Chitoliro chachitsulo cha aloyi P22(Giredi A335 P22, zinthu 2.25Cr-1Mo) ndi chitsulo cholimba chomwe chimagwiritsidwa ntchito kwambiri chomwe chimalimbana ndi kutentha kwa chromium-molybdenum. Chifukwa cha mphamvu yake yabwino kwambiri yotenthetsera, kukana kukwera kwabwino, komanso kukana kukhuthala kwa okosijeni, chimagwira ntchito yofunika kwambiri m'magawo angapo ofunikira a mafakitale pamsika waku India.

Madera Ofunika Kwambiri Ogwiritsira Ntchito Akuphatikizapo:

Kupanga Mphamvu (Ntchito Yaikulu):

Malo Opangira Mphamvu Zotentha: Ndi chinthu chofunikira kwambiri pa ma boiler m'magawo osafunikira kwenikweni komanso ena ofunikira kwambiri. Amagwiritsidwa ntchito kwambiri popanga machubu a superheater, machubu obwezeretsanso mphamvu, mapaipi akuluakulu a nthunzi, ndi ma headers otentha kwambiri. Pamene India ikupitiliza kukulitsa zomangamanga zake zamagetsi kuti ikwaniritse zosowa zachuma, kugwiritsa ntchitoChitoliro cha P22s mu gawoli ikukhazikikabe.

Kukonza ndi Kuyeretsa Mafuta:

Amagwiritsidwa ntchito popanga mapaipi otentha kwambiri opangira mayunitsi opangira ma hydroprocessing mu fakitale yoyeretsera, mayunitsi opangira ma catalytic, machubu osinthira kutentha, ndi mapaipi onyamula mafuta ndi gasi otentha kwambiri. Kukana kwake ku hydrogen ndi dzimbiri la sulfure kumapangitsa kuti ikhale yoyenera malo ovuta a petrochemical.

Makampani Opangira Feteleza:

Amagwiritsidwa ntchito m'mafakitale opanga ammonia, urea, ndi zina zotero, popangira mapaipi a gasi ndi zida zotenthetsera kwambiri, monga mapaipi a reformer ndi waste heat boiler.

Makampani Ena:

Imagwiritsidwanso ntchito m'maboiler a mafakitale, zosinthira kutentha, ndi zotengera zosiyanasiyana zopanikizika zomwe zimagwira ntchito kutentha kwambiri (nthawi zambiri pafupifupi 550°C-600°C).

Makhalidwe a Msika wa ku India:

Zoyambitsa Kufunikira: Kufunika kumeneku kumachitika makamaka chifukwa cha mapulojekiti amagetsi apakhomo (zomanga zatsopano ndi zokonzanso), kukulitsa mphamvu za mafakitale oyeretsera, komanso kukula kwa mafakitale oyambira.

Magwero Ogulira: Msika umaperekedwa ndi zinthu zonse ziwiri (makamaka zochokera ku China, Japan, Europe, ndi zina zotero) komanso opanga aku India (monga ISMT), zomwe zimapangitsa kuti pakhale mpikisano waukulu. Mtengo, khalidwe, nthawi yotumizira, ndi ntchito zakomweko ndi zinthu zofunika kwambiri pa mpikisano.

Miyezo ndi Ziphaso: Mapulojekiti nthawi zambiri amatsatira miyezo ya ASME/ASTM ndipo angafunikenso kutsatira miyezo ya ku India kapena zofunikira za polojekiti. Kupeza ziphaso zoyenera (monga zokhudzana ndi IBR - Indian Boiler Regulations) ndikofunikira kwambiri kuti msika ulowe.

Mavuto ndi Zochitika: Akukumana ndi mpikisano wochokera ku zipangizo zapamwamba (monga P91/P92) m'magawo apamwamba komanso kupsinjika kwa mtengo. Pali kugogomezera kwakukulu pamsika pa ubwino wa malonda, kudalirika, ndi kukhazikika kwa unyolo woperekera katundu.

Mwachidule, chitoliro chachitsulo cha alloy P22 ndi chinthu chofunikira kwambiri m'mafakitale monga magetsi ndi mankhwala a petrochemical ku India. Ngakhale kuti pali zovuta ndi zipangizo zatsopano zaukadaulo, kudalirika kwake, kugwiritsa ntchito bwino ndalama, komanso kuyenerera kukonza, kukonzanso, komanso mapulojekiti ambiri otentha apakatikati mpaka okwera kwambiri amatsimikizira kuti chidzakhalabe ndi gawo lokhazikika komanso lofunika pamsika mtsogolomu.
