A composite pipe which is replaced with a carbon steel pipe and air conditioner copper pipe for the general pressurizing pipe prevents the scale occurrence inside the copper pipe since the inside fluid velocity is fast. A composite pipe which is replaced with a carbon steel pipe and air conditioner copper pipe for the general pressurizing pipe comprises a first resin layer(1) which is placed at the deepest position of the pipe, a first bonding layer(2) sharing and uniting both the radical base of the first resin layer and radical base of a metal layer(3), a metal layer sharing radical bases of metal respectively, a second bonding layer(4) sharing and uniting both the radical base of the metal layer and a radical base of a second resin layer(5), and a second resin layer which is placed in the outermost of the pipe and applies the resin, and then gives polarity. |
