摘要： A lubricating coating which can prevent the occurrence of galling even when makeup is carried out with a high torque and which has excellent rust preventing properties is formed on the contact surfaces of a pin and/or a box of a tubular threaded joint. The lubricating coating contains copolymer particles made from particles of an acrylic-silicone copolymer with an average particle diameter of 10 - 50 μm dispersed in a highly viscous matrix made from a mixture of a rosin-based substance selected from rosin and its derivatives, wax, a metal soap, and a basic metal salt of an aromatic organic acid (such as highly basic Ca sulfonate).

摘要： A threaded tubular connection including a first tube and a second tube is provided. The first tube includes a pin member which extends from an end of a main body of the first tube to a terminal end of the first tube. The second tube includes a box member which extends from an end of a main body of the second tube to a terminal end of the second tube. A cross-sectional area of a pin critical cross-section is within approximately ±5% of cross-sectional area of a box critical cross-section of the box member. The cross-sectional areas of each of the pin and box critical cross-sections are within approximately ±5% of the sum of the cross-sectional areas of a box intermediate critical cross-section of the box member and a pin intermediate critical cross-section of the pin member.

摘要： A solid lubricating coating formed on a contact surface of a threaded joint for pipes has a matrix of a lubricating oil-containing polymer. The lubricating oil-containing polymer has either a uniform composition or a gradient composition in which the concentration of lubricating oil decreases towards the contact surface and in which there is substantially no lubricating oil in the vicinity of the contact surface.

摘要： A sealed threaded tubular connection which is resistant to successive pressure loads comprises a male element (1) including a male threading (3) and a female element (2) including a female threading (4) corresponding to the male threading (3). At least one of the elements comprises a lip (5) extending beyond the threading (3) to the free end of the element (6) and the other element comprises a recess (10) for the lip (5). The lip (5) comprises a first zone (7) with a peripheral surface turned towards the other element on which a first sealing surface (13) is disposed which can be radially interference fitted against a corresponding second sealing surface (11) disposed on the peripheral surface of the recess (10) of the other element. The lip (5) has a second axially located zone (8) between said first zone (7) and the free end of the element (6) which comprises a first radial bearing surface (14) turned towards the other element in contact with a corresponding second radial bearing surface (12) disposed on the peripheral surface of the recess (10) of the other element. The first and second zones (7, 8) are axially separated by a third zone (9) with a radial stiffness which is lower than the first and second zones (7, 8). This third zone (9) is capable of being radially deformed towards the other element by a pressure exerted thereon.
