Product Description

Product Description

Basical Specification
Size of tricone bit	22 inch 558.8mm
Connection	7 5/8" Reg pin
IADC code	517 537
Bearing	Journal /roller
Sealed	rubber or metal sealed
Operating Parameters
WOB (Weight On Bit)	0.35~1.05 KN/mm (bit Dia.)
Rotary speed	110~40 r/min
Make up torque	8.5~12.2 KN.M
Formation	Medium formation with high compressive strength ,and high drillability ,such as mudstone, gypsum,salt,soft limestone,etc.

Optimal test method for drilling parameters

Drill for 5 minutes with initially selected proper WOB and moderate RPM (60~100r/min) and record the ROP (as shown in the table below).
Moderately inctease WOB and keep the same RPM and drill under this WOB for 5 minutes and again record the RPO (as shown in the table below).
Decrease WOB b the same extent and tepeat step 2.
Find the WOB in the tow groups of test than can yield highest ROP.
Properly change RPM under optimal WOB and record the ROP (as shown in the table below).
Select the RPM at the highest ROP.
Set the drilling parameter at the best combination:60KN RPM: 120r/min 

Times	RPM:100r/min		WOB:60KN
Times	WOB (KN)	Drilling hour (min/m)	RPM (r/min)	Drilling hour (min/m
1	80	8	100	7
2	100	9	120	5.5
3	60	7	80	8
Select	60	7	120	5.5

Q What is the difference between bi-metal, ceramic, chrome-plated, and high-frequency quenching cylinder liners?

A
| Type | Inner Material | Hardness | Service Life | Best For |
| Bi-Metal | High-chromium cast iron | HRC 62 | 800h+ | General high-pressure, abrasive drilling |
| Ceramic | Al₂O₃ or Zirconia | HRC 80+ | 1500h+ | Extreme abrasion, high-sand formations |
| Chrome-Plated | Hard chrome coating | HRC 55 | 300-400h | Moderate conditions, budget operations |
| High-Frequency Quenching | Quenched alloy iron | HRC 50 | 200-300h | Light-duty, low-cost applications |
