Abstract
866,995. Pipe joints. ATLAS BRADFORD CO. Nov. 24, 1958 [Oct. 1, 1958], No. 37740/58. Class 99(1). A well pipe joint has a threaded pin and box in which the threads are tapered between 1 1/16 inches and 1 3/16 inches per foot run and have back faces which are at an angle between 7 and 7¢ degrees to a plane perpendicular to the pipe axis. The threads may be of buttress form, Fig. 5, having a depth between 0À22 and 0À26 times the pitch with a front face inclined at 45 degrees to the pipe axis. A sealing ring 15, Fig. 4, e.g. of tetrafluorethylene may be compressed in a groove 14 in the box 2 by the thread 13 of the pin 6 and to prevent extrusion of the ring 15 a smooth nose part 16 is arranged to project across the groove 14 before the ring is compressed by the thread on make up of the joint. Specification 866,996 is referred to.
