ABSTRACT:
A connector for connecting two pipes has threads configured to improve making up in severe motion conditions. The connector includes a pin and a box, each having frusto-conical surfaces with helical threads formed on them. The threads have multiple starts for rapid make up. The crest of each thread is truncated and is a frusto-conical surface. This frusto-conical surface is inverted to the frusto-conical surface of the portions of the pin and box that contain threads. Each thread has a load flank and a stabbing flank. The stabbing flank inclines and joins a link flank, which in turn joins a root. The link flank inclines at a different and steeper angle than the stabbing flank.
