7 7/8"(200.0mm) IADC517 Soft Rock Drilling TCI Tricone Bit API Standard
Tricone Bits - 7 7/8''
|Cone Size||7 7/8"|
|Bearing Type||Elastomer Sealed Bearing|
|Circulation Type||Mud Fluid|
|Thread Connection||4 1/2 Reg Pin|
|Application||Soft to medium formation with low
compressive strength ,such as mudstone,
gypsum,salt,soft limestone, etc.
1>Elastomer sealed bearing is a type of bearing in tricone bits sealed system, the bearing is sealed by elastomer O-ring, somebody always call it as "Rubber sealed bearing".
2>IADC517G means tri-cone bits with long chisel or spoon inserts, sealed bearing with tungsten carbide inserts at heel of cones(gauge protection). Long inserts could drill soft rocks with very high penetrating speed(ROP). ROP is very important for evaluating cost performance of tricone bit. In drilling field, longer inserts/teeth could drill faster but softer, shorter teeth/inserts could drill harder but slower.
Choose the correect and suitable IADC code to reach the best cost-effective, we are pleasant to choose the right TCI tricone bits according to your geological information.
