Isingeniso sensimbi yesakhiwo sekhabhoni yekhwalithi ephezulu kanye nensimbi yamapayipi ensimbi engenamthungo esezingeni eliphezulu nangaphezulu kwamapayipi okubhayela isitimu.

I-GB/T5310amapayipi ensimbi angenamthungo ajwayelekile ayimikhiqizo yekhwalithi ephezulu eklanyelwe ukucindezela okukhulu nangaphezulu kwamapayipi okubhayela isitimu. Zenziwe ngensimbi yekhwalithi ephezulu ye-carbon structural kanye ne-alloy structural steel materials ukuze kuqinisekiswe ukusebenza kwazo okuhle kakhulu nokuthembeka endaweni yokushisa ephezulu kanye nengcindezi ephezulu. Leli payipi lensimbi elingenamthungo lisetshenziswa kabanzi ekwenzeni amapayipi okubhayela kanye nokushintshanisa ukushisa, okuhlinzeka ngesiqinisekiso esiqinile sokukhiqizwa kwezimboni.

Amabanga amakhulu

I-GB/T5310amapayipi ensimbi angenamthungo ajwayelekile enziwa ikakhulukazi nge-Cr-Mo alloy ne-Mn alloy, futhi amamaki amakhulu ahlanganisa20G, 20Mg, 20MoG, 12CrMoG, njll Lezi zinto zinamandla amahle kakhulu okushisa aphezulu kanye nokumelana ne-oxidation, futhi zingasetshenziswa isikhathi eside ezindaweni zokusebenza ezinzima ngaphandle kokwehluleka. Phakathi kwazo:

20G: Insimbi yesakhiwo sekhabhoni yekhwalithi ephezulu enepulasitiki enhle nokuqina, evamise ukusetshenziswa kumapayipi okubhayela okucindezela okuphakathi nendawo naphansi.
I-20Mg: Ukwengeza i-manganese ku-20G kuthuthukisa futhi amandla nobulukhuni bento, ifanele amapayipi okubhayela aphakathi nendawo naphezulu.
I-20MoG: I-Molybdenum yengezwe ku-20G, ethuthukisa kakhulu ukumelana nokushisa nokumelana nokukhuphuka, futhi ifanele amapayipi okushisa aphezulu.
12CrMoG: Insimbi yesakhiwo se-alloy equkethe i-chromium ne-molybdenum, enokumelana ne-oxidation ephezulu kakhulu yezinga lokushisa eliphezulu namandla ezinga lokushisa eliphezulu, ifanele amapayipi okubhayela we-ultra-high-high-pressure.
Ingxubevange amamaki ensimbi yesakhiwo

Amabanga ensimbi yesakhiwo sengxubevange yamapayipi ensimbi angenamthungo ajwayelekile e-GB/T5310 ahlanganisa futhi i-15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, njll. Lawa mabanga amapayipi ensimbi anezakhiwo ezihlukene zemishini kanye nobubanzi obusebenzayo ngokuya ngezinqubo ezahlukene zokwelashwa kwamakhemikhali nokushisa. :

I-15MoG ne-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 ne-oxidation namandla okushisa aphezulu wepayipi yensimbi, futhi ifanele indawo enamazinga okushisa aphezulu nezingcindezi.
I-12Cr2MoG ne-12CrMoVG: Ukwakheka kwe-alloy kuthuthukiswa futhi, ngakho kokubili izinga lokushisa eliphezulu nokumelana ne-oxidation, futhi kusebenza kahle ikakhulukazi ezindaweni ezibucayi.
Izinhlelo zokusebenza
Amapayipi ensimbi angenamthungo e-GB/T5310 asetshenziswa kakhulu kumapayipi okubhayela nasezishintshisani zokushisa, ikakhulukazi endaweni yokushisa ephezulu kanye nemishini yokucindezela okukhulu njengama-boilers esiteshini samandla, ama-boilers ezimbonini, nama-boilers okushisa okulahlwayo. Lawa mapayipi ensimbi angenamthungo angakwazi ukumelana nezingcindezi eziphakeme kakhulu zokusebenza namazinga okushisa, aqinisekise ukusebenza kahle nempilo ende yama-boilers kanye nezishintshisi zokushisa. Ngaphezu kwalokho, lawa mapayipi ensimbi nawo asetshenziswa emishinini yokushintshanisa ukushisa embonini ye-petrochemical, ngokuqhubekayo andisa izindawo zabo zokufaka isicelo.
Isifinyezo
Amapayipi ensimbi angenamthungo e-GB/T5310 asephenduke umkhiqizo okhethwayo wokucindezela okukhulu nangaphezulu kwamapayipi okubhayela ngesitimu ngenxa yezakhiwo zawo ezibonakalayo ezinhle kakhulu kanye nobubanzi bezinhlelo zokusebenza. Noma ngabe i-20G, 20Mg, 20MoG, 12CrMoG nezinye izinto, noma i-15MoG, 20MoG, 12CrMoG kanye namanye amamaki ensimbi ye-alloy, zonke zibonisa ukumelana nokushisa okuphezulu kwe-oxidation namandla okushisa aphezulu, zinikeza iziqinisekiso ezithembekile zokusebenza okuphephile nokusebenza kahle kwe-alloy. imishini yezimboni.
