- Imizekelo yokuvavanya i-bend iya kugotywa kwiqondo lokushisa lokushisa nge-180 ngaphandle kokuqhekeka ngaphandle kwesahlulo esigobileyo.
AI-STM A335 P5iityhubhu zentsimbi ezingenamthungo zilungele amanzi, umphunga, ihydrogen, ioli emuncu, njl.njl. Ukuba isetyenziselwa umphunga wamanzi, ubushushu bayo obuphezulu bokusebenza bungama-650.℃; Xa isetyenziswa kwindawo yokusebenza efana neoyile emuncu, inobushushu obuphezulu bobushushu bokumelana nokukhula kwesulfure, kwaye ihlala isetyenziswa kwiimeko zobushushu obuphezulu be-sulphur corrosion ye-288 ~ 550℃.
Inkqubo yokuvelisa:
1. Ukuqengqeleka okushushu (ityhubhu yentsimbi ekhutshiweyo engenamthungo) : ityhubhu engqukuva yebillet → ukufudumeza → ukugqobhoza → ukuqengqeleka okunqamlezayo okuqengqelekayo okuqengqelekayo → ukuhluba ityhubhu → ukulinganisa (okanye ukunciphisa) → ukupholisa → ukolula → uvavanyo loxinzelelo lwamanzi (okanye ukufumanisa isiphene ) → ukuphawula → ugcino
2. Umzobo obandayo (uqengqeleka) ityhubhu yentsimbi engenamthungo: ityhubhu engqukuva → ukufudumeza → ukugqobhoza → isihloko → ukuqhola → ukuchola → ukufakwa kwe-oyile (icwecwe lobhedu) → umzobo obandayo ohamba ngeendlela ezininzi (ukuqengqeleka okubandayo) → ityhubhu engenanto → unyango lobushushu → ukulungisa → amanzi uvavanyo loxinzelelo (uphawu lwesiphene) → ukuphawula → ugcino

I-A335 P22 yintsimbi ye-2.25Cr-1Mo Chromium-molybdenum Ubushushu obuphezulu bentsimbi yeebhoyila kunye nezifudumezi ezinkulu,I-ASTM A335/A335Mumgangatho. Kwi-1985, yatshintshwa kwi-GB5310 kwaye yabizwa ngokuba yi-12Cr2MoG. Amanye amazwe anamabakala entsimbi afanayo, afana neFederal Republic of Germany 10CrMo910 kunye neJapan STBA24. Kuluhlu lwentsimbi ye-cr-1Mo, amandla ayo ashushu aphezulu kakhulu, phantsi kobushushu obufanayo (iqondo lobushushu≤580℃) amandla ayo okuqhekeka kwesikrufu kunye noxinzelelo oluvumelekileyo lungaphezulu nangaphezulu kunentsimbi ye-9CR-1Mo, kwaye inokusebenza kakuhle kokusetyenzwa kunye nokusebenza kwe-welding, iplastikhi elungileyo ehlala ixesha elide. Ke ngoko, isetyenziswe ngokubanzi kwindawo yokusebenza erhabaxa, njengamandla obushushu, amandla enyukliya kunye nezinye izixhobo ze-hydrogen kwimibhobho eyahlukeneyo yokufudumeza kunye neenqanawa zoxinzelelo oluphezulu.
Ubushushu obuvumelekileyo: A335P22 (SA-213T22) isetyenziswa ikakhulu kwi-300,600MW kunye nezinye isityalo samandla esikhulu sebhoyila eludongeni lobushushu.≤580℃iheater enkulu kunye nodonga lobushushu ityhubhu & LT;540℃umbhobho womphunga eludongeni kunye nentloko, olu hlobo lwentsimbi luye lwasetyenziswa ngokubanzi eUnited States, eJapan naseYurophu, lunembali ende yokusebenza kwizityalo zamandla, lusebenza oluzinzileyo, ukusebenza kakuhle kwenkqubo yentsimbi evuthiweyo.
Intsimbi ye-12Cr1MoV yeye-chromium-molybdenum vanadium yentsimbi ye-vanadium, isetyenziselwa ikakhulu i-12Cr1MoV/GB5310 yentsimbi yombhobho. Isetyenziswa kakhulu, bubushushu obukwi-480℃~580℃indawo yokushisa ephezulu kunye nenye yezona zinto zininzi. I-12Cr1MoVG yobushushu benkonzo yetyhubhu yentsimbi: isetyenziselwa eyona ntsimbi ingundoqo yetyhubhu ye-superheater, iheader kunye nombhobho womphunga webhoyila yoxinzelelo oluphezulu obushushu bodonga lwetyhubhu bungaphantsi okanye bulingana no-580.℃.
Inkqubo yokuvelisa:Uvavanyo lobulukhuni:
1. Ukuqengqeleka okushushu (ityhubhu yentsimbi ekhutshiweyo engenamthungo) : ityhubhu engqukuva yebillet → ukufudumeza → ukugqobhoza → ukuqengqeleka okunqamlezayo okuqengqelekayo okuqengqelekayo → ukuhluba ityhubhu → ukulinganisa (okanye ukunciphisa) → ukupholisa → ukolula → uvavanyo loxinzelelo lwamanzi (okanye ukufumanisa isiphene ) → ukuphawula → ugcino
2. Umzobo obandayo (uqengqeleka) ityhubhu yentsimbi engenamthungo: ityhubhu engqukuva → ukufudumeza → ukugqobhoza → isihloko → ukuqhola → ukuchola → ukufakwa kwe-oyile (icwecwe lobhedu) → umzobo obandayo ohamba ngeendlela ezininzi (ukuqengqeleka okubandayo) → ityhubhu engenanto → unyango lobushushu → ukulungisa → amanzi uvavanyo loxinzelelo (uphawu lwesiphene) → ukuphawula → ugcino
Ukupakisha:
Ukupakishwa okungenanto / ukupakishwa kwebhandle / ukupakishwa kwekhreyithi / ukhuseleko lwamaplanga kumacala omabini eityhubhu kwaye ikhuselwe ngokufanelekileyo ukuhanjiswa okuxabisa ulwandle okanye njengoko kuceliwe.
