Abstract

406,878. Boring earth. VEREINIGTE STAHLWERK AKT.-GES., 67, Breitestrasse, Dusseldorf, Germany. April 13, 1933, No. 11090. Convention date, Jan. 14. [Class 85.] In a drill pipe for deep-boring work each section 1 is strengthened at or near its middle by an internal thickening 2 which is preferably rolled on the section by a pilger mill having an offset mandril and is tapered at one or both ends to produce a smooth passage for the rinsing fluid. This construction enables sections of greater length to be used. The ends of the sections, provided with the usual coarse connecting thread, may also be thickened internally, the thickenings being tapered at the end remote from the thread.
