Abstract: A handling assembly includes motor driver wheel assemblies that are supported on one or more platforms. The wheel assembles can be moved inwardly into engagement with tubing, cable or rods extending through the platforms so that the tubing, cable or rods can be raised or lowered in a controlled manner by frictional contact between the driven wheels and the tubing, cable or rods.

Abstract: A material separator removes material such as sand from a fluid utilizing an inclined housing having a fluid flow inlet in a lower portion of the housing. Higher density material descends by gravity to a lower wall of the inclined housing and continues to travel down the lower wall portion to a lower section of the housing where it is removed. The remaining fluid which may contain a liquid and a gas is removed from the housing via an outlet at the upper portion of the housing.

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.
