TUBULAR CONNECTION WITH SLOTTED THREADS

摘要

A connection for the quick and functionally reliable connection of tubulars including pipes (1a) and casing (2a). The connection having a male (1a) or p in end and a mating female (2a), box, or socket end and sections of circumferentially and axially extending protuberances that are threaded segments (CP) or lugs interrupted by slots extending circumferentially (S) a nd axially approximately the same direction as the corresponding protuberance section. Both the pin and box have matching or corresponding arrays of interrupted threads and slots. When properly aligned, the array will be accepted by a corresponding slot when mating the pin and box. After proper mating, the connection is secured by rotation the pin or box to further mate the corresponding patches of the pin and the box.
