API 6D, hu ua "Specification for Pipeline and Piping Valves," yog tsim tshwj xeeb rau cov midstream sector -pipelines uas thauj cov roj thiab roj mus ntev. Thaum muaj coob tus neeg koom nrog API 6D nrog loj, trunnion-mounted pob li qub siv nyob rau hauv compressor chaw nres tsheb, tus qauv kuj muaj xws li specifications raufloating pob li qub.

FAQ
Dab tsi yog qhov txawv ntawm API 6D 24th edition thiab 25th edition?
25th tsab xav kom cov actuators ua raws li API 6DX. Hauv 24th tsab, tsuas yog API 6DX cov cai rau sizing tus actuator yuav tsum tau. Qhov no txhais tau hais tias rau lub valve actuated kom ua raws li 25th tsab ntawm API 6D, tus actuator yuav tsum ua raws li API 6DX.
Qhov txawv ntawm API 6D thiab B 16 34 yog dab tsi?
ASME B16. 34: Muab cov txheej txheem kev ruaj ntseg zoo. API 6D: Kev tswj hwm kev tswj hwm nruj dua, suav nrog cov txheej txheem tshuaj xyuas thiab ntsuas tshwj xeeb.
Qhov txawv ntawm API 6D thiab API 594 yog dab tsi?
API 594 npog compact wafer thiab dual phaj check li qub, thaum API 6D npog cov raj xa dej nrog rau cov viav vias loj loj. Vim tias lawv cov hlab ntsha luv luv thiab lub caij nplooj ntoo hlav- pab kaw kom txo qis rov qab ntws tawm. Cracking siab yog feem ntau qis heev, feem ntau nyob ib ncig ntawm 0.05 txog 0.2 bar.
