I. Chidule cha Zamalonda
GB/T9948-2013Chitoliro chachitsulo chosasunthika ndi chitoliro chachitsulo chamtengo wapatali chomwe chimagwiritsidwa ntchito makamaka pophwanya mafuta a petroleum, ndipo chimagwiritsidwa ntchito kwambiri pazida zazikulu monga machubu ang'anjo, osinthanitsa kutentha ndi mapaipi oponderezedwa m'malo opangira mafuta. Muyezo uwu umayendetsa mosamalitsa zinthu, njira zopangira ndi zofunikira za ntchito zamapaipi achitsulo kuti zitsimikizire kuti zimagwira ntchito mokhazikika m'malo okwera kwambiri, kutentha kwambiri komanso kupanikizika kwambiri.
2. Zida ndi ntchito
1. Zida zazikulu
GB/T9948-2013mapaipi achitsulo osasunthika amapangidwa ndi zinthu zosiyanasiyana zapamwamba za aloyi, kuphatikiza:
Carbon structural steel:20G pa, 20MnG, 25MnG
Aloyi structural chitsulo:15Mg, 20 mog, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB
Chitsulo chosapanga dzimbiri ndi chitsulo chosagwira kutentha: 1Cr18Ni9, 1Cr18Ni11Nb
2. Ntchito yaikulu
Kukana kutentha kwakukulu: Koyenera kutentha kwambiri monga kuphulika kwa petroleum (mpaka 600 ° C kapena kuposa).
Kukaniza kuthamanga kwambiri: Zida zamphamvu kwambiri zimatsimikizira kuti mapaipi akugwira ntchito motetezeka m'malo opanikizika kwambiri.
Kukana dzimbiri: Zida zapadera za alloy zimalimbana bwino ndi zinthu zowononga monga hydrogen sulfide ndi carbon dioxide.
Kudalirika kwakukulu: Kuwongolera kokhazikika kumawonetsetsa kuti makina ndi kapangidwe kake ka mapaipi achitsulo amakwaniritsa muyezo wa GB/T9948.
3. Njira yopanga
GB/T9948-2013 mapaipi achitsulo opanda msoko amapangidwa ndi kujambula kotentha komanso kozizira (kugudubuza):
Njira yozungulira yotentha: chubu chozungulira → kutenthetsa → kubowoleza → kugudubuza → kuzizira → kuzizira → kuwongola → kuyang'anira khalidwe → kusunga.
Kujambula kozizira (kugudubuza): kubowola → pickling → kujambula ozizira → kutentha kutentha → kuwongola → kuzindikira zolakwika → kulemba chizindikiro → kusunga.
Onse njira kuonetsetsa mkulu dimensional molondola, yosalala pamwamba ndi kwambiri mawotchi zimatha zitsulo mipope.
4. Minda yofunsira
GB/T9948 mafuta osokoneza mapaipi amagwiritsidwa ntchito kwambiri mu:
Makampani a petrochemical: gawo losweka, hydrogenation reactor, zida zosinthira
Makampani oyenga mafuta: machubu ang'anjo otentha kwambiri, osinthanitsa kutentha, mapaipi apamwamba kwambiri
Mayendetsedwe a gasi wachilengedwe: osachita dzimbiri, mapaipi opatsira mpweya wothamanga kwambiri
Kupanga ma boiler: ma boiler opangira magetsi, makina opangira mapaipi opangira mafakitale
5. Zoyembekeza zamsika
Ndikukula kwachangu kwamakampani amafuta am'nyumba komanso kukula kwa msika wapadziko lonse lapansi, kuchuluka kwa malonda a mapaipi achitsulo a GB/T9948 opanda zitsulo akupitilira kukwera. Kukaniza kwake kutentha kwambiri komanso kukana kwa dzimbiri kumapangitsa kuti chitoliro chake chikhale chokonda kwambiri m'minda yamafuta osweka ndi kuyenga.
6. Kusamala pogula ndi kugwiritsa ntchito
Kusankha zinthu mwamphamvu: Sankhani zinthu zoyenera za GB/T9948 (monga 12CrMoG, 15CrMoG, etc.) malinga ndi momwe ntchito ikugwirira ntchito (kutentha, kupanikizika, corrosiveness).
Chitsimikizo cha Ubwino: Onetsetsani kuti chitoliro chachitsulo chikugwirizana ndi muyezo wa GB/T9948-2013 ndikupereka lipoti loyendera lachitatu.
Kuyika ndi kukonza: Pewani kuwonongeka kwa makina panthawi yoyendetsa ndi kukhazikitsa, ndipo nthawi zonse muziyang'ana dzimbiri la mapaipi ndi kupanikizika.
GB/T9948-2013 mafuta osokoneza chitoliro chakhala chisankho chabwino kwa petrochemical, kuyenga, gasi lachilengedwe ndi mafakitale ena chifukwa cha ubwino wake wotsutsa kutentha, kuthamanga kwamphamvu ndi kukana kwa dzimbiri. Kusankha zinthu zoyenera (monga 12CrMoG, 15CrMoG, etc.) ndi kutsatira mosamalitsa miyezo kungatsimikizire kuti payipi ikugwira ntchito motetezeka komanso yokhazikika kwa nthawi yayitali.
