On the pin the first three or four starting threads and the final two threads near the seal and on the box the first two threads near the seal and the last three or four vanishing threads at the back of the box are not engaged (high torque connections designed with less thread taper have more engaged threads). ?m dv%S. Keep in mind for example a 4 1/2XH pin like the one bellow has over 4 meters worth of threads if they were stretched out. The wide range of connections naturally brings up the question about compatibility. Power tools that are not specifically designed for seal refacing should never be used to dress a seal. AC2600 High Power Wi-Fi Router. Interchangeability means that the connections will mate together, make up, and function; however, the performance properties will be limited to those of an API connection. 4 55 It is also my observation that if you can keep a connection in the field working the thread flanks and torque shoulders will harden up from the cold working that occurs every time the connection is made up making them more resistant to mechanical damage. But take the necessary precautions. Innovative thread design Similar collar ID and OD to standard API NC connections Developed to eliminate twist offs and reduce NPT and maintenance costs associated with downhole failures, the XPC* extreme-profile single shoulder connection significantly increases fatigue life over standard API NC connections.
