摘要： A threaded joint for steel pipes having excellent galling resistance, rust preventing properties, and airtightness without using a compound grease comprises a pin and a box each having a threaded portion and an unthreaded metal-to-metal contact portion serving as contact surfaces. The contact surfaces of at least one of the pin and the box are coated with a multi-layered structure comprising, from the bottom, a first layer formed from a first metal or alloy, a second layer formed from a second metal or alloy which is softer than the first metal or alloy, and an uppermost layer of a solid lubricating coating comprising a lubricating powder in an organic or inorganic binder.

摘要： A pin-box type threaded joint for steel tubes having a contact surface (30) including a threaded portion and a nonthreaded metal-to-metal contact portion has improved leak resistance, galling resistance, and corrosion resistance particularly to crevice corrosion. The contact surface of at least one of the pin and the box is coated with a first plating layer (34) made of a Cu-Zn alloy or a Cu-Zn-M1 alloy (wherein M1 is at least one element selected from Sn, Bi, and In). Optionally, an undercoat (32) of one or both of a Ni plating layer (32a) and a Cu plating layer (32b) and an overcoat of a Sn-M2 alloy plating layer (36) (wherein M2 is one or more elements selected from Bi, In, Ni, Zn, and Cu) may be formed below and above the first layer, respectively. A solid lubricating coating (38a) and a viscous liquid or semisolid lubricating coating (38b) may also be formed atop the plating layer as a lubricating coating (38).

摘要： A threaded joint for steel pipes comprised of a pin 1 and a box 2 each having a threaded portion (1a, 2a) and an unthreaded metal contact portion (1b, 2b) exhibits adequate leakage resistance and galling resistance when used for makeup of oil country tubular goods with application of a green dope or even without any dope. The threaded joint has a first plating layer of Sn-Bi alloy plating or Sn-Bi-Cu alloy plating formed on the contact surface of at least one of the pin 1 and the box 2. The first plating layer may have a second plating layer selected from Sn plating, Cu plating, and Ni plating on its lower side and at least one layer of a lubricating coating, and particularly a solid lubricating coating, on its upper side.
