The invention relates to a machine for coating the interior of a pipe. The machine can be pulled through and positioned within a pipe or pipeline by a internal pipe tractor, and can be used to apply viscous liquids, including two part epoxies and urethanes, to the interior wall of the pipe. The machine is typically used for the overcoating of portions of pipe having defects in their internal coatings, for example, at their girth welds.

Internal girth weld liquid coating cart

A process for the production of extra fine spherical metal powders by chemical vapor deposition and dissolution techniques, including metal carbonyls, wherein the metal containing process gas is propelled upwardly through a heated reactor. By employing an upward gas flow as opposed to the conventional downward gas flow, a closer approximation of theoretical plug-flow velocity profiles are achieved thusly resulting in a desirably narrower size particle distribution obviating or reducing the need for subsequent classification techniques.

Process for producing metal powders

A continuous method of manufacturing a liquid dispersion containing submicron metal or metal compound particles inside a liquid bath. A metal-containing fluid with carrier gas mixture is bubbled through the liquid bath and predetermined conditions in the bath cause the fluid to decompose to form the submicron sized metal or metal compound particles in the liquid.
