Pressure cast lined steel pipes comprise an annular concrete or mortar liner (14) along an inside diameter, and a metal shell (12) surrounding the liner, wherein the liner (14) is in direct contact with the metal shell (12). The wall thickness of the liner can be from 10 to 50 times the thickness of the metal shell The pipe may be coated with a dielectric material A mold assembly used to form the pipe includes an annular concrete or mortar composition chamber formed between the metal shell and an inner mold member Pressurized water is used in the mold assembly to pressurize the concrete or mortar composition and exert a desired pressure force onto the metal shell while the composition cures in the mold Once a desired degree of cure is achieved, the pressure is removed causing the metal shell to exert a desired compression force onto the cured liner
