Down The Hole API 2 3/8" Reg 89mm DTH Drill Rod Pipes Drilling
Tubes
Product specifications:
down th hole drill pipes play a significant role in all DTH
drilling, regardless of application, rock type, hole depth or drill
rig. The key features of a high quality DTH tube are durability,
accuracy and manageability. Sinodrills DTH drill pipes are made of
superior alloy and the both thread ends are friction welded to the
seamless steel pipe.The high pressure air is delivered to DTH
hammer by DTH drill pipe, simultaneously it transfers the rotation
and press force to the DTH hammer.
Standard DTH drill pipe:
Diameter: 76mm, 89mm, 102mm, 114mm, 127mm, 140mm,
Length: 1000mm, 1500mm, 2000mm, 3000mm, 5000mm, 6000mm;
Thread: 2 3/8” API REG, 2 7/8” API REG, 3 1/2” API REG, 4 1/2” API
REG, 2 3/8 API IF, 3 1/2 API IF
Special DTH drill pipe:
The drill pipe for Atlas Copco – Ingersol Rand T4, Schramm T64,
Atlas Copco F6, L6 and L8, and the drill pipe for Driltech
D25/D40K.
