Our wireline drill rods are all manufactured by CNC machines under
DCDMA standard. They're made of
high quality alloy steel with heat-treated. We also can produce
various sizes of casing tubes.
Drill pipes will be manufactured from seamless steel tube by cold
The material is XJY850 / 30CrMnSiA which is one of the best
material for geological drilling in China.
Coring rods are crafted from quality heat treated materials
ensuring superior wear resistance, strength,
and toughness in the most demanding applications.
Rods and casing are manufactured under stringent industry
standards, and are field tested under a variety
All rods are designed to be compatible with other rods manufactured
to DCDMA standards.
• High quality alloy steel tubing
• Consistent concentricity, straightness and heat treatment
• All tubing available in DCDMA sizes
• Tapered, course threads (3 threads per inch) provides easy make
• Load efficiency of 30% provides sufficient strength for average
THRU-WALL HEAT TREATMENT
• Provides 140% material strength
• Heat treated box threads significantly increases thread wear life
