发明名称 Protector for threaded connections
摘要 An improved pipe coupling protector including a thread protector with sleeve is disclosed. Moreover, a method of installation is also set forth. When manufactured, the sleeve is sized to fit over the threads on the exterior of a pipe end and has a surrounding end shoulder with a transverse cap. An undercut defines the cap for removal by puncturing action to enable the sleeve to move up the threads. At the time of installation, the pipe is threaded to a coupling. A lubricant or sealant is applied to the threads. The coupling and the sleeve of the present disclosure completely cover over the threads and they are sealed against atmospheric intrusion and capillary fluid flow along threads and at the coupling face by the sleeve with an underlying layer of sealant or lubricant.
