Abstract: A threaded connection for pipe in which the axial distance between the box intermediate shoulder surface and the box end shoulder surface of the box before make-up, LB, is larger than the axial distance between the pin intermediate shoulder surface and the pin end shoulder surface of the pin before make-up, LP, such that, upon completion of make-up, the pin and box intermediate shoulder surfaces and are in contact and function as torque shoulders, while the pin and box end shoulder surfaces are in light (or no) contact. The difference between the axial distances, (LB?LP), is such that, when the pin and box are made up and upon application of an axial compressive load, the pin and box are slightly axially compressed by the compressive load and the pin end shoulder surface comes into pressure contact with the box end shoulder surface to bear part of the compressive load.
