DEVICE AND METHOD FOR APPLYING LUBRICANT TO SCREW THREAD SECTION OF STEEL PIPE |
摘要 |
A lubricant application apparatus which can thinly and uniformly apply a highly viscous lubricant on the threaded portion of a threaded joint for pipes comprises a steel pipe support unit 2 which supports a steel pipe P having a pin 8a while rotating the pipe; a lubricant circulation system 3 in which a lubricant 9 having its viscosity adjusted so as to be sprayable is circulated; a metering unit 4a having a metering pump capable of metering the lubricant 9; a lubricant spraying unit 5a having spray guns 19 and 20 for spraying lubricant through nozzles 19a and 20a toward the pin 8a; a spray gun support unit 6 which supports the spray guns 19 and 20 so as to be movable in the axial and/or radial directions of the steel pipe P; and a controlling unit 7 which controls the rotational speed of the steel pipe P by the steel pipe support unit 2 and the speeds of movement of the spray guns 19 and 20 by the spray gun support unit 6. |
