ABSTRACT:
A protector for easy and quick installation on and removal from the threaded end of a pipe, such as well casing or tubing, when making up a string of well casing or tubing for insertion into a well bore. The protector includes a tension belt constructed in a manner to resiliently bias the protector toward open position with the ends of the tension belt being interconnected by a latching device having an integral handle associated therewith with the tension belt being encapsulated by a resilient body to protect the threads of the pipe. The latching device and associated handle structure is recessed into the body and related housing structure so that no components project beyond the periphery of the resilient body. The handle structure includes a unique undercut portion enabling the finger or fingers to move the operating end of the handle outwardly of the body and also a hook structure for engagement over an inclined guy wire for gravity movement of the protector back to a point adjacent the pipe rack for attachment to a section of casing or tubing to be moved from the pipe rack into position for connection with a joint of casing already in the well bore. The resilient body of the protector is constructed of a readily distinguishable color and provided with rounded corners to enable it to more easily slide over objects or obstructions.
