Q WIRELINE CORING ROD

Q Thread is Roschen's original wireline thread and continues to be the industry standard for wireline coring threads. The proprietary tapered threads provide additional strength, making joints easy to make and break. Through innovative engineering and state-of-the-art manufacturing techniques, Q rods are known for quality, strength, and increased thread wear.

TUBING
High quality alloy steel tubing. Consistent concentricity, straightness and heat treatment.

THREAD
Tapered, coarse threads (three threads per inch) provides easy make and break. Load efficiency of 30% provides sufficient strength for average applications.

THRU-WALL HEAT TREATMENT

Heat treated box threads provides 140% material strength which significantly increases thread wear life.

CASE HARDENING
Roschen is the only major manufacturer in the industry to case-harden threads.

Significant research, development and field testing has resulted in a hardening process that is unmatched.

Pin thread crest is hardened to nominal 60HRC to eliminate damaging "adhesion" wear.

Eliminates the transfer of wear material back and forth as seen between threads of equal hardness, leading to large scale wearing and joint seizing.
