5-7/8" Tricone Rock Bit for hard formation.IADC-437/517,3½ API Reg.
(1) Cutting Structure of this series tricone rock bit :
The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.
(2) Gauge Structure of this series tricone rock bit :
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 of this series tricone rock bit :
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 of this series tricone rock bit :
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.
The 437 tci bits are used to drill low compressive strength,very soft formations .TCI bits maximize the use of bothconical and chisel tungsten carbide inserts of large diameters and high projection.This cutting sstructure design,combined with maximum cone offset,results in high bit penetration rates .The deep intermesh of cutter rows prevents bit bailing in sticky formations.
The 517features aggressive chisel tungsten carbide inserts on the heel rows and inner rows.This desing provides a fast drilling rate and added cutting structure durability in medium-to –medium hard formations .The HSN rubber o-ring provides adequate sealing for bearing durability.
The 637bits can be used to drill hard and abrasive formations .Wearresistant tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge.Maximum numbers of bemisphericalshaped inserts are used in all rows to provide cutter durability and long life.
The 617features robust chisel tungsten carbide inserts on the heel row and conical on the inner rows.This design provides a fast drilling rate and added sutti8ng structure durability in medium to medium hard formations .The HSN rubber o-ring [rovodes adequate sea;omg fpr bearomg dirability.
