System for maintaining conduits and pipes in a pipeline system
A system for maintaining conduits and pipes after their installation into a pipeline system used to transport material in a fluid or flowable form. The system includes a maintenance tool adopted for use inside the pipe, an umbilical attached to the maintenance tool for pulling the tool through the pipe; and a pluralities of bearings positioned around the umbilical in order to allow the tool to be pulled through the pipe around bends and turns in the pipe.
1. A system for negating friction and seizure of umbilical supply lines attachable to a tool inside a pipe, said system comprising:
a plurality of spaced apart annular disk assemblies, each annular disk assemble comprising an umbilical aperture and a plurality of angularly spaced rollers mounted generally on, and extending radially therefrom, an outer circumference of said annular disk assembly;
a plurality of flexible chain link sections, each chain link section comprising a plurality of interconnected links and having a maximum length when said links are fully extended and a minimum length when said links are fully retracted;
wherein said plurality of spaced apart annular disk assemblies are arranged along the length of said umbilical supply lines with said umbilical supply lines passing through said umbilical aperture and wherein each of said annular disk assemblies is coupled to immediately adjacent said annular disk assemblies by a plurality of radially spaced said flexible chain link sections;
wherein said system surrounds said umbilical supply lines and maintains an orientation of said plurality of rollers to contact inside surfaces of said pipe as it moves through said pipe.
2. The system of claim 1 , wherein said system is adapted for being rolled onto a take-up reel as said system is retracted from said pipe.
3. The system of claim 1 , wherein said system is configured to be connected to a control unit, wherein said control unit comprises a central processing unit and operating control software.
