Technical Work Status Report and Drill Pipe Fatigue Test Machine Monthly Progress Report

摘要

Minor modifications were made of the subcontract to design and procure an electric power sub. Finer detail was established for the specifications of the electrical equipment. Major effort in the design and construction of a full-scale drill pipe fatigue test machine was directed towards detail design of the rocker arm, the load link, and the installation of the roller bearings associated with these elements and those for the rocker arm supports and the pitman connection. Titanium drill pipe extrusion investigations consisted of preliminary experimental piercing, bare extrusion, steel jacketed extrusion, and copper jacketed extrusion on a 3,850-ton press in preparation for full-scale extrusion on an 8,000-ton press.
