Kodi NACE MR0175 ndi chiyani?

NACE MR0175, yomwe imadziwikanso kuti "Standard Material Requirements for Resistance to Sulfide Stress Cracking in Corrosive Petroleum Refining Environments," ndi muyezo womwe unapangidwa ndi National Association of Corrosion Engineers (NACE) kuti athetse vuto la kusweka kwa sulfide m'mafuta ndi mafuta. makampani gasi. Muyezo uwu umapereka zitsogozo pakusankha ndi kuyenerera kwa zinthu zomwe zimagwiritsidwa ntchito pazida ndi zigawo zomwe zidzawonekere kumalo owononga poyeretsa mafuta.

Sulfide stress cracking (SSC) ndi mtundu wa hydrogen-induced cracking yomwe imapezeka muzitsulo ndi ma alloys ena pamene akukumana ndi hydrogen sulfide (H2S) ndi kupsinjika maganizo. Kusweka kotereku kungayambitse kulephera kwa zida komanso kuyika chiwopsezo chachikulu chachitetezo ndi chilengedwe poyenga mafuta. NACE MR0175 idapangidwa kuti ichepetse chiwopsezo cha SSC popereka zofunikira pakusankhidwa ndi kuyenerera kwa zida zomwe zimalimbana ndi kupsinjika kwa sulfide.

Muyezowu umakhudza zinthu zosiyanasiyana, kuphatikizapo zitsulo za carbon ndi low-alloy, zitsulo zosapanga dzimbiri, ma aloyi a faifi tambala, ndi ma aloyi ena osagwirizana ndi dzimbiri. Amapereka malangizo osankha zinthu, chithandizo cha kutentha, malire a kuuma, ndi zofunikira zoyezetsa kuti zitsimikizidwe kuti zipangizo zomwe zimagwiritsidwa ntchito poyeretsa mafuta zimagonjetsedwa ndi kupsinjika kwa sulfide.

Chimodzi mwazinthu zofunika kwambiri za NACE MR0175 ndikuyenerera kwa zida kudzera pakuyesa ndi zolemba. Muyezowu umafotokoza zofunikira zoyezetsa, monga kuyezetsa kuuma, kuyezetsa kolimba, komanso kuyesa kusweka kwa sulfide, kuwonetsa kukana kwa zida kusweka kwa kupsinjika kwa sulfide. Kuphatikiza apo, muyezowo umafuna kuti opanga apereke zolemba, monga malipoti oyesa zinthu ndi ziphaso zotsatiridwa, kuti atsimikizire kuti zidazo zikukwaniritsa zofunikira za NACE MR0175.

NACE MR0175 imaperekanso zitsogozo zopangira ndi kupanga zida ndi zida zochepetsera chiopsezo cha kupsinjika kwa sulfide. Izi zikuphatikizanso malingaliro a njira zowotcherera, zochizira pamwamba, ndi njira zina zopewera kusweka kwa hydrogen m'munda.

Kutsatira NACE MR0175 ndikofunikira pakuwonetsetsa kukhulupirika ndi kudalirika kwa zida ndi zida zomwe zimagwiritsidwa ntchito poyenga mafuta. Posankha ndi kuyenerera zipangizo malinga ndi muyezo, ogwira ntchito angathe kuchepetsa chiopsezo cha sulfide stress ang'onoang'ono ndi kuonetsetsa chitetezo ndi mphamvu ya malo awo.

Pomaliza, NACE MR0175 ndi muyezo wofunikira kwambiri pamakampani amafuta ndi gasi, omwe amapereka malangizo pakusankha ndi kuyenerera kwazinthu zomwe zimalimbana ndi kupsinjika kwa sulfide m'malo oyenga mafuta. Potsatira zofunikira za muyezo uwu, ogwira ntchito angathe kuchepetsa chiopsezo cha kupsinjika kwa sulfide ndikuwonetsetsa kukhulupirika ndi kudalirika kwa zipangizo zawo ndi zigawo zake. Kutsatira NACE MR0175 ndikofunikira kuti pakhale chitetezo komanso magwiridwe antchito oyenga mafuta.
