HTW Drill Rods 1.5M 3M Length For Wireline Diamond Core Drilling
China Btw, Ntw, Htw Wireline Drilling Rods
We manufacture
Roschen Drilling Products flush joint casing and drilling rods are recognized worldwide for their quality. Our rods and casing are threaded by a qualified team with many years of experience in drilling product
manufacturing. Each and every rod and casing undergoes strict quality control throughout the entire manufacturing process.
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.
