Abstract: The invention is directed to an apparatus, or system, for applying a multi-component liquid liner composition to an inner surface of a conduit. The system comprises a first reservoir having a first liquid liner component; a second reservoir having a second liquid liner component, the second liquid liner component being different from the first liquid liner component; a first liquid liner component transmission line in communication with the first reservoir; a second liquid liner component transmission line in communication with the second reservoir; and an applicator in communication with the first and second liquid liner component transmission lines. Methods of applying multi-component liquid liner compositions to the inner surface of conduits are also disclosed.

Abstract: A fluid jetting nozzle includes a nozzle head and at least one jetting orifice in the nozzle head, the jetting orifice(s) being capable of ejecting a mixture that includes substantially spherically shaped solid particles and fluid to loosen obstructive material from a metallic surface.

Abstract: A system capable of removing scale deposits from an interior metallic surface of a conduit includes a mixture including a plurality of substantially spherically shaped solid particles and fluid, a mixture delivery tubing insertable into the conduit, and a nozzle attached to the mixture delivery tubing. The nozzle includes a plurality of nozzle jets and is capable of ejecting the mixture to loosen scale deposits from the interior metallic surface of the conduit.
