摘要： Pressure cast lined steel pipes comprise an annular concrete or mortar liner along an inside diameter, and a metal shell surrounding the liner, wherein the liner is in direct contact with the metal shell. 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.

摘要： A steel strip laminate pipe having increased lap shear strength and peel off strength between the steel layers in the pipe and a method for making such a steel strip pipe are provided. Steel strips coated with a sol-gel or a silane adhesion promoter are wound over an inner lining to form steel layers bonded to each other in a steel strip laminate pipe. In an alternate embodiment, fiber fillers and resin are used to bond the steel layers in the pipe together. In further embodiment, glass sphere and resin are used to bond the steel layers together. The steel strips bonded together using continuous reinforced fiber filler or glass spheres may be coated with sol-gel or silane. In an alternate embodiment, the sol-gel or silane may also be mixed in the resin used to bond the steel layers together.

摘要： Mortar-coated steel pipe comprise a steel cylinder having a mortar layer disposed therein, such mortar layer being free of any metallic reinforcement. An overcoat is disposed over the mortar layer and is formed from a material that is a dielectric and/or a barrier to moisture and oxygen entering the mortar layer, e.g., a polymeric material. The pipe may include a further concrete or mortar layer disposed over the overcoat, forming an outermost pipe surface. The outer layer can be cement, mortar, or other material. The mortar layer thickness is about 2 to 30 mm, the overcoat thickness is about 0.1 to 2 mm, and any outer layer thickness is about 1.2 to 4 cm. The pipe is made by compression coating method, where mortar layer and overcoat are applied simultaneously. When an outer layer is desired, it is preferably applied at the same time as the mortar layer and overcoat.
