Straightness alloy steel Heavy Weight Drill Pipe DCDMA Standard AQ BQ NQ HQ PQ
Straightness alloy steel Heavy Weight Drill Pipe AQ BQ NQ HQ PQ
Specifications:
Q series thread drill rods are the undisputed, worldwide choice for wireline coring drill rods.
1. High quality alloy tube
2. Thru-wall heat treated tube body
3. Consistent concentricity, straightness
4. DCDMA standard
Features:
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
