Cov yeeb nkab hlau sib xyaw P22(Qib A335 P22, khoom siv 2.25Cr-1Mo) yog cov hlau chromium-molybdenum uas tiv taus cua sov uas siv dav. Vim nws lub zog kub zoo heev, tiv taus kev nkag mus zoo, thiab tiv taus oxidation, nws ua lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam tseem ceeb hauv kev lag luam Is Nrias teb.

Cov Cheeb Tsam Tseem Ceeb ntawm Daim Ntawv Thov suav nrog:

Kev Tsim Hluav Taws Xob (Kev Siv Tseem Ceeb):

Cov Chaw Fais Fab Thermal: Nws yog ib qho khoom siv tseem ceeb rau cov boilers hauv subcritical thiab qee qhov supercritical units. Nws yog siv dav rau kev tsim cov raj superheater, cov raj reheater, cov kav dej loj, thiab cov taub hau kub siab. Raws li Is Nrias teb txuas ntxiv nthuav nws cov khoom siv fais fab kom tau raws li kev thov kev loj hlob ntawm kev lag luam, daim ntawv thov ntawmP22 yeeb nkabs nyob rau hauv qhov kev lag luam no tseem ruaj khov.

Petrochemical & Refining:

Siv rau hauv kev tsim cov kav dej kub rau cov chaw ua roj refinery hydroprocessing, cov chaw tawg catalytic, cov raj xa cua sov, thiab cov kav dej xa cov roj thiab cov roj kub. Nws tiv taus kev tawm tsam hydrogen kub thiab sulfur corrosion ua rau nws haum rau cov chaw ua roj av hnyav.

Kev Lag Luam Chiv:

Siv rau hauv cov nroj tsuag tsim ammonia, urea, thiab lwm yam, rau cov kav dej roj thiab cov khoom siv hauv qab qhov kub thiab txias siab, xws li cov kav dej reformer thiab cov kav dej boiler pov tseg.

Lwm Cov Lag Luam:

Kuj pom daim ntawv thov hauv cov boilers kev lag luam, cov khoom hloov cua sov, thiab ntau yam khoom siv siab uas ua haujlwm ntawm qhov kub siab (feem ntau nyob ib puag ncig 550 ° C-600 ° C).

Cov yam ntxwv ntawm kev ua lag luam hauv Is Nrias teb:

Cov Kev Tsav Tsheb Xav Tau: Qhov kev xav tau feem ntau yog tsav los ntawm cov phiaj xwm fais fab hauv tsev (kev tsim kho tshiab thiab kev kho dua tshiab), kev nthuav dav peev xwm ntawm lub chaw ua roj, thiab kev loj hlob hauv cov lag luam tseem ceeb.

Cov Chaw Muab Khoom: Kev ua lag luam yog muab los ntawm ob qho tib si xa khoom tuaj (feem ntau yog los ntawm Tuam Tshoj, Nyiv Pooj, Tebchaws Europe, thiab lwm yam) thiab cov chaw tsim khoom hauv Is Nrias teb (piv txwv li, ISMT), ua rau muaj kev sib tw hnyav. Tus nqi, qhov zoo, lub sijhawm xa khoom, thiab kev pabcuam hauv zos yog cov yam tseem ceeb ntawm kev sib tw.

Cov Qauv & Daim Ntawv Pov Thawj: Cov phiaj xwm feem ntau ua raws li cov qauv ASME/ASTM thiab kuj tseem yuav xav tau kev ua raws li cov qauv Is Nrias teb lossis cov lus qhia tshwj xeeb rau cov phiaj xwm. Kev tau txais cov ntawv pov thawj cuam tshuam (piv txwv li, cuam tshuam nrog IBR - Indian Boiler Regulations) yog qhov tseem ceeb rau kev nkag mus rau hauv kev lag luam.

Cov Kev Cov nyom & Cov qauv: Ntsib kev sib tw los ntawm cov ntaub ntawv qib siab dua (piv txwv li, P91 / P92) hauv cov chav ntsuas siab dua thiab kev nyuaj siab ntawm tus nqi. Muaj kev lag luam loj hlob ntawm kev tsom mus rau qhov zoo ntawm cov khoom, kev ntseeg siab, thiab kev ruaj khov ntawm cov khoom xa tuaj.

Hauv kev xaus, cov yeeb nkab hlau alloy P22 yog cov khoom siv tseem ceeb rau cov lag luam tseem ceeb xws li lub zog thiab petrochemicals hauv Is Nrias teb. Txawm hais tias muaj kev sib tw los ntawm cov ntaub ntawv tshiab, nws qhov kev ntseeg tau, kev siv nyiaj tsim nyog, thiab kev tsim nyog rau kev saib xyuas, kev kho dua tshiab, thiab ntau qhov project kub nruab nrab mus rau siab ua kom nws yuav tswj tau qhov ruaj khov thiab tseem ceeb ntawm kev lag luam yav tom ntej.
