Abstract: A lubricating coating which is free from harmful heavy metals is formed on a premium threaded joint for pipes constituted by a pin and a box each having a contact surface comprising a threaded portion and an unthreaded metal contact portion (a sealing surface and shoulder) in order to provide the joint with galling resistance, gas-tightness, and anticorrosive properties such that the unthreaded metal contact portion is prevented from yielding even when the joint is made up with a high torque. The lubricating coating comprises one or both of a rosin and calcium fluoride; metal soap; wax; and a basic metal salt of an aromatic organic acid, and preferably it further includes a lubricating powder, magnesium carbonate, and/or a carbohydrate, particularly a cyclodextrin.

Abstract: This invention relates to a threaded joint for steel pipes which comprises a pin and a box each having a contact surface including a threaded portion and an unthreaded metal contact portion and which guarantees galling resistance and gas tightness in a stable manner without application of a compound grease. A solid lubricating coating comprising a lubricating powder (e.g., molybdenum disulfide) and an organic or inorganic binder is formed on the contact surface of at least one of the pin and the box. The proportion of area of a cross section along the thickness of the solid lubricating coating which is occupied by secondary particles of the lubricating powder having an equivalent circular diameter of 15-60 &mgr;m is from 5-90%. Alternatively, the solid lubricating coating comprises, in addition to the lubricating powder, a fibrous filler (e.g., inorganic whiskers) in such an amount that the mass ratio of the fibrous filler to the binder is 0.01-0.5. As a result, galling resistance is improved, particularly at high temperatures.
