I. Isishwankathelo seMveliso
GB/T9948-2013umbhobho wensimbi ongenamthungo ngumbhobho wensimbi ongenamthungo okumgangatho ophezulu osetyenziselwa ngokukodwa inkqubo yokuqhawula i-petroleum, kwaye isetyenziswa ngokubanzi kwizixhobo eziphambili ezifana neetyhubhu zesithando somlilo, ukutshintshiselana kobushushu kunye nemibhobho yoxinzelelo kwiindawo zokucoca ioli. Lo mgangatho ulawula ngokungqongqo izinto eziphathekayo, inkqubo yokuvelisa kunye neemfuno zokusebenza kweemibhobho zetsimbi ukuze kuqinisekiswe ukusebenza kwazo okuzinzile kwi-corrosion ephezulu, ukushisa okuphezulu kunye noxinzelelo oluphezulu.
2. Izinto eziphathekayo kunye nokusebenza
1. Izinto eziphambili
GB/T9948-2013imibhobho yentsimbi engenamthungo yenziwe ngezinto ezahlukeneyo ezikumgangatho ophezulu we-alloy, kubandakanywa:
Intsimbi yolwakhiwo lwekhabhoni:20G, 20MnG, 25MnG
Ingxubevange yentsimbi yesakhiwo:15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB
Intsimbi engatyiwayo kunye nentsimbi ekwaziyo ukumelana nobushushu: 1Cr18Ni9, 1Cr18Ni11Nb
2. Ukusebenza okungundoqo
Ukumelana nokushisa okuphezulu: Kufanelekile kwiinkqubo eziphezulu zokushisa ezifana nokuqhekeka kwepetroleum (ukuya kwi-600 ° C okanye ngaphezulu).
Ukumelana noxinzelelo oluphezulu: Izinto eziphezulu zokuqina ziqinisekisa ukusebenza ngokukhuselekileyo kwemibhobho phantsi koxinzelelo oluphezulu.
Ukumelana nokubola: Amacandelo e-alloy akhethekileyo axhathisa ngokufanelekileyo imidiya ephazamisayo efana ne-hydrogen sulfide kunye ne-carbon dioxide.
Ukuthembeka okuphezulu: Ukulawulwa komgangatho ongqongqo kuqinisekisa ukuba iipropati zomatshini kunye nokwakhiwa kweekhemikhali zemibhobho yensimbi ihlangabezana nomgangatho we-GB / T9948.
3. Inkqubo yokuvelisa
I-GB/T9948-2013 imibhobho yentsimbi engenamthungo iveliswa ngokuqengqeleka okushushu kunye nomzobo obandayo (ukuqengqeleka):
Inkqubo yokuqengqeleka eshushu: ibhilethi yetyhubhu engqukuva → ukufudumeza → ukugqobhoza → ukuqengqeleka → ukupholisa → ukupholisa → ukulungisa → ukuhlola umgangatho → ugcino.
Umzobo obandayo (ukuqengqeleka) inkqubo: ukugqobhoza → ukuchola → umzobo obandayo → ukunyanga ubushushu → ukulungisa → ukubona isiphene → ukuphawula → ukugcina.
Zombini iinkqubo ziqinisekisa ukuchaneka komgangatho ophezulu, indawo egudileyo kunye neempawu ezigqwesileyo zomatshini wemibhobho yentsimbi.
4. Iinkalo zesicelo
Imibhobho yokuqhekeka ye-GB/T9948 yepetroleum isetyenziswa kakhulu apha:
Umzi-mveliso wePetrochemical: iyunithi yokuqhekeka, i-hydrogenation reactor, izixhobo zokuguqula izinto
Ishishini lokucoca i-oyile: iityhubhu zobushushu obuphezulu, abatshintshisi bobushushu, imibhobho yoxinzelelo oluphezulu
Ukuthuthwa kwerhasi yendalo: i-corrosion-resistant, i-high-pressure transmission pipelines
Ukwenziwa kwebhoyila: iibhoyila zesikhululo samandla, iinkqubo zebhoyila yeshishini
5. Amathemba emarike
Ngophuhliso olukhawulezayo lweshishini lepetrochemical yasekhaya kunye nokukhula kwemfuno yeemarike zamazwe ngamazwe, umthamo wokuthengisa we-GB/T9948 wemibhobho yentsimbi engenamthungo uyaqhubeka nokunyuka. Ukumelana kwayo nobushushu obuphezulu obuphezulu kunye nokumelana nokubola kwenza kube yinto ekhethiweyo yombhobho kwiindawo zokuqhekeka kwepetroleum kunye nokucocwa.
6. Izilumkiso zokuthenga nokusetyenziswa
Ukukhethwa kwezinto ezingqongqo: Khetha izinto ezifanelekileyo ze-GB / T9948 (ezifana ne-12CrMoG, 15CrMoG, njl.) Ngokweemeko zokusebenza (ubushushu, uxinzelelo, ukubola).
Ukuqinisekiswa komgangatho: Qinisekisa ukuba umbhobho wensimbi udibana nomgangatho we-GB / T9948-2013 kwaye unike ingxelo yokuhlola umntu wesithathu.
Ukufakela kunye nokugcinwa: Gwema umonakalo womatshini ngexesha lokuthutha kunye nokufakwa, kwaye ukhangele rhoqo ukubola kwemibhobho kunye neemeko zoxinzelelo.
I-GB / T9948-2013 ipayipi yokuqhaqha i-petroleum ibe yinto efanelekileyo yokukhetha i-petrochemical, ukucocwa, igesi yendalo kunye namanye amashishini ngenxa yeenzuzo zayo zokuchasana nokushisa okuphezulu, ukunyanzeliswa koxinzelelo oluphezulu kunye nokuxhatshazwa kwe-corrosion. Ukukhetha izinto ezifanelekileyo (ezifana ne-12CrMoG, 15CrMoG, njl.) kunye nokulandela ngokungqongqo imigangatho kunokuqinisekisa ukusebenza okukhuselekileyo kunye nokuzinzileyo kwexesha elide lombhobho.
