Cov yeeb nkab hlau tsis muaj qhov sib txuas yog ua los ntawm cov txheej txheem ua haujlwm kub xws li kev dov kub perforated. Yog tias tsim nyog, cov yeeb nkab kub ua haujlwm tuaj yeem ua haujlwm txias ntxiv kom tau raws li cov duab, qhov loj me thiab kev ua tau zoo. Tam sim no, cov yeeb nkab hlau tsis muaj qhov sib txuas yog cov yeeb nkab siv ntau tshaj plaws hauv cov chaw tsim khoom petrochemical.

Kev Tshuaj Xyuas: kev tshuaj xyuas cov tshuaj lom neeg, kev sim nruj, kev sim ua kom tiaj tus thiab kev sim siab dej yuav tsum tau ua rau ntawm cov yeeb nkab hlau siv rau kev thauj mus los ntawm cov kua dej dav dav.

GB5310, GB6479, GB9948Peb hom yeeb nkab hlau txheem, ntxiv rau lub raj xa dej yuav tsum tau kuaj xyuas, tab sis kuj yuav tsum tau ua qhov kev sim flaring thiab kev sim cuam tshuam; Cov kev cai tshuaj xyuas kev tsim khoom ntawm peb hom yeeb nkab hlau no nruj heev.

GB6479tus qauv kuj tseem ua rau muaj kev cai tshwj xeeb rau qhov kub qis cuam tshuam rau cov khoom siv.

GB3087 tus qauv yeeb nkab hlau, ntxiv rau qhov kev cai dav dav rau kev thauj cov kua dej yeeb nkab hlau, tab sis kuj xav tau kev sim khoov txias.

GB/T8163 tus qauv yeeb nkab hlau, ntxiv rau qhov kev cai dav dav rau cov yeeb nkab hlau thauj dej, raws li qhov yuav tsum tau ua ntawm daim ntawv cog lus los ua qhov kev sim flaring thiab kev sim khoov txias. Cov kev cai tsim khoom ntawm ob hom yeeb nkab no tsis nruj npaum li cov ntawm thawj peb hom.

Kev Tsim Khoom: GB / T / 8163 thiab GB3087 tus qauv yeeb nkab hlau txais yuav qhib lub cub tawg lossis hloov pauv smelting, nws cov khoom tsis huv thiab cov qhov tsis zoo sab hauv yog ntau dua.

GB9948kev siv hluav taws xob los ua kom sov. Feem ntau yog ntxiv rau hauv cov txheej txheem ua kom sov nrog ob peb yam khoom xyaw thiab cov qhov tsis zoo sab hauv.

GB6479thiabGB5310cov qauv lawv tus kheej qhia meej txog cov kev cai rau kev ua kom huv sab nraum lub cub tawg, nrog rau qhov tsis huv thiab qhov tsis zoo sab hauv tsawg kawg nkaus thiab cov khoom siv zoo tshaj plaws.

Cov qauv yeeb nkab hlau saum toj no yog tsim los ntawm qhov zoo los ntawm qis mus rau siab:

GB/T8163＜GB3087＜GB9948＜GB5310＜GB6479

Kev Xaiv: nyob rau hauv qhov xwm txheej ib txwm muaj, GB / T8163 tus qauv yeeb nkab hlau yog qhov tsim nyog rau qhov kub tsim tsawg dua 350 ℃, siab tsawg dua 10.0mpa cov khoom siv roj, roj thiab roj av thiab cov xwm txheej pej xeem;

Rau cov khoom siv roj, roj thiab roj av, thaum qhov kub tsim ntau dua 350 ℃ lossis siab ntau dua 10.0mpa, nws yog qhov tsim nyog los xaivGB9948 or GB6479cov yeeb nkab hlau txheem;

GB9948 or GB6479tus qauv kuj tseem yuav tsum tau siv rau cov kav dej ua haujlwm ze ntawm hydrogen lossis hauv qhov chaw muaj kev ntxhov siab.

Yuav tsum siv cov yeeb nkab carbon steel uas kub tsawg (tsawg dua -20 ℃)GB6479tus qauv, tsuas yog nws qhia txog qhov yuav tsum tau ua ntawm qhov kub qis cuam tshuam rau cov ntaub ntawv.

GB3087 thiabGB5310Cov qauv tau teeb tsa tshwj xeeb rau cov qauv yeeb nkab boiler. "Cov cai tswjfwm kev nyab xeeb ntawm Boiler" tau hais tias txhua yam txuas nrog cov raj boiler yog cov uas muaj feem cuam tshuam rau kev saib xyuas, kev siv cov khoom siv thiab tus qauv yuav tsum ua raws li cov cai ntawm kev nyab xeeb ntawm boiler, yog li ntawd, boiler, chaw nres tsheb fais fab, cua sov thiab cov khoom siv tsim khoom siv petrochemical siv rau hauv cov yeeb nkab pa pej xeem yuav tsum tau siv (los ntawm cov khoom siv system) GB3087 lossis tus qauvGB5310.

Nws yog ib qho tsim nyog sau tseg tias qhov zoo ntawm cov yeeb nkab hlau zoo, cov nqi yeeb nkab hlau kuj siab dua, xws liGB9948dua li tus nqi khoom siv GB8163 yuav luag 1/5, yog li ntawd, thaum xaiv cov qauv khoom siv yeeb nkab hlau, yuav tsum tau xav txog raws li cov xwm txheej ntawm kev siv, ob qho tib si txhim khu kev qha thiab kev lag luam. Nws kuj tseem yuav tsum tau sau tseg tias cov yeeb nkab hlau raws li GB / T20801 thiab TSGD0001, GB3087 thiab GB8163 yuav tsum tsis txhob siv rau hauv GC1 piping (tshwj tsis yog tias tus kheej ultrasonic, zoo tsis tsawg dua L2.5, tuaj yeem siv rau hauv GC1 (1) piping tsim siab tsis ntau dua 4.0Mpa).
