I. Uhlolojikelele Lomkhiqizo
I-GB/T9948-2013ipayipi lensimbi engenamthungo liyipayipi lensimbi elingenamthungo eliphakeme elisetshenziselwa ikakhulukazi inqubo yokuqhekeka kwe-petroleum, futhi lisetshenziswa kabanzi emishinini ebalulekile njengamashubhu esithandweni somlilo, izinto ezishintsha ukushisa nokucindezela amapayipi ezindaweni zokuhluza uwoyela. Leli zinga lilawula ngokuqinile izinto ezibonakalayo, inqubo yokukhiqiza kanye nezidingo zokusebenza zamapayipi ensimbi ukuze kuqinisekiswe ukusebenza kwawo okuzinzile ezindaweni zokugqwala okuphezulu, izinga lokushisa eliphezulu kanye ne-high-pressure.
2. Izinto kanye nokusebenza
1. Izinto eziyinhloko
I-GB/T9948-2013amapayipi ensimbi angenamthungo enziwe ngezinto ezahlukahlukene ze-alloy ezisezingeni eliphakeme, kufaka phakathi:
Insimbi yesakhiwo se-Carbon:20G, 20MnG, 25MnG
I-alloy structural steel:15 MoG, 20 MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB
Insimbi engagqwali nensimbi engashisi: 1Cr18Ni9, 1Cr18Ni11Nb
2. Ukusebenza okubalulekile
Ukumelana nokushisa okuphezulu: Ifanele izinqubo zokushisa okuphezulu njengokuqhekeka kwe-petroleum (kufika ku-600 ° C noma ngaphezulu).
Ukumelana nokucindezela okuphezulu: Izinto ezinamandla aphezulu ziqinisekisa ukusebenza okuphephile kwamapayipi ngaphansi kwezindawo zokucindezela okukhulu.
Ukumelana nokugqwala: Izingxenye ze-alloy ezikhethekile zimelana ngempumelelo nemidiya egqwalayo njenge-hydrogen sulfide ne-carbon dioxide.
Ukuthembeka okuphezulu: Ukulawulwa kwekhwalithi okuqinile kuqinisekisa ukuthi izakhiwo zemishini nokwakheka kwamakhemikhali kwamapayipi ensimbi kuhlangabezana nezinga le-GB/T9948.
3. Inqubo yokukhiqiza
I-GB/T9948-2013 amapayipi ensimbi angenamthungo akhiqizwa ngokugoqa okushisayo kanye nomdwebo obandayo (ukugoqa):
Inqubo yokugoqa eshisayo: ishubhu eliyindilinga billet → ukushisa → ukubhobozwa → ukugoqa → ukusika → ukupholisa → ukuqondisa → ukuhlolwa kwekhwalithi → isitoreji.
Inqubo yokudweba okubandayo (ukugingqika): ukubhoboza → ukuchotshozwa → ukudweba okubandayo → ukwelashwa kokushisa → ukuqondisa → ukutholwa kwamaphutha → ukumaka → indawo yokugcina.
Zombili izinqubo ziqinisekisa ukunemba okuphezulu kwe-dimensional, indawo ebushelelezi kanye nezakhiwo ezinhle kakhulu zemishini yamapayipi ensimbi.
4. Izinkambu zokufaka isicelo
I-GB/T9948 petroleum cracking pipes isetshenziswa kabanzi ku:
Imboni ye-Petrochemical: iyunithi yokuqhekeka, i-hydrogenation reactor, imishini yokuguqula i-catalytic
Imboni yokucwenga uwoyela: amashubhu okushisa okushisa aphezulu, izishintshisi zokushisa, amapayipi anengcindezi ephezulu
Ukuthuthwa kwegesi yemvelo: ukumelana nokugqwala, amapayipi adlulisa igesi anomfutho ophezulu
Ukukhiqiza ama-boiler: ama-boilers esiteshini samandla, ama-industrial boiler pipeline systems
5. Amathemba emakethe
Ngokuthuthuka okusheshayo kwemboni ye-petrochemical yasekhaya kanye nokukhula kwesidingo semakethe yamazwe ngamazwe, umthamo wokuthengisa wamapayipi ensimbi angenamthungo we-GB/T9948 uyaqhubeka nokukhuphuka. Ukumelana kwayo okuhle kakhulu nezinga lokushisa eliphezulu nokumelana nokugqwala kuyenza ibe into ethandwayo yamapayipi emikhakheni yokuqhekeka nokucwengisiswa kwe-petroleum.
6. Izinyathelo zokuphepha zokuthenga nokusebenzisa
Ukukhetha izinto eziqinile: Khetha impahla efanele ye-GB/T9948 (efana ne-12CrMoG, 15CrMoG, njll.) ngokuvumelana nezimo zokusebenza (izinga lokushisa, ingcindezi, ukugqwala).
Isitifiketi sekhwalithi: Qinisekisa ukuthi ipayipi lensimbi lihlangabezana nezinga le-GB/T9948-2013 futhi linikeze umbiko wokuhlola wenkampani yangaphandle.
Ukufaka nokunakekela: Gwema ukulimala kwemishini ngesikhathi sokuthutha nokufakwa, futhi uhlole njalo ukugqwala kwamapayipi nezimo zengcindezi.
I-GB/T9948-2013 ipayipi yokuqhekeka kwe-petroleum isibe yisinqumo esifanelekile se-petrochemical, ukucwengisiswa, igesi yemvelo nezinye izimboni ngenxa yezinzuzo zayo zokumelana nokushisa okuphezulu, ukumelana nokucindezela okuphezulu nokumelana nokugqwala. Ukukhetha izinto ezifanele (ezifana ne-12CrMoG, 15CrMoG, njll.) kanye nokulandela ngokuqinile izindinganiso kungaqinisekisa ukusebenza okuphephile nokuzinzile kwepayipi lesikhathi eside.
