Hevi-Wate Drill Pipe 113Dimensional Data Range III

See page 123 for metric conversions.TAPERED DRILL STRINGS

The ratios of I/C or section moduli between drillcollars and Hevi-Wate drill pipe or drill pipe shouldbe considered to prevent fatigue damage to thesemembers. Experience has indicated that these mem-bers perform best when this ratio is less than 5.5.Tapered drill collar strings are often necessary tomaintain an acceptable ratio. The chart on the next page is based on main-taining an acceptable I/C ratio between Hevi-Watedrill pipe and the drill collars directly below.Example of chart use for 41/2 in. (114.3 mm)Hevi-Wate drill pipe:1. For Directional Holesa. Enter chart from bottom at 41/2 in.

Suggested maximum drill collar size = 73/4in. (196.9 mm) OD x standard bore.2. For Straight Holesa. Enter chart from bottom at 41/2 in.
