Taw qhia: Seamless alloy steel kav yog cov khoom tseem ceeb hauv kev lag luam boiler, muab kev kub siab thiab siab-resistant kev daws teeb meem rau ntau yam kev siv. Cov kav dej no ua raws li cov qauv nruj raws li ASTM A335, nrog rau qib xws liP5, P9, thiab P11, ua kom muaj kev ua tau zoo dua, ua haujlwm ntev, thiab kev ntseeg siab hauv kev ua haujlwm boiler.

ASTM A335 TxujASTM A335 yog ib qho kev qhia tshwj xeeb uas npog seamless ferritic alloy-steel yeeb nkab rau kev pabcuam kub. Nws yog dav lees paub thiab tau txais kev pom zoo hauv kev lag luam boiler vim nws cov kev cai nruj rau cov khoom siv kho tshuab, tshuaj muaj pes tsawg leeg, thiab cov txheej txheem kuaj. Cov qauv no yog qhov tseem ceeb hauv kev ua kom zoo thiab kev nyab xeeb ntawm cov kav hlau alloy steel siv hauvhigh-pressure thiab high-temperature boilertshuab.

Cov Khoom Siv thiab Qib: Cov kav hlau hlau muaj nyob hauv ntau qib, suav nrog P5, P9, thiab P11, txhua tus tsim los ua kom tau raws li qhov xav tau ntawm qhov kub thiab txias. P5 muaj kev tiv thaiv zoo heev rau corrosion, ua rau nws haum rau nruab nrab mus rau high-temperature daim ntaub ntawv. P9 yog lub npe hu rau nws lub zog tshwj xeeb thiab tawv, ua rau nws zoo tagnrho rau kev xav tau ib puag ncig boiler. P11 khav theeb muaj zog tensile thiab kub tsis kam, ua rau nws tsim nyog rau cov ntawv thov kub dua.

Qhov zoo: Seamless alloy steel kav muaj ntau qhov zoo uas ua rau lawv nyiam xaiv hauv kev lag luam boiler. Ua ntej thiab qhov tseem ceeb, lawv cov kev tsim kho seamless tshem tawm txoj kev pheej hmoo ntawm kev xau, ua kom muaj kev nyab xeeb thiab ua haujlwm zoo boiler. Cov ntsiab lus alloying hauv cov kav dej no txhim kho lawv cov kev tiv thaiv oxidation thiab scaling, tswj lawv cov qauv kev ncaj ncees txawm nyob rau hauv huab cua. Cov kav dej muaj peev xwm tiv taus kev kub siab thiab kub hloov pauv yam tsis muaj deformation lossis tsis ua haujlwm ua rau lawv lub neej ua haujlwm ntev thiab kev saib xyuas tsis zoo.

Daim ntaub ntawv: Seamless alloy steel kav, lub rooj sib thamASTM A335 tus qauv, nrhiav kev siv dav hauv ntau yam kev siv boiler. Lawv feem ntau ua haujlwm hauv cov chaw tsim hluav taws xob, qhov chaw uas lawv ua haujlwm tseem ceeb rau cov superheaters, reheaters, thiab waterwalls. Kev lag luam roj thiab roj kuj tso siab rau cov kav dej no rau cov kav dej thiab cov chaw ua haujlwm kub. Tsis tas li ntawd, lawv yog siv nyob rau hauv refineries thiab petrochemical nroj tsuag rau daim ntaub ntawv uas xav kom siab kub thiab siab tsis kam.

Xaus: Hauv kev xaus, seamless alloy steel kav ua raws liASTM A335 tus qauvthiab featuring qib P5, P9, thiab P11 muab cov kev daws teeb meem tseem ceeb rau kev lag luam boiler. Nrog rau lawv cov khoom tshwj xeeb, cov kav dej no ua kom muaj kev nyab xeeb thiab txhim khu kev qha boiler ua haujlwm, ua rau lawv qhov kev xaiv zoo tshaj plaws rau kev siv kub thiab kub siab. Lawv cov kev siv dav hauv ntau qhov kev lag luam ua pov thawj rau lawv txoj kev ntseeg siab, ua haujlwm ntev, thiab muaj peev xwm tiv taus huab cua, ua rau lawv yog ib feem tseem ceeb ntawm cov tshuab boiler niaj hnub.
