摘要： A threaded joint for steel pipes comprises a pin (1) and a box (2). The pin has male thread (11), a sealing surface (13), and a shoulder surface (14) located on the end face of the pin. Correspondingly, the box has female thread (21), a sealing surface (23), and a shoulder surface (24) which can mate or contact with the corresponding portions of the pin. The shoulder surface (14) of the pin (1) is provided at an end face of the pin. The sealing surface (13) of the pin (1) is located on a pipe end side near the male thread (11). A a nose portion (15) is provided on the pin (1) between the sealing surface (13) and the shoulder surface (14), the nose portion (15) being not in contact with a corresponding portion of the box (2).

摘要： Use of a sealing material which is a multifilament or spun yarn coated with a joint sealing composition to seal a joint in a pipe system in which system a fluid having corrosion inhibitors such as diammonium dimolybdate or benzotriazole; and/or sludge removers; and/or an alcohol such as propane diol, or ethylene glycol; and/or a hydrocarbon such as diesel, including biodiesel, fuel oil, or hydraulic oil; and/or steam at a temperature of at least 180oC and a pressure of at least 10 bar (1000kPa); is to be passed through the sealed joint. It is surprising that the sealing materials of the invention can maintain a sealed joint despite exposure to such materials.

摘要： Described is a mobile phase fitting having reduced corrosion and erosion. The fitting includes a coupling body, compression screw, compression member and gasket. The coupling body has a threaded bore at one end, a tapered cavity, a narrow bore and a fluid channel. The compression screw has an axial bore to receive a tube and a threaded outer surface in engagement with the threaded bore of the coupling body. The compression member is disposed in the tapered cavity and has an axial opening to pass the tube and a tapered surface to engage a surface of the tapered cavity. The gasket is disposed in the narrow bore and has one surface in contact with the first internal surface and has a parallel surface to receive an end face of the tube. Mobile phase flows along a path that includes the tube, an opening in the gasket and the fluid channel.

摘要： This invention provides a threaded connection for pipe or tube that has a non-sticky surface and that suppresses the occurrence of rust and exhibits excellent galling resistance and airtightness even in an extremely low temperature environment without using compound grease, a method of producing the same, and a composition for forming a solid lubricating coating on the threaded connection. A solid lubricating coating (24) formed from a composition containing a binder, a fluorine addition agent, a solid lubricant and a rust proof addition agent is coated as a topmost surface treatment coating on a contact surface of at least one of a pin and a box. Even when exposed to an extremely low temperature environment, the solid lubricating coating (24) can maintain adhesiveness and exhibit a lubricating function, can suppress the occurrence of galling of a threaded connection, and can also secure airtightness after fastening.

摘要： Provided is a threaded joint for heavy-walled oil country tubular goods which can acquire both the ensuring of sealability and the prevention of galling in a state where a high external pressure is also applied to the threaded joint in addition to a high compressive force.
A surface of a pin 3 side which forms a seal portion 13 and a surface of a box 1 side which forms a seal portion 11 are formed into a convex curved surface and a tapered surface respectively. With respect to the pin 3, a seal thickness t s of the pin is set to 15 mm or less, a shape parameter t s /D (D: outer diameter of a pin raw pipe portion) is set to 0.045 or more, and a complete thread length ratio L/t (L: complete thread length of the pin, t: wall thickness of the pin raw pipe portion) is set to 4.0 or less.-
