Kev Taw Qhia: Cov kav hlau tsis muaj hlau sib xyaw yog cov khoom tseem ceeb hauv kev lag luam boiler, muab cov kev daws teeb meem kub thiab siab rau ntau yam kev siv. Cov kav dej no ua raws li cov qauv nruj uas tau teeb tsa los ntawm ASTM A335, nrog rau cov qib xws liP5, P9, thiab P11, ua kom muaj kev ua tau zoo tshaj plaws, kev ruaj khov, thiab kev ntseeg tau hauv kev ua haujlwm boiler.

ASTM A335 Cov QauvASTM A335 yog ib qho kev qhia tshwj xeeb uas npog cov yeeb nkab ferritic alloy-steel seamless rau kev pabcuam kub siab. Nws tau lees paub dav thiab siv rau hauv kev lag luam boiler vim nws cov kev cai nruj rau cov khoom siv kho tshuab, cov tshuaj lom neeg sib xyaw, thiab cov txheej txheem kuaj. Cov qauv no yog qhov tseem ceeb hauv kev ua kom zoo thiab kev nyab xeeb ntawm cov yeeb nkab hlau alloy siv hauvboiler siab thiab kubcov txheej txheem.

Cov Khoom Siv thiab Qib: Cov kav hlau alloy muaj nyob rau hauv ntau qib, suav nrog P5, P9, thiab P11, txhua tus tsim los ua kom tau raws li qhov kub thiab txias tshwj xeeb. P5 muaj kev tiv thaiv zoo heev rau kev xeb, ua rau nws haum rau kev siv nruab nrab mus rau qhov kub siab. P9 paub txog nws lub zog tshwj xeeb thiab kev tawv, ua rau nws zoo tagnrho rau cov chaw boiler xav tau. P11 muaj lub zog tensile ntau dua thiab kev tiv thaiv kub, ua rau nws haum rau kev siv kub siab dua.

Cov Zoo: Cov kav hlau tsis muaj hlau sib xyaw muaj ntau yam zoo uas ua rau lawv yog qhov kev xaiv zoo tshaj plaws hauv kev lag luam boiler. Ua ntej tshaj plaws, lawv txoj kev tsim kho tsis muaj hlau sib xyaw ua rau muaj kev pheej hmoo ntawm kev xau, ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo ntawm boiler. Cov khoom sib xyaw hauv cov kav dej no ua rau lawv tiv taus kev oxidation thiab kev tawg, tswj lawv cov qauv kom ruaj khov txawm tias nyob rau hauv qhov xwm txheej hnyav. Lub peev xwm ntawm cov kav dej kom tiv taus qhov siab thiab qhov kub hloov pauv yam tsis muaj kev hloov pauv lossis kev ua tsis tiav ua rau lawv lub neej ntev thiab tsis tas yuav saib xyuas ntau.

Daim Ntawv Thov: Seamless alloy steel kav dej, kev sib ntsibASTM A335 cov qauv, nrhiav kev siv dav hauv ntau yam kev siv boiler. Lawv feem ntau siv rau hauv cov chaw tsim hluav taws xob, qhov chaw uas lawv ua haujlwm ua cov khoom tseem ceeb rau cov superheaters, reheaters, thiab waterwalls. Kev lag luam roj thiab roj kuj vam khom cov kav dej no rau cov kav dej thiab cov chaw ua haujlwm kub siab. Tsis tas li ntawd, lawv siv rau hauv cov chaw ua roj thiab cov chaw tsim roj av rau cov ntawv thov uas xav tau qhov kub thiab txias siab.

Xaus Lus: Hauv kev xaus lus, cov kav hlau tsis sib xyaw ua ke raws liASTM A335 cov qauvthiab muaj cov qib P5, P9, thiab P11 muab cov kev daws teeb meem tseem ceeb rau kev lag luam boiler. Nrog lawv cov yam ntxwv tshwj xeeb, cov kav dej no ua kom muaj kev nyab xeeb thiab txhim khu kev qha kev ua haujlwm boiler, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau kev siv kub thiab siab. Lawv siv dav hauv ntau yam kev lag luam ua pov thawj rau lawv qhov kev ntseeg tau, kev ruaj khov, thiab muaj peev xwm tiv taus cov xwm txheej hnyav, ua rau lawv yog ib feem tseem ceeb ntawm cov txheej txheem boiler niaj hnub.
