API 6A li qub yog dab tsi?
API 6A tus qauv qhia txog kev ua tau zoo, tsim qauv, cov ntaub ntawv, kev sim, thiab kev soj ntsuam cov khoom siv rau kev siv cov khoom siv drilling, npog cov khoom siv tshwj xeeb xws li lub rooj vag blowout inhibiters, annular blowout preventers, hydraulic fittings, thiab drilling fours. Tus txheej txheem qhia meej txog kev ua haujlwm ntawm cov khoom siv nyob rau hauv lub siab, qhov kub thiab txias, thiab cov dej ntws hauv qab, thiab npog cov ntsiab lus xws li vuam, kos npe, khaws cia, thiab kev thauj mus los. Raws li cov txheej txheem tseem ceeb rau API daim ntawv pov thawj, qhov kev qhia tshwj xeeb no tau siv dav hauv kev lag luam roj av thoob ntiaj teb.
