I. Chidule cha Zamalonda
GB/T9948-2013Chitoliro chachitsulo chosasunthika ndi chitoliro chachitsulo chosasunthika chapamwamba kwambiri chomwe chimagwiritsidwa ntchito makamaka pokonza mafuta, ndipo chimagwiritsidwa ntchito kwambiri pazida zazikulu monga machubu a uvuni, zosinthira kutentha ndi mapaipi opanikizika m'malo oyeretsera mafuta. Muyezo uwu umawongolera mosamala zinthu, njira zopangira ndi zofunikira pakugwira ntchito kwa mapaipi achitsulo kuti atsimikizire kuti amagwira ntchito bwino m'malo omwe ali ndi dzimbiri, kutentha kwambiri komanso kupanikizika kwambiri.
2. Zipangizo ndi magwiridwe antchito
1. Zipangizo zazikulu
GB/T9948-2013Mapaipi achitsulo chosasunthika amapangidwa ndi zipangizo zosiyanasiyana zapamwamba za alloy, kuphatikizapo:
Chitsulo chopangidwa ndi kaboni:20G, 20MnG, 25MnG
Chitsulo chopangidwa ndi aloyi:15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB
Chitsulo chosapanga dzimbiri komanso chitsulo chosagwira kutentha: 1Cr18Ni9, 1Cr18Ni11Nb
2. Kugwira ntchito kofunikira
Kukana kutentha kwambiri: Koyenera kugwiritsa ntchito kutentha kwambiri monga kusweka kwa mafuta (mpaka 600°C kapena kuposerapo).
Kukana kuthamanga kwambiri: Zipangizo zolimba kwambiri zimatsimikizira kuti mapaipi amagwira ntchito bwino m'malo omwe ali ndi kuthamanga kwambiri.
Kukana dzimbiri: Zigawo zapadera za aloyi zimalimbana bwino ndi zinthu zowononga monga hydrogen sulfide ndi carbon dioxide.
Kudalirika Kwambiri: Kuwongolera bwino khalidwe kumatsimikizira kuti mphamvu zamakina ndi kapangidwe ka mankhwala a mapaipi achitsulo zikukwaniritsa muyezo wa GB/T9948.
3. Njira zopangira
Mapaipi achitsulo opanda msoko a GB/T9948-2013 amapangidwa pogwiritsa ntchito kupondaponda kotentha ndi kuponda kozizira (kupondaponda):
Njira yotenthetsera yotentha: chubu chozungulira → kutentha → kuboola → kuzunguliza → kukula → kuziziritsa → kuwongola → kuyang'anira khalidwe → kusungira.
Njira yojambula mozizira (kuzungulira): kuboola → kusonkhanitsa → kujambula kozizira → kutentha → kuwongola → kuzindikira zolakwika → kulemba chizindikiro → kusungira.
Njira zonsezi zimatsimikizira kulondola kwakukulu, malo osalala komanso mphamvu zabwino kwambiri zamapaipi achitsulo.
4. Magawo ogwiritsira ntchito
Mapaipi odulira mafuta a GB/T9948 amagwiritsidwa ntchito kwambiri mu:
Makampani opanga mafuta: gawo losweka, hydrogenation reactor, zida zosinthira mphamvu
Makampani oyeretsera mafuta: machubu a ng'anjo yotentha kwambiri, zosinthira kutentha, mapaipi opanikizika kwambiri
Kuyendera gasi lachilengedwe: mapaipi otumizira gasi amphamvu komanso osagwira dzimbiri
Kupanga ma boiler: ma boiler a siteshoni yamagetsi, makina opangira mapaipi a boiler a mafakitale
5. Kuthekera kwa msika
Ndi chitukuko chachangu cha makampani opanga mafuta m'dziko muno komanso kukula kwa kufunikira kwa msika wapadziko lonse, kuchuluka kwa malonda a mapaipi achitsulo opanda zingwe a GB/T9948 kukupitirira kukwera. Kukana kwake kutentha kwambiri komanso kukana dzimbiri kumapangitsa kuti chitolirochi chikhale chodziwika bwino m'minda yopangira mafuta ophwanyika ndi kuyeretsa.
6. Malangizo Oyenera Kutsatira Pogula ndi Kugwiritsa Ntchito
Kusankha zinthu mokhwima: Sankhani zinthu zoyenera za GB/T9948 (monga 12CrMoG, 15CrMoG, ndi zina zotero) malinga ndi momwe zinthu zilili (kutentha, kuthamanga, kuwononga).
Satifiketi ya Ubwino: Onetsetsani kuti chitoliro chachitsulo chikukwaniritsa muyezo wa GB/T9948-2013 ndikupereka lipoti lowunikira la chipani chachitatu.
Kukhazikitsa ndi kukonza: Pewani kuwonongeka kwa makina panthawi yoyendetsa ndi kukhazikitsa, ndipo nthawi zonse yang'anani momwe mapaipi amakhalira ndi dzimbiri komanso momwe mpweya umayendera.
Chitoliro cha GB/T9948-2013 chophwanya mafuta chakhala chisankho chabwino kwambiri cha mafakitale a petrochemical, refinery, gasi wachilengedwe ndi mafakitale ena chifukwa cha ubwino wake wokana kutentha kwambiri, kukana kuthamanga kwambiri komanso kukana dzimbiri. Kusankha zinthu zoyenera (monga 12CrMoG, 15CrMoG, ndi zina zotero) ndikutsatira mosamala miyezo kungatsimikizire kuti payipiyo ikugwira ntchito bwino komanso mokhazikika kwa nthawi yayitali.
