API falegaosi o Roller cone bit IADC637 3 7/8″ (98mm) i totonu
Fa'amatalaga o oloa
Fa'atau oloa siisii API TCI tricone roller cone vili bits ma tau fa'aitiitiga i le fa'asoa mai Saina fa'atau mo vili vaieli.
Fa'amatalaga Bit:
IADC: 637 - TCI tusi talaaga fa'amaufa'ailoga fa'amau fa'amau fa'atasi ma fua fa'atatau mo fa'avae malo fa'asolo ma maualuga le malosi fa'amalosi.
Malosi fa'amalosi:
100 - 150 MPA
14,500 - 23,000 PSI
Fa'amatalaga o le eleele:
Ma'a'a ma'a'a ma'a'a lelei e pei o: limestone silica malo, streaks quarzite, pyrite ores, hematite ores, manetite ores, chromium ores, phosphorite ores ma maamora.
E mafai ona matou ofoina atu TCI bits i le tele o lapopoa (mai le 3 3/8" i le 26") ma le tele o tulafono a le IADC.
1> Tungsten carbide faʻapipiʻi e faʻapitoa i luga o cones, puipuiga o fua ma tua o lima.
2> Tungsten carbide inserts e fetaui i luga o fua o cones provents bits mai shrinkage, drillers leai se popole mo le loloto loloto ma maa viliina maa.
3> O-mama mama, Faʻamaufaʻailoga sili ona lelei ma faʻamaufaʻailoga faʻamaufaʻailoga e faʻaleleia ai le faʻamaufaʻailoga. O le fa'atonuga totogi faiga ma fa'apitoa
ole ga'o e matua fa'atuputeleina ai le fa'atuatuaina ole lubricating.
