US Patent:

42494753, Feb 10, 1981

Filed:

Oct 10, 1978

Appl. No.:

5/950246

Inventors:

David L. Lindsey - Houston TX

Assignee:

Mustang Services Company - Houston TX

International Classification:

B05C 708

US Classification:

118105

Abstract:

Apparatus for treating the internal wall of a pipeline by scraping, cleaning, painting or the like, including an elongated pig, a mounting assembly connected to the trailing end of the pig, rollers movably supported on the mounting assembly for rotational movement around the longitudinal axis of the pig, for radial movement relative to the longitudinal axis of the pig, and for canting movement in which the rotational axis of each roller can be selectively skewed with respect to a chord of the diametric cross-section of a pipeline in which the apparatus is located, with the longitudinal axis of the pig coinciding with the longitudinal axis of the pipeline. Resilient biasing means is provided for constantly urging the rollers radially outwardly with respect to the longitudinal axis of the pig. A plurality of spaced surface treating elements are rotatably carried on the mounting assembly for rotation about the longitudinal axis of the pig.

US Classification:

Abstract:

A method for distributing fluid along the interior wall of a pipeline wherein a quantity of fluid is placed at a location in the pipeline and exposed at one side to a force acting in an axial and rotational direction. This force will cause at least a portion of the fluid to enter a helical path adjacent the pipeline which will force the material to be coated on the inner wall of the pipeline. As the fluid is coated on the pipeline wall it is exposed to an axial wiping force which smooths out the fluid coated onto the inner wall of the pipeline by removing the excess material.
