BONDING OF STEEL STRIPS IN STEEL STRIP LAMINATE PIPE

摘要

A steel strip laminate pipe having increased lap shear strength and peel off strength between the steel layers (44, 48, 52) in the pipe and a method for making such a steel strip pipe are provided. Steel strips (44, 48, 52) coate d with a sol-gel or a silane adhesion promoter are wound over an inner lining (40) to form steel layers bonded to each other in a steel strip laminate pip e. In an alternate embodiment, fiber fillers (46, 50) and resin are used to bon d the steel layers in the pipe together. In a further embodiment, glass sphere and resin are used to bond the steel layers together. The steel strips bonde d 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 .
