Abstract
A lubrication device, a lubrication system and a method are for applying a lubricant from a lubricating-fluid reservoir to an internal threaded portion of a pipe body. The lubrication device includes: a rotary device having: first and second coupling parts, and fluid passage for carrying the lubricant from the first coupling part to the second coupling part. The first and the second coupling parts are arranged to rotate relative to each other around an axis that coincides in the main with the longitudinal axis of the pipe body. An applicator body is connected to the second coupling part to allow rotation around the rotational axis of the rotary device. The applicator body has a fluid passage with an outlet for carrying the fluid to the applicator surface as the fluid passage in the applicator body is in fluid communication with a corresponding fluid passage in the rotary device.
