Umbhobho wentsimbi ye-alloy P22(Ibanga A335 P22, izinto eziyi-2.25Cr-1Mo) yintsimbi ye-alloy exhathisa ubushushu esetyenziswa kakhulu yi-chromium-molybdenum. Ngenxa yamandla ayo aphezulu obushushu, ukumelana okuhle nokuqhekeka, kunye nokumelana ne-oxidation, idlala indima ebalulekileyo kumacandelo aliqela aphambili emizi-mveliso kwimarike yaseIndiya.

Iindawo eziphambili zokusetyenziswa ziquka:

Ukuveliswa koMbane (Isicelo esiPhambili):

Izityalo zamandla obushushu: Zizinto ezibalulekileyo kwiibhoyila ezikwiiyunithi ezingaphantsi kobunzima obufunekayo nakwezinye ezingaphantsi kobunzima obufunekayo. Zisetyenziswa kakhulu ekwenzeni iityhubhu ze-superheater, iityhubhu ze-reheater, iipayipi eziphambili zomphunga, kunye neentloko zobushushu obuphezulu. Njengoko i-India iqhubeka nokwandisa iziseko zayo zamandla ukuhlangabezana neemfuno zokukhula koqoqosho, ukusetyenziswa kweUmbhobho we-P22kweli candelo lihlala lizinzile.

I-Petrochemical kunye nokuCoca:

Isetyenziswa ekwenzeni imibhobho yenkqubo yobushushu obuphezulu kwiiyunithi zokucoca amanzi, iiyunithi zokuqhekeka kwe-catalytic, iityhubhu zokutshintsha ubushushu, kunye nemibhobho ehambisa imijelo yeoyile negesi yobushushu obuphezulu. Ukuxhathisa kwayo ukuhlaselwa yi-hydrogen yobushushu obuphezulu kunye nokugqwala kwesulfure kuyenza ifaneleke kwiindawo ezinobungozi ze-petrochemical.

Ishishini lezichumisi:

Isetyenziswa kwizityalo ezivelisa i-ammonia, i-urea, njl.njl., kwiipayipi zegesi zenkqubo kunye nezixhobo eziphantsi kobushushu obuphezulu kunye noxinzelelo, ezifana neepayipi zebhoyila yokufudumala kunye ne-waste heat.

Amanye Amashishini:

Ikwasetyenziswa nakwiibhoyila zoshishino, kwii-heat exchangers, nakwii-vessels ezahlukeneyo ezisebenza kumaqondo obushushu aphezulu (ngesiqhelo malunga ne-550°C-600°C).

Iimpawu zeMarike yaseIndiya:

Izinto Ezibangela Imfuno: Imfuno iqhutywa ikakhulu ziiprojekthi zamandla zasekhaya (ukwakhiwa okutsha kunye nokulungiswa), ukwandiswa kwamandla okucoca, kunye nokukhula kumashishini asisiseko.

Imithombo yoNikezelo: Imakethi ibonelelwa zizinto ezivela kwamanye amazwe (ikakhulu ezivela eTshayina, eJapan, eYurophu, njl.njl.) kunye nabavelisi basekhaya baseIndiya (umz., i-ISMT), nto leyo ebangela ukhuphiswano olukhulu. Ixabiso, umgangatho, ixesha lokuhanjiswa, kunye nenkonzo yasekuhlaleni zizinto eziphambili zokhuphiswano.

Imigangatho kunye neSatifikethi: Iiprojekthi zihlala zilandela imigangatho ye-ASME/ASTM kwaye zinokufuna ukuthotyelwa kwemigangatho yaseIndiya okanye iinkcukacha ezithile zeprojekthi. Ukufumana iziqinisekiso ezifanelekileyo (umz., ezinxulumene ne-IBR - Indian Boiler Regulations) kubalulekile ekungeneni kwimarike.

Imingeni kunye neendlela ezisetyenziswayo: Ijongene nokhuphiswano oluvela kwizixhobo ezikumgangatho ophezulu (umz., i-P91/P92) kwiiyunithi zeparameter eziphezulu kunye noxinzelelo lweendleko. Kukho ukugxininiswa okukhulayo kwimarike kumgangatho wemveliso, ukuthembeka, kunye nozinzo lwekhonkco lobonelelo.

Ngamafutshane, ipayipi yentsimbi ye-alloy P22 sisixhobo esibalulekileyo kumashishini angundoqo afana namandla kunye neekhemikhali zepetrochemicals eIndiya. Nangona ijongene neengxaki ngezixhobo zobugcisa ezintsha, ukuthembeka kwayo okuqinisekisiweyo, ukusebenza kakuhle kweendleko, kunye nokufaneleka kokugcinwa, ukulungiswa kwakhona, kunye neeprojekthi ezininzi zeparameter zobushushu obuphakathi ukuya phezulu ziqinisekisa ukuba iya kugcina isabelo semarike esizinzileyo nesibalulekileyo kwixesha elizayo.
