WT THREAD TUBING

Standard DCDMA W sizes allow nesting of 
other W casing.

THREAD DESIGN

Double-butt tapered joint and heavy duty buttress thread provide greater torsion and pullback strength to allow retrieval from difficult ground conditions and repeated use. The tapered joint and coarse thread (2.5 threads per inch) reduces stress resulting in easier and faster make and break for reduced wear and reduced labor costs. Threads are easier to clean due to wider spacing for situations where casing is reused. Compatible with HD rod threads .
