Kev Taw Qhia Txog Cov Hlau Uas Muaj Cov Hlau Carbon Zoo Thiab Cov Hlau Uas Muaj Cov Hlau Uas Tsis Muaj Qhov Txuas Rau Cov Kav Dej Boiler Uas Muaj Siab Thiab Siab Dua

GB/T5310Cov kav hlau tsis muaj qhov txuas yog cov khoom zoo tsim los rau cov kav dej boiler siab thiab siab dua. Lawv yog ua los ntawm cov hlau carbon zoo thiab cov hlau alloy kom ntseeg tau tias lawv ua tau zoo heev thiab ntseeg tau hauv qhov kub thiab txias thiab siab. Cov kav hlau tsis muaj qhov txuas no yog siv dav hauv kev tsim cov kav dej boiler thiab cov khoom hloov pauv cua sov, muab kev lees paub zoo rau kev tsim khoom lag luam.

Cov qib tseem ceeb

GB/T5310Cov kav hlau tsis muaj qhov txuas yog ua los ntawm Cr-Mo alloy thiab Mn alloy, thiab cov qib tseem ceeb suav nrog20G, 20Mg, 20MoG, 12CrMoG, thiab lwm yam. Cov ntaub ntawv no muaj lub zog kub zoo heev thiab tiv taus oxidation, thiab siv tau ntev hauv qhov chaw ua haujlwm hnyav yam tsis muaj kev puas tsuaj. Ntawm lawv:

20G: Cov hlau ua los ntawm cov pa roj carbon zoo nrog kev ua tau zoo thiab kev tawv, feem ntau siv rau hauv cov kav dej boiler nruab nrab thiab qis siab.
20Mg: Ntxiv manganese rau 20G ntxiv txhim kho lub zog thiab qhov nyuaj ntawm cov khoom siv, tsim nyog rau cov kav dej boiler nruab nrab thiab siab.
20MoG: Molybdenum ntxiv rau 20G, uas ua rau lub zog cua sov thiab lub zog nkag mus zoo dua, thiab tsim nyog rau cov kav dej boiler siab.
12CrMoG: Cov hlau sib xyaw ua ke uas muaj chromium thiab molybdenum, nrog kev tiv thaiv oxidation kub zoo heev thiab lub zog kub siab, tsim nyog rau cov kav dej boiler ultra-high-pressure.
Cov qib hlau sib xyaw ua ke

Cov qib hlau sib xyaw ua ke ntawm GB/T5310 tus qauv seamless steel kav kuj suav nrog 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, thiab lwm yam. Cov qib ntawm cov kav hlau no muaj cov khoom siv sib txawv thiab cov qib siv tau raws li cov tshuaj sib txawv thiab cov txheej txheem kho cua sov:

15MoG thiab 20MoG: Qhov ntxiv ntawm cov molybdenum tsim nyog ua rau lub zog kub thiab kev tiv thaiv corrosion ntawm cov yeeb nkab hlau zoo dua.
12CrMoG thiab15CrMoG: Qhov ntxiv ntawm chromium thiab molybdenum ua rau kom muaj kev tiv thaiv oxidation thiab lub zog kub ntawm cov yeeb nkab hlau, thiab nws tsim nyog rau cov chaw uas muaj qhov kub thiab txias dua.
12Cr2MoG thiab 12CrMoVG: Cov khoom sib xyaw ua ke tau zoo dua, nrog rau lub zog kub thiab kev tiv taus oxidation, thiab ua tau zoo tshwj xeeb hauv qhov chaw kub heev.
Cov ntawv thov
Cov kav hlau tsis muaj qhov txuas GB/T5310 siv dav hauv cov kav dej boiler thiab cov khoom siv hloov cua sov, feem ntau yog siv rau hauv cov khoom siv kub thiab siab xws li cov chaw tsim hluav taws xob boiler, cov boiler kev lag luam, thiab cov boiler cua sov pov tseg. Cov kav hlau tsis muaj qhov txuas no tuaj yeem tiv taus qhov siab ua haujlwm thiab kub heev, ua kom cov boiler thiab cov khoom siv hloov cua sov ua haujlwm tau zoo thiab siv tau ntev. Tsis tas li ntawd, cov kav hlau no kuj siv rau hauv cov khoom siv hloov cua sov hauv kev lag luam petrochemical, thiab nthuav dav lawv cov chaw siv.
Kev Txheeb Xyuas
GB/T5310 tus qauv seamless steel yeeb nkab tau dhau los ua cov khoom nyiam rau cov yeeb nkab siab thiab siab dua boiler vim lawv cov khoom siv zoo heev thiab ntau yam kev siv. Txawm hais tias nws yog 20G, 20Mg, 20MoG, 12CrMoG thiab lwm yam khoom siv, lossis 15MoG, 20MoG, 12CrMoG thiab lwm yam hlau alloy, lawv txhua tus ua pov thawj zoo heev rau kev tiv thaiv oxidation kub thiab lub zog kub, muab kev lees paub txhim khu kev qha rau kev ua haujlwm zoo thiab kev nyab xeeb ntawm cov khoom siv kev lag luam.
