I. Ukubuka Konke Komkhiqizo
GB/T9948-2013ipayipi lensimbi elingenamthungo liyipayipi lensimbi elingenamthungo elisezingeni eliphezulu elisetshenziselwa inqubo yokuqhekeka kwephethiloli, futhi lisetshenziswa kabanzi emishinini ebalulekile efana namapayipi esithando, ama-heat exchanger kanye namapayipi okucindezela ezindaweni zokuhlanza uwoyela. Leli zinga lilawula ngokuqinile izinto zokwakha, inqubo yokukhiqiza kanye nezidingo zokusebenza kwamapayipi ensimbi ukuqinisekisa ukusebenza kwawo okuzinzile ezindaweni ezinokugqwala okuphezulu, izinga lokushisa eliphezulu kanye nezinga lokucindezela okuphezulu.
2. Izinto zokwakha kanye nokusebenza
1. Izinto eziyinhloko
GB/T9948-2013Amapayipi ensimbi angenamthungo enziwe ngezinto ezahlukahlukene ze-alloy ezisezingeni eliphezulu, okuhlanganisa:
Insimbi yesakhiwo sekhabhoni:20G, 20MnG, 25MnG
Insimbi yesakhiwo se-alloy:15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB
Insimbi engagqwali kanye nensimbi engashisi: 1Cr18Ni9, 1Cr18Ni11Nb
2. Ukusebenza okuyinhloko
Ukumelana nokushisa okuphezulu: Kufanelekela izinqubo zokushisa okuphezulu njengokuqhekeka kwephethiloli (kufika ku-600°C noma ngaphezulu).
Ukumelana nomfutho ophezulu: Izinto eziqinile ziqinisekisa ukusebenza okuphephile kwamapayipi ngaphansi kwezimo zomfutho ophezulu.
Ukumelana nokugqwala: Izingxenye ezikhethekile ze-alloy zimelana ngempumelelo nemithombo egqwalisayo njenge-hydrogen sulfide kanye ne-carbon dioxide.
Ukuthembeka okuphezulu: Ukulawulwa kwekhwalithi okuqinile kuqinisekisa ukuthi izakhiwo zemishini kanye nokwakheka kwamakhemikhali kwamapayipi ensimbi kuhlangabezana nezindinganiso ze-GB/T9948.
3. Inqubo yokukhiqiza
Amapayipi ensimbi angenamthungo e-GB/T9948-2013 akhiqizwa ngokugoqa okushisayo kanye nokudonsa okubandayo (ukugoqa):
Inqubo yokugoqa eshisayo: ishubhu eliyindilinga → ukushisa → ukubhoboza → ukugoqa → usayizi → ukupholisa → ukuqondisa → ukuhlolwa kwekhwalithi → isitoreji.
Inqubo yokudweba okubandayo (ukugoqa): ukubhoboza → ukukhahlela → ukudweba okubandayo → ukwelashwa kokushisa → ukuqondisa → ukutholwa kwamaphutha → ukumaka → isitoreji.
Zombili lezi zinqubo ziqinisekisa ukunemba okuphezulu, indawo ebushelelezi kanye nezakhiwo ezinhle kakhulu zemishini yamapayipi ensimbi.
4. Izinkambu zohlelo lokusebenza
Amapayipi okuqhekeka uphethiloli e-GB/T9948 asetshenziswa kabanzi ku:
Imboni ye-Petrochemical: iyunithi yokuqhekeka, i-hydrogenation reactor, imishini yokuguqula i-catalytic
Imboni yokucwenga uwoyela: amashubhu esithando sokushisa okuphezulu, ama-heat exchanger, amapayipi anomfutho ophezulu
Ukuthuthwa kwegesi yemvelo: amapayipi okudlulisa igesi angagqwali futhi anomfutho ophezulu
Ukukhiqizwa kwebhoyila: amabhoyila esiteshi sikagesi, izinhlelo zamapayipi ebhoyila ezimboni
5. Amathemba emakethe
Ngokuthuthuka okusheshayo kwemboni yamakhemikhali kaphethiloli yasekhaya kanye nokukhula kwesidingo semakethe yamazwe ngamazwe, inani lokuthengisa lamapayipi ensimbi angenamthungo e-GB/T9948 liyaqhubeka nokwenyuka. Ukumelana kwayo nokushisa okuphezulu okuhle kakhulu kanye nokumelana nokugqwala kwenza kube yipayipi elithandwayo emikhakheni yokuqhekeka nokuhluzwa kukaphethiloli.
6. Izinyathelo zokuphepha zokuthenga nokusebenzisa
Ukukhetha izinto eziqinile: Khetha izinto ezifanele ze-GB/T9948 (njenge-12CrMoG, 15CrMoG, njll.) ngokuya ngezimo zokusebenza (izinga lokushisa, ingcindezi, ukugqwala).
Isitifiketi sekhwalithi: Qinisekisa ukuthi ipayipi lensimbi lihlangabezana nezindinganiso ze-GB/T9948-2013 futhi unikeze umbiko wokuhlola womuntu wesithathu.
Ukufakwa nokugcinwa: Gwema umonakalo wemishini ngesikhathi sokuthutha nokufakwa, futhi uhlole njalo ukugqwala kwepayipi kanye nezimo zokucindezela.
Ipayipi lokuqhekeka likaphethiloli le-GB/T9948-2013 seliyisinqumo esifanele samakhemikhali kaphethiloli, ukucwenga, igesi yemvelo kanye neminye imboni ngenxa yezinzuzo zalo zokumelana nokushisa okuphezulu, ukumelana nokucindezela okuphezulu kanye nokumelana nokugqwala. Ukukhetha izinto ezifanele (njenge-12CrMoG, 15CrMoG, njll.) nokulandela ngokuqinile amazinga kungaqinisekisa ukusebenza okuphephile nokuzinzile kwesikhathi eside kwepayipi.
