Chitoliro chomata arc otchetcha cha API 5l mzere mapaipi

Kufotokozera kwaifupi:

Mu gawo la mafuta oyendetsa mafuta ndi mpweya, kugwiritsa ntchito matope ophatikizika a Arc kumayamba kwambiri, makamaka pomanga chipika cha API 5L. Chitoliro cha SSAW (chitoliro chambiri) chimadziwika) chimadziwika ndi mphamvu zake zazikulu, kukhazikika komanso kusinthasintha kofunikira pofuna kugwiritsa ntchito mafuta ngati mafuta ndi mpweya.

Matamba a malonda

AChithunzi cha API 5lMuyezo ndi gawo lopangidwa ndi American petroleum Institute (API) pazoyenda zamafuta achilengedwe, mafuta ndi madzi. Imafotokoza zofunikira zopanga ziphuphu zazitsulo zam'manja ndipo zimayika malangizo okhwimitsa bwino, mphamvu ndi magwiridwe ake.

Chitoliro cha SSAWImapangidwa pogwiritsa ntchito njira yoloza kukhazikika yomwe imaphatikizapo kupanga chitsulo cha chitsulo chozungulira kenako ndikugwiritsa ntchito arc yotentha kuti igwetse m'mbali mwa chipikacho.

Chimodzi mwazinthu zabwino kwambiri pogwiritsa ntchito chitoliro chazithunzithunzi cha Arc olima mu API 5l mzere mapaipi ndikutha kuthana ndi zovuta zazikulu komanso zakunja. Izi ndizofunikira kwambiri mu malonda ndi gasi, pomwe ma pipelines amawonekera kwambiri komanso katundu wolemera. Kupanga kwamphamvu kwa mapaipi a Ssaw kumapangitsa kuti zikhale bwino pamapaipoli omwe amagwiritsa ntchito zovuta zambiri komanso kutentha kwambiri, kupereka njira yodalirika komanso yothetsera njira yoyendera ndalama zofunikira.

Kuphatikiza apo, kusinthasintha kwa spormer yolumikizira kwa Arc yolumikizidwa kumapangitsa kuti ikhale yosavuta kukhazikitsa ndikusankha ndalama zowononga pamapaipi. Kutha kwawo kusintha masinthidwe am'madzi kumathetsa kufunika kwa kupanga kokwera ndi nthawi yopanga ndikuchepetsa chiopsezo cha kutayikira ndi kulephera. Kuphatikiza apo, mkati mwamkati mwa mapaipi a Ssaw amachepetsa mikangano ndi chipwirikiti, zomwe zimapangitsa kuti mphamvu zambiri ziziyenda bwino.

Mwachidule, kugwiritsa ntchito chitoliro chazithunzithunzi cha arc cha api 5l mzere chitoliro zomwe zimapangitsa kuti kukhala njira yokongola yopanga mafuta ndi gasi. Mphamvu zawo, kulimba komanso kusinthasintha kumapangitsa kuti akhale abwino kuti agwiritse ntchito malo ogwiritsira ntchito, pomwe kukhazikika kwawo kwakhazikitsidwa ndi njira yochepetsera kumapereka njira yothandizira pomanga nkhuni. Monga momwe akufunira zodalirika, mpweya wabwino wamafuta, mpweya wachilengedwe ndi madzi zikupitilirabe, kufunikira kwa chitoliro chomata kwambiri mu Arc mzere wa API 5L sichingafanane. Ndi ntchito yake yotsimikizika ndi kusiyanasiyana,Chitoliro cha mapiri a Arcyakhazikitsidwa kuti ikhale yovuta kwambiri yazachipatala yomwe imayendetsa chuma padziko lonse lapansi.
