Kev nce qib hauv Drill Pipe Technology: Txhim kho kev ntseeg tau thiab kev ua tau zoo
Hauv kev tshawb nrhiav kom txhim kho kev ntseeg tau thiab ruaj khov ntawm cov kav dej tho, Hongfengda (HFD) Lub Tuam Txhab tau pib taug kev ntawm kev tsim kho tshiab thiab kev nqis peev. Kev hloov los ntawm phau ntawv sib cais cov cav tov nrog ob-meter laum kav mus rau cov cav tov tsis siv neeg uas tsim peb-meter tho kav dej qhia txog qhov tseem ceeb hauv kev lag luam.
Txhawm rau kom ntseeg tau cov qauv zoo tshaj plaws, HFD tau tsim lub xeev-ntawm-tus-kos duab tho yeeb nkab ntau lawm rhiav. Kev nqis peev ntau heev tau ua kom tau txais cov cuab yeej siv siab tshaj plaws, suav nrog kev sib txhuam vuam tshuab, tiaj tus forging hydraulic tshuab, thiab cov tshuab xuab zeb blasting. Cov kev nqis peev no qhia txog HFD txoj kev cog lus kom xa cov kev daws teeb meem rau nws cov neeg siv khoom.
Nyob rau hauv cov nqe lus ntawm kev xaiv cov khoom, HFD siv 45Mn2 high-zoo alloy geological kav paub rau lawv tshwj xeeb lub zog thiab durability. Los ntawm kev ua tib zoo ua nrog rau cov cua kub ncaj qha ncaj qha thiab tiaj tus forging hydraulic tshuab, cov kav dej no tsis muaj.rgo nruj shaping thiab vuam txheej txheem kom tshem tawm cov teeb meem dabtsi yog khoov thiab deformation.
Ib qho ntawm cov kev hloov tshiab tseem ceeb tau qhia los ntawm HFD yog kev txhim kho ntawm cov tho yeeb nkab sib txuas. Los ntawm kev ua haujlwm 35 molybdenum zoo hlau thiab ua rau lawv cov txheej txheem kev kho cua sov, nrog rau kev kub siab annealing, nruab nrab-kub modulated annealing, thiab tag nrho oxidation, lub tuam txhab ua kom superior corrosion kuj thiab nce hardness. Qhov kev ua kom zoo zoo no ua rau txhim kho lub zog torque-tiv taus ntawm lub laum yeeb nkab thiab txhim kho nws tag nrho cov kav ntev.
Tsis tas li ntawd, HFD qhov tsom rau ntawm qhov chaw vuam ntawm cov tho yeeb nkab pier coarse ua kom pom kev txhawb nqa thiab nce hnav tsis kam. Los ntawm kev nthuav dav qhov chaw vuam ntawm qhov sib txuas ntawm cov yeeb nkab tho thiab cov yeeb nkab steel hlau, HFD ua tiav cov khoom zoo tshaj plaws thiab kev ua haujlwm ntev, ua tau raws li cov qauv kev lag luam nruj tshaj plaws.
Nyob rau hauv cov ntsiab lus, HFD kev saws me nyuam ntawm cov cuab yeej siv siab heev thiab nruj tswj kev ntsuas tau hloov pauv cov txheej txheem laum yeeb nkab. Lub tuam txhab txoj kev mob siab rau kev tsim kho tshiab thiab kev ua tau zoo ua kom cov neeg siv khoom tau txais cov khoom tsis muaj kev ntseeg siab thiab kev ua tau zoo. Raws li HFD txuas ntxiv thawb cov ciam teb ntawm kev nce qib thev naus laus zis, nws tseem nyob ntawm qhov ua ntej ntawm kev lag luam, teeb tsa cov qauv tshiab rau kev ua tau zoo thiab kev ua haujlwm zoo.
