Isingeniso kumapayipi ensimbi angenamthungo ensimbi yesakhiwo sekhabhoni esezingeni eliphezulu kanye nensimbi yesakhiwo se-alloy yamapayipi ebhoyila enomfutho ophezulu nangaphezulu

GB/T5310Amapayipi ensimbi angenamthungo ajwayelekile ayimikhiqizo esezingeni eliphezulu eyenzelwe amapayipi ebhoyila anomfutho ophezulu nangaphezulu. Enziwe ngezinto zensimbi ezakhiwe ngekhabhoni kanye nensimbi ezakhiwe nge-alloy ukuqinisekisa ukusebenza kwawo okuhle kakhulu kanye nokuthembeka ezindaweni ezinokushisa okuphezulu kanye nomfutho ophezulu. Le payipi yensimbi engenamthungo isetshenziswa kabanzi ekwakhiweni kwamapayipi ebhoyila kanye nezishintshi zokushisa, okunikeza isiqinisekiso esiqinile sokukhiqiza kwezimboni.

Amabanga ayinhloko

GB/T5310Amapayipi ensimbi ajwayelekile angenamthungo enziwe kakhulu nge-Cr-Mo alloy kanye ne-Mn alloy, kanti amazinga ayinhloko afaka phakathi20G, 20Mg, 20MoG, 12CrMoG, njll. Lezi zinto zinamandla aphezulu okushisa okuphezulu kanye nokumelana nokushiswa kwe-oxidation, futhi zingasetshenziswa isikhathi eside ezindaweni zokusebenza ezinzima ngaphandle kokwehluleka. Phakathi kwazo:

20G: Insimbi yesakhiwo sekhabhoni esezingeni eliphezulu enobulukhuni obuhle kanye nokuqina, evame ukusetshenziswa kumapayipi ebhoyila anomfutho ophakathi nendawo kanye nophansi.
20Mg: Ukwengeza i-manganese ku-20G kuthuthukisa kakhulu amandla nokuqina kwezinto, okulungele amapayipi ebhoyila anomfutho ophakathi nendawo kanye nowezinga eliphezulu.
20MoG: I-Molybdenum yengezwa ku-20G, okuthuthukisa kakhulu ukumelana nokushisa kanye nokumelana nokukhukhuleka, futhi ifaneleka kumapayipi ebhoyila anomfutho ophezulu.
12CrMoG: Insimbi eyakhiwe nge-alloy equkethe i-chromium ne-molybdenum, enokumelana okuhle kakhulu nokushiswa kokushisa okuphezulu kanye namandla okushisa aphezulu, efanelekile kumapayipi ebhoyila anomfutho ophezulu kakhulu.
Amamaki ensimbi yesakhiwo se-alloy

Amazinga ensimbi ahlanganisiwe enziwe nge-GB/T5310 ajwayelekile ahlanganisa ne-15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, njll. Lawa mazinga amapayipi ensimbi anezakhiwo ezahlukene zemishini kanye nobubanzi obufanele ngokuya ngezinhlobo ezahlukene zamakhemikhali kanye nezinqubo zokwelapha ukushisa:

15MoG kanye no-20MoG: Ukwengezwa kwenani elifanele le-molybdenum kuthuthukisa kakhulu amandla okushisa aphezulu kanye nokumelana nokugqwala kwepayipi lensimbi.
12CrMoG kanye15CrMoG: Ukwengezwa kwe-chromium ne-molybdenum kuthuthukisa ukumelana nokushiswa kwe-oxidation kanye namandla okushisa aphezulu epayipi lensimbi, futhi kufanelekile ezindaweni ezinamazinga okushisa aphezulu kanye nokucindezela.
I-12Cr2MoG kanye ne-12CrMoVG: Ukwakheka kwe-alloy kuphinde kuthuthukiswe, kokubili ngamandla okushisa aphezulu kanye nokumelana ne-oxidation, futhi kusebenza kahle kakhulu ezindaweni ezibucayi.
Izicelo
Amapayipi ensimbi angenamthungo ajwayelekile e-GB/T5310 asetshenziswa kabanzi kumapayipi e-boiler kanye nama-heat exchanger, ikakhulukazi emishinini yokushisa ephezulu kanye nengcindezi ephezulu njengama-boiler esiteshi sikagesi, ama-boiler ezimboni, kanye nama-waste heat boilers. Lawa mapayipi ensimbi angenamthungo angamelana nokucindezeleka okuphezulu kakhulu kokusebenza kanye namazinga okushisa, okuqinisekisa ukusebenza kahle kanye nokuphila isikhathi eside kwama-boiler kanye nama-heat exchanger. Ngaphezu kwalokho, lawa mapayipi ensimbi asetshenziswa nasemishinini yokushintshanisa ukushisa embonini ye-petrochemical, okwandisa izindawo zawo zokusetshenziswa.
Isifinyezo
Amapayipi ensimbi angenamthungo ajwayelekile e-GB/T5310 abe ngumkhiqizo okhethwayo wamapayipi ebhoyila anomfutho ophezulu nangaphezulu ngenxa yezakhiwo zawo ezinhle kakhulu kanye nobubanzi bezicelo. Kungakhathaliseki ukuthi angama-20G, 20Mg, 20MoG, 12CrMoG nezinye izinto, noma ama-15MoG, 20MoG, 12CrMoG kanye nezinye izinhlobo zensimbi ezakhiwe nge-alloy, wonke abonisa ukumelana okuhle kakhulu nokushiswa kokushisa okuphezulu kanye namandla okushisa aphezulu, enikeza iziqinisekiso ezithembekile zokusebenza okuphephile nokusebenza kahle kwemishini yezimboni.
