Rotary roller bits IADC637 9 7/8 ” (250.8mm)
Product Description
Wholesale API TCI tricone drill bits ine mutengo wakadzikiswa mustock kubva kuChina fekitori kune yakaoma mafomati.
Bit Description:
IADC: 637 - TCI jenari yakavharwa bhiti ine geji chengetedzo yepakati yakaoma maumbirwo ane yakakwirira yekumanikidza simba.
Compressive Strength:
100 - 150 MPA
14,500 - 23,000 PSI
Ground Description:
Matombo akaoma, akaumbwa zvakanaka akadai se: hard silica limestones, quarzite streaks, pyrite ores, hematite ores, magnetite ores, chromium ores, phosphorite ores uye granite.
Far Eastern Drilling inogona kupa TCI bits mumhando dzakasiyana dzehukuru (kubva pa3 3/8" kusvika 26") uye ese akawanda eIADC makodhi.
9 7/8" i250mm mudhayamita, iyo tambo yekubatanidza ndeye 6 5/8 reg pini zvinoenderana neiyo API yakatarwa.
IADC537 zvinoreva kuti trione roller bit inokodzera kuchera matombo akaomarara senge quarzite streaks,granites, etc. The bearing is elastomer sealed kuti uwedzere hupenyu hwekushanda.
Tungsten carbide inserts(TCI) yakaoma kwazvo alloy pakuboora matombo akaomarara, chitsitsinho chemakoni uye ruoko-musana zvakazara zvakaiswa nemazino eTungsten Carbide.
Iyo saizi yakajairika mumunda wemigodhi, kuchera gomba rinoputika. Mukuchera mugodhi, nhamba yekutanga yeIADC kodhi inowanzoita 6,7,8, uye nhamba yechitatu inowanzova 2 ne5.
Zvinoenderana neIADC mataurirwo etricone bit,"2" zvinoreva yakavhurika inotakura roller bit, uye "5" zvinoreva yakavharwa roller inotakura bhiti ine geji dziviriro.
Mune dzimwe nyika, 9 7/8"(250.8mm) inowanzoshandiswa kuchera mvura mutsime uye geothermal tsime. Drill rig inofambiswa nemvura yematope, pachinzvimbo chekumanikidza mweya.
Naizvozvo, kune akasiyana maapplication, isu tinofanirwa kusarudza iyo chaiyo trione roller bits.
