  • Sludge pipeline lubrication system
    Patent number: 5479957
    Abstract: A system for lubricating a plug flow of high viscosity material in a pipeline is disclosed. The system includes first and second pipes through which the plug flow of high viscosity material is pumped. The first pipe has a flange which is positioned adjacent a flange of the second pipe. A plurality of bolts, attached to the flange of the first pipe and to the flange of the second pipe, connect the first pipe to the second pipe. A lubrication spool is positionable in a first location between the flange of the first pipe and the flange of the second pipe for lubricating the plug flow of high viscosity material. The lubrication spool is removable from the first position without completely disconnecting the first and second pipes. The lubrication spool includes a first spool section which is located immediately adjacent the flange of the first pipe while in the first position and a second spool section immediately adjacent the first spool section.
