20 #Q355B nezinye izisetshenziswa zikamanyolo ezinomfutho ophezulu wepayipi elingenamthungo

Incazelo emfushane:

Ipayipi elikhethekile likamanyolo i-GB6479-2000 libhekisela epayipini lensimbi elingenamthungo lemishini yomanyolo enomfutho ophezulu.Isetshenziselwa kakhulu ukudlulisa izinga lokushisa eliphezulu kanye namapayipi oketshezi olunomfutho ophezulu kumishini kamanyolo.Izinto ezimele ziyi-20, 16Mn, 12CrMo, 12Cr2Mo, njll.

Isingeniso somkhiqizo

Amapayipi ensimbi omanyolo wamakhemikhali asetshenziswa ikakhulukazi ukwenza insimbi yesakhiwo sekhabhoni ephezulu, insimbi yesakhiwo esiyingxubevange kanye nensimbi engagqwali engashisi nomfutho ophezulu wamapayipi obhayela anomfutho omkhulu nangaphezulu kwamashubhu futhi lawa mashubhu abhayela asebenza ngaphansi kwezinga lokushisa eliphezulu. kanye nomfutho ophezulu, futhi amashubhu azofakwa i-oxidized futhi agqwale ngaphansi kwesenzo segesi yokushisa ephezulu yokushisa kanye ne-steam.Ngakho-ke, amashubhu ensimbi adingeka ukuthi abe namandla ahlala njalo, ukumelana ne-oxidation ephezulu, nokuzinza okuhle kwenhlangano.Amamaki ensimbi asetshenzisiwe yilawa: amamaki ensimbi yekhwalithi ephezulu ye-carbon 20G, 20MnG, 25MnG;I-alloy structural steel amabanga 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, njll;Amashubhu kabhayela we-1Cr18Ni9 kanye ne-1Cr18Ni11Nb ajwayelekile enziwe ngensimbi egqwalile futhi engashisi azoba ngaphansi kokuhlolwa kwe-hydrostatic, ukuvutha kanye nokuhlolwa kokucaba ngakunye ngaphezu kokuqinisekisa ukwakheka kwamakhemikhali nezici zokuwumshini.Amashubhu ensimbi akhethekile omanyolo wamakhemikhali azolethwa esimweni sokwelashwa kokushisa.

Indawo esebenzayo

Ipayipi elikhethekile lomanyolo (i-GB6479-2000) iyinsimbi yensimbi yekhwalithi ephezulu ye-carbon structural kanye ne-alloy steel nekhono lensimbi ipayipi elifanele imishini yamakhemikhali namapayipi anokushisa okusebenzayo - 40 ~ 400 ℃ nokucindezela kokusebenza kwe-10 ~ 30Ma.

Ipayipi le-high pressure alloy lemishini kamanyolo (i-GB6479-2000) iyinsimbi esezingeni eliphakeme ye-carbon structural steel ne-alloy steel nekhono lensimbi ipayipi elifanele imishini yamakhemikhali namapayipi anokushisa okusebenzayo - 40 ~ 400 ℃ kanye nengcindezi yokusebenza engu-10 ~ 30Ma.

Isingeniso sokukhiqiza

(1) Indlela yokukhiqiza:

① Izinga lokushisa elisetshenziswayo lamapayipi ensimbi omanyolo lingaphansi kuka-450 ℃, futhi amapayipi asekhaya enziwa ikakhulukazi ngamapayipi ensimbi agoqwe ashisayo noma abandayo angu-10 # kanye no-20 #.

②Ipayipi lensimbi elikhethekile lomanyolo livame ukusetshenziswa ngaphansi kwezinga lokushisa eliphezulu kanye nokucindezela okukhulu, futhi ipayipi izokwenziwa i-oxidized futhi igqwale ngaphansi kwesenzo segesi ephezulu yokushisa yokushisa kanye nomhwamuko wamanzi.Ipayipi lensimbi liyadingeka ukuze libe namandla ahlala njalo, i-oxidation ephezulu kanye nokumelana nokugqwala, nokuzinza okuhle kwenhlangano.

(2) Inhloso:

①Amapayipi ensimbi omanyolo wamakhemikhali asetshenziswa kakhulu ukwenza amapayipi odonga lwamanzi, amapayipi amanzi abilayo, amapayipi esitimu ashisa kakhulu, amapayipi esitimu ashisa kakhulu amabhoyela esitimela, amapayipi entuthu amakhulu namancane kanye namapayipi ezitini ezikhothame.

②Ipayipi lensimbi elisetshenziselwa ngokukhethekile umanyolo lisetshenziselwa kakhulu ukwakha ipayipi le-superheater, ipayipi lokufudumeza, ipayipi lomoya, ipayipi lesitimu esikhulu, njll. ye-high-pressure kanye ne-ultra-high pressure boiler.
