TUBULAR THREADED JOINT HAVING IMPROVED LOW TEMPERATURE PERFORMANCE |
摘要 |
In order to provide a tubular threaded joint constituted by a pin and a box each having threads and an unthreaded metal contact portion with excellent galling resistance and gas tightness even in extremely cold environments at -60 °C to -20 °C and rust preventing properties without using a compound grease, a thermoplastic solid lubricating coating containing low friction copolymer particles made from an acrylic-silicone copolymer and preferably further containing a solid lubricant (e.g., graphite) in a thermoplastic polymer matrix (e.g., selected from polyolefin resins and ethylene-vinyl acetate copolymer resins) is formed on the surface of the threads and unthreaded metal contact portion of a pin and/or a box. |
