摘要： A threaded joint for steel pipes comprising a pin (1) and a box (2). The pin has a male thread (11) and a lip (12) which comprises (i) a sealing surface (13) and (ii) a nose portion (16) provided with a shoulder surface. The box has a female thread (21), a sealing surface (23) and a shoulder surface. The shoulder surface of the pin comprises two distinct adjacent surfaces, main shoulder (14) in the inner side and sub shoulder (15) in the outer side. Correspondingly, the shoulder surface of the box comprises two distinct adjacent surfaces, main shoulder (24) in the inner side and sub shoulder (25) in the outer side. The main shoulder surfaces of the pin and box are disposed such as to prevent a radially inward deformation of the lip end, and the sub shoulder surfaces of pin and box are disposed such as to limit a radially outward deformation of the lip end. The main shoulder of the pin has a greater radial dimension than said sub shoulder of the pin, and at least the main shoulder surface of the pin is in axial abutment with at least the corresponding main shoulder surface of the box.

摘要： A tubular threaded joint which has excellent resistance to compression and which permits easy tightening operation in the field in a vertical state comprises a pin having a male threaded zone and a box having a female threaded zone. The pin or the box has an end shoulder surface on its end, and the other member has a shoulder surface which abuts against the end shoulder surface. The screw threads of the male threaded zone and the female threaded zone are trapezoidal threads having a crest, a load flank, and a stabbing flank. The lip length, which is the distance in the axial direction of a member having an end shoulder surface between the end shoulder surface and the closest engaged thread to that surface, is at least 140 times the stabbing flank clearance, which is the distance in the axial direction between the stabbing flanks of the male thread and the female thread when the load flanks of the male and female threads contact each other. The stabbing flank of the male thread is preferably chamfered.

摘要： An apparatus for and a method of measuring an outer diameter of a worked portion at a pipe end, by which an outer diameter of an end of pipe of various sizes is rapidly and precisely measured; the apparatus comprising a main arm (1), a lower gauge head support arm (2), a bearing roller arm (3), an upper gauge head support arm (4), a presser roller arm (5), a position fixing metal fitting (6), a gauge head (14b) supported by the arm (2) to be movable horizontally and vertically, a gauge head (15b) supported by the arm (4) to be movable horizontally and vertically, and gauge heads (14a, 15a) which are movable vertically. An outer diameter of an article being measured is measured by the gauge heads while the article is rotatably held by rollers (10a, 10b, 11a, 11b) on the arms (3, 5). The measurement can be effected simultaneously at two locations in a lengthwise direction of the article being measured.
