Threaded joint for pipes |
| abstract |
A threaded joint for pipes comprising a pin and a box, each having a contact surface including a threaded portion and an unthreaded metal contact portion is provided. The unthreaded metal contact portion includes a sealing surface and a shoulder surface. A non-contacting region is present between the sealing surfaces and the shoulder surfaces of the pin and the box. The threaded joint has one or more grooves formed in the shoulder surface of at least one of the pin and the box and extending to the non-contacting region and to an interior of the threaded joint. The contact surface of at least one of the pin and the box has a solid lubricating coating exhibiting plastic or viscoplastic rheological behavior formed thereon. A total volume V (mm3) of the grooves and a coating weight W (g) of the solid lubricating coating satisfy the equation V/W >= 24 (mm3/g). |
