摘要： PROBLEM TO BE SOLVED: To provide improved pressure cast lined steel pipes.SOLUTION: 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.
