color of Rifeng pipe is optional.
