High quality 9 1/2"IADC 437 TCI tricone bits
Specification of TCI Roller tricone bits:
Application standards:
The tricone bit produced by our company conforms to international drilling contractor association-IADC code
According to partical experiences of home and abroad:
We recommend the weight on bit, rotary speed requirement,and air requirements to customers
The weight on TCI bits:
According to pratical experiences of home and abroad,The selection of drilling pressure should
consider the physical andmechanical properties of rock and the drillability of rock, the bearing
capacity of bit and the technical performance of drill rig.
Rotary Speed Requirement
Experience has shown that under such circumstances that the cuttings can be well removed from
the hole, the RPM possesses of a proximatelinear relationship with penetration rate within a certain
range. As the RPM is increased, the penetration rate will increase with relation to formation
characteristics.
Air Requirements:
Compressed air is widely used for blowing cuttings in rotary blast hold drilling rig. It serves two
important functions; One isto clean and remove cuttings from the hole bottom with sufficient air
volume, and the other is to cool and flush the bearing surfaces of bit for increasing rotary speed
and obtaining longer bit life.
