NW HW HWT Wireline Casing Pipe Core Drilling Casing Tube 3m 1.5m
Characteristics
1. Our NW HW PW casing tubes are of the highest quality ,are manufactured to exacting specifications using advancing maching technoogy.
2. They are manufactured from seamless steel tube by cold drawn.The material is XJY850/30CrMnSiA which meets the global standard.
3. Drill rods are made from quality heat treated materials which ensure superior strength, wear resistance and toughness in the most demanding applications
4. Rods and casing are manufactured under stringent industry standards, and are field tested under a variety of conditions.
5. All rods are designed to be compatible with other rods manufactured to the standard DCDMA
Application
Q thread rods are the undisputed, worldwide choice for wireline coring drill rods.
2. thru-wall heat treated tube body
3. consistent concentricity, straightness
4. tapered threads
TUBING
• High quality alloy steel tubing
• Consistent concentricity, straightness and heat treatment
• All tubing available in DCDMA sizes
THREAD
• Tapered, course threads (3 threads per inch) provides easy make and break
• Load efficiency of 30% provides sufficient strength for average applications
THRU-WALL HEAT TREATMENT
• Provides 140% material strength
• Heat treated box threads significantly increases thread wear life
CASE HARDENING
• Significant research, development and field testing has resulted in a hardening process that is unmatched in the marketplace
• Pin thread crest is hardened to nominal 55 HRc to eliminate damaging ‘adhesion’ wear
• Eliminates the transfer of wear material back and forth which is what happens between threads of equal hardness, leading to large scale galling and joint seizing
