A lube skid apparatus configured to be moveable and transportable. The lube skid having one or more tanks carried by a scaffold of the lube skid. One or both tanks having sloped bottom walls to optimize flow of fluids in the tanks to minimize residual fluid left in the tank. One or both tanks having sloped top walls configured to contain and direct the flow of fluid spills on the skid to an adjacent sump. The skid also carries a plurality of service devices such as a motor, an air compressor, a tank to hold compressed air, pumps to move fluid with associated filters and hoses, and one or more service storage drawers.

A self-cleaning conduit for a hydrocarbon fluid. The conduit includes a tube having an interior surface defining a flow passage for the hydrocarbon fluid. The tube is formed of (i) a shape memory alloy or (ii) a first metal and a second metal having a coefficient of thermal expansion different from the first metal. At least one of a plurality of recesses and a plurality of protrusions are formed on the interior surface of the tube within the flow passage. The tube is characterized by a conduit contortion factor (CCF) from two tenths degrees Fahrenheit (0.2? F.) to fourteen degrees Fahrenheit (14? F.), and the conduit contortion factor (CCF) is one of an elastic conduit contortion factor (CCF.sub.E) and thermal expansion conduit contortion factor (CCF.sub.TE).
