A multilayer composite pipe structure is described. The multilayer composite pipe comprises a hollow inner conduit, a first layer of adhesive, a metallic intermediate layer, a second layer of adhesive, as well as, the outer thermoplastic layer, respectively. The hollow inner conduit is made from any rigid thermoplastic material. The outer thermoplastic layer is made from a rigid, amorphous thermoplastic polymer. This multilayer composite pipe is pressure bearing. In one embodiment, the multilayer composite pipe is solvent cementable; whereas in another embodiment, the multilayer composite pipe is heat fusible. In still yet another embodiment of the invention, the multilayer composite pipe is bendable. Furthermore, the multilayer composite pipe can be used in a fluid conduit system with fittings with an optional insert.
