Introduction of Company
Hejian RuiDa Petroleum Material Co., Ltd. is a Chinese supplier of drilling tools since 1998.We specializes in Tricone bits,steel tooth bit,TCI tricone bits,PDC bit,diamond drill bits,reamer bits(hole opener),diamond core bits,single cone bit,for water well,mining,petroleum&gas,oilfield,construction and underground foundation and geothermal,directional boring,at work all over the world.
All of our products are in accord with API and ISO standards.
The advantage of using a tricone bit
1. There is a tri cone suitable for any formation 2. Tricone bits are versatile and can handle changing formations
3. Tricones are reasonably priced with long life and good rate of drilling
Depending on ur application,we can provide u with new,rerun or premium oil field quality tricone bits,
the difference between a premium oil field tricone bit and nonpremium oil well quality tricone is that the roller cones have high end sealed bearings: extremely high quality tungsten carbide and offer diamond gauge protection throughout the drill bit. These roller cone bits are designed to go to extreme depths in extreme conditions and in situations where they cannot fail.
Our tci tricone bit range in size from 3" to 26"
Our mill tooth tricone bit range in size from 3" to 26"
Main Feature:
1.Cutting Structure
The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.
2.Gauge Structure
Multiple gauge protection with gauge trimmers on heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
3.Bearing Structure
High precision bearing with two thrust faces. Balls lock the cone.Hardface heard bearing surface. Cone bearing inlaid with friction-reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved and suitable for high rotary speed.
4.Seal and Lubrication
The advanced metal seal package consists of two metal seats and two elastic energizers. Compressed energizers ensure good contact being kept on two sealing surfaces of metal rings by elastic force, and achieve the bearing seal. In the drilling, metal seal are relatively dynamic, and the energizers are static. This will improve the reliability and durability of bearing seal. The pressure compensator system and advanced grease can greatly increase the lubricating reliability.
