International Classification:
E21B 1900
US Classification:
166 90
Abstract:
A system for washing, cleaning, and chemically treating sections of drill pipe being tripped out of the hole, which includes an elongated cylindrical housing having a central opening therethrough, the housing comprised of a first and second semi-circular sections, the sections movable between open and closed positions by a hinged joint along one edge, and in the closed position maintained closed via a locking member along the second edge. Within the housing there is further included upper and lower wipers, which comprise circular rubberized material having bores along their central axes, the bores being substantially the width of a section of drill pipe to clean the wall of the pipe. Each wiper would be spaced apart from one another and housed within an annular channel along the inner surface of the housing so that the wipers would be stationary within the housing as the housing is placed in the closed position. There is provided spray nozzles for providing pressurized spray of water and anti-corrosive compound for coating the pipe wall.

US Classification:
166 90
Abstract:
What is provided is a system for washing and cleaning sections of drill pipe being tripped out of the hole, and the system including a cylindrical housing having a central opening therethrough, the cover sections movable between open and closed positions by hinged joint along one edge, utilizing a system of hydraulic system cylinders, and in the closed position, maintain closed for defining a chamber therewithin. Within the housing chamber there is further included a wiper member, which comprises a circular member of rubberized material having a bore through its central axis through which sections of pipe travel during the cleaning process, the bore being a width so as to frictionally engage and wipe the wall of a section of drill pipe. The wiper would be spaced apart from the housing and housed within an annular channel along the inner surface of the housing so that the wiper would be stationary within the housing as the housing is placed in the closed position.
