Methods and apparatus for applying a uniform application of an appropriate quantity of lubricant to the internal threads of a pipe. In general, the apparatus includes a high pressure supply of lubricant and a high speed, rotating centrifugal applicator for evenly applying the lubricant to internal threads. The system also includes a dosing system to regulate the distribution of lubricant by dispensing a consistent volume of lubricant at each application. Potential advantages of the embodiments include the repeatability and consistency of amount of lubricant on pipe threads (e.g. thickness).
