Rotaries, Blocks, and Swivels - Part 1: The Swivel (DVD)
Catalog No. 65.1070
Rotaries, Blocks, and Swivels Series Part 1
The swivel is a rather remarkable piece of equipment. When rotary drilling first began, there was no precedent for a machine which could do all the tasks they wanted this piece to do. It haas to support the whole weight of the drill string, permit the drill string to rotate, and afford a pressure-tight seal and passageway for drilling mud to be pumped down inside the drill string. This video presentation explains the function, workings, and maintenance of the swivel with an eye to longer equipment life and increased personnel safety on the rig. Produced in cooperation with Continental Emsco-LTV. 1980, 19 minutes, 139 slides, script.
