Non-Linear Slotting Profiles for Pipe and Pipe Liners

A method of forming non-linear slots in pipe and the resulting slotted pipes are disclosed. The non-linear slots can be created using fluid jet, plasma, laser or any cutting method capable of producing a non-linear slot through the wall of a pipe. One embodiment includes interruptions in the slots t...

Zusammenfassung:	A method of forming non-linear slots in pipe and the resulting slotted pipes are disclosed. The non-linear slots can be created using fluid jet, plasma, laser or any cutting method capable of producing a non-linear slot through the wall of a pipe. One embodiment includes interruptions in the slots to form ribs or structural connections between the pipe material along either side of a slot. The non-linear slots can be arranged in longitudinal, latitudinal, or in a helical orientation around the axis of the liner in straight, staggered, or ganged patterns. The slots can be formed in any non-linear shape, pattern, or slot thickness. One method employs high pressure fluid jet cutting from within the pipe, resulting in slots having a smaller width at the outside surface of the pipe.
