Patent number: 8622091Abstract: A protector which prevents damage to a solid lubricating coating on a threaded portion of a threaded joint when the protector is mounted on a pin or a box of a threaded joint for pipes in which at least one of the pin or the box is lubricated with a solid lubricating coating comprises a tubular member having a threaded portion on its inner or outer peripheral surface which threadingly engages with at least a portion and preferably 3-5 complete threads of the threaded portion provided on the pin or the box to be protected. The thread height H1 of the threaded portion of the protector and the thread height H2 of the complete thread of the pin or the box on which the protector is mounted satisfy H1>H2, and the difference between H1 and H2 [=H1?H2] is larger than the maximum coating thickness at the thread crest of the solid lubricating coating which covers the threaded portion of the pin or the box.Type: GrantFiled: August 14, 2008Date of Patent: January 7, 2014Assignees: Nippon Steel & Sumitomo Metal Corporation, Drilltec Patents & Technologies Company, Inc.Inventors: Yasuhiro Yamamoto, Shigeo Nagasaku, David W.
