Hauv kev lag luam roj thiab roj OCTG (Oil Country Tubular Goods) kev lag luam, kev sib txuas ntawm cov khoom siv feem ntau muab faib ua 3 hom tseem ceeb, cov lus qhia tshwj xeeb ntawm txhua hom yog raws li hauv qab no:
Kev sib txuas lus API txheem
Qhov no yog qhov feem ntau siv cov tsoos kev sib txuas txhais los ntawmAPI 5B tus qauv, nws suav nrog peb yam tseem ceeb: STC (Short Round Thread Casing), LTC (Long Round Thread Casing) thiab BTC (Buttress Thread Casing). Nws tso siab rau cov xov sib txuas rau kev sib khi, cov nqi tsim khoom tsawg thiab cov txheej txheem sib txuam yog qhov paub tab, thiab nws yog qhov tsim nyog rau cov pa ntiav ntiav thiab nruab nrab - qhov tob tob nrog cov kev ua haujlwm me me.

FAQ
Q: Koj puas muab NACE MR0175 daim ntawv pov thawj rau qaub (H₂S) daim ntawv thov kev pabcuam?
A: Yog. Tag nrho cov khoom rau corrosive H₂S ib puag ncig (xws li L80-13Cr, 22Cr steel qib) tau ntawv pov thawj rau NACE MR0175 / ISO 15156, thiab peb tuaj yeem muab cov ntaub ntawv tiav kev tshuaj xyuas thiab cov ntaub ntawv kuaj corrosion.
Q: Koj puas txhawb cov qib kev cai steel? Xws li super 13Cr, 22Cr lossis duplex stainless hlau?
A: Yog. Peb tuaj yeem tsim cov kev cai siab - alloy steel qib xws li L80-13Cr, 22Cr, 25Cr thiab 28Cr kom tau raws li cov kev xav tau ntawm cov dej tob, cov roj av qaub thiab ib puag ncig corrosive heev.
Q: Dab tsi yog qhov txawv ntawm koj qhov kev sib txuas API cov qauv thiab kev sib txuas hwm zoo? Thaum twg kuv yuav tsum siv qhov twg?
A: Cov kev sib txuas API Cov Lus Qhia (STC/LTC/BTC) tso siab rau cov xov sib txuas sib txuas, nrog tus nqi qis thiab kev hloov pauv loj, tsim nyog rau cov pa ntiav ntiav thiab nruab nrab- qhov tob tob nrog cov haujlwm me me. Cov kev sib txuas hwm zoo txais cov hlau- mus rau- hlau sealing, nrog lub zog ntau dua thiab kev qaug zog zoo dua, haum rau ultra- qhov dej tob, HPHT gas qhov dej thiab lwm yam kev ua haujlwm hnyav.
