1. ASTM A213 304H Seamless Pipe Txheej txheem cej luam:

ASTM A213 Alloy 304H UNS S30409 Stainless hlau yeeb nkabyog cov kav dej kub tsis muaj steel hlau ua los ntawm Alloy 304H, uas yog austenitic chromium-nickel steel nrog cov ntsiab lus carbon ntau dua piv rau 304 thiab 304L. Cov pa roj carbon ntau ntxiv txhim kho nws qhov kub thiab txias zog thiab tiv thaiv oxidation. Nws yog qhov zoo tagnrho rau siv hauv high-pressure thiab high-temperature daim ntaub ntawv.

 

2. 304H Seamless Yeeb Nkab Qhov Zoo:

- High-Temperature Resistance: Cov ntsiab lus carbon ntau dua tso cai rau 304H kom muaj zog txhua yam zoo ntawm qhov kub siab (txog 800 degree). Qhov no ua rau nws tsim nyog rau cov ntawv siv hluav taws xob tiv taus piv rau 304 thiab 304L.

- Corrosion Resistance: Zoo li lwm qib ntawm 304,Alloy 304H UNS S30409 Stainless hlau yeeb nkabmuab kev tiv thaiv zoo tshaj plaws rau oxidation thiab corrosion, ua rau nws zoo tagnrho rau ib puag ncig raug acidic thiab corrosive hais.

- Zoo Weldability: Txawm hais tias muaj cov ntsiab lus carbon siab, 304H tuaj yeem welded siv cov txheej txheem vuam feem ntau. Kev kho cua sov ua ntej thiab tom qab vuam feem ntau yog tsim nyog los tiv thaiv cov ciam teb nag lossis daus.

- Durability thiab Longevity: Nrog nws lub peev xwm los tiv thaiv ob qho tib si kub thiab corrosive tej yam kev mob,ASTM A213 Alloy 304H yeeb nkabmuab ncua kev pab cuam lub neej nyob rau hauv kev xav tau ib puag ncig.

- Cov qauv kev ruaj ntseg: Vim nws cov qauv austenitic ruaj khov, 304H tsis cuam tshuam rau brittleness thiab khaws nws cov khoom siv hauv qab thermal stress.

3. ASTM A213 304H Stainless Hlau Yeeb Nkab Daim Ntawv Thov:

- Kev Tsim Hluav Taws Xob: 304H seamless kav feem ntau siv hauv boilers, tshav kub exchangers, thiab superheaters nyob rau hauv fais fab nroj tsuag vim lawv kub-resistant.

- Petrochemical Kev Lag Luam:Alloy 304H Seamless Yeeb Nkabyog qhov zoo tagnrho rau cov ntawv thov uas yuav tsum tau muaj kev kub siab thiab kub kub, xws li refining units thiab petrochemical nroj tsuag.

- Cov Khoom Siv Tshuaj Siv Tshuaj: Cov tshuaj tiv thaiv zoo heev ua rau nws tsim nyog rau cov kav dej hauv cov nroj tsuag tshuaj tuav cov tshuaj nruj heev.

- Kub Exchangers:UNS S30409 Seamless Yeeb Nkabyog siv nyob rau hauv lub tshav kub exchangers qhov kub hloov pauv ntau zaus, kom ntseeg tau tias cov yeeb nkab khoom tsis degrade nyob rau hauv thermal stress.

- Kev Lag Luam Roj & Roj: Ua haujlwm hauv cov kav dej rau cov roj thiab roj rho tawm, tshwj xeeb tshaj yog nyob rau hauv qhov chaw kub kub.

- Cov Khoom Siv Hluav Taws Xob: Haum rau cov khoom siv hluav taws xob thiab cov khoom siv kho cua sov vim nws cov thermal stability.

 

4. 304H Stainless Hlau Yeeb Nkab Txheej Txheem:

Kev tsim khoom ntawm ASTM A213 304H seamless kav suav nrog cov kauj ruam hauv qab no:

- Extrusion: Ib puag ncig steel billet yog rhuab thiab thawb los ntawm kev tuag los tsim cov yeeb nkab ntxhib.

- Ua haujlwm txias: LubAlloy 304H UNS S30409 Yeeb Nkabundergoes txias ua hauj lwm, nrog rau kev kos duab los yog dov, kom ua tau raws li qhov xav tau qhov ntev thiab txhim kho nto tiav thiab lub zog.

- Kev kho cua sov: Cov kav dej yog kho cua sov los txhim kho cov khoom siv kho tshuab thiab xyuas kom cov khoom khaws nws qhov kub thiab txias.ASTM A213 304H yeeb nkabtej zaum yuav yog cov tshuaj annealed los txo cov kev ntxhov siab sab hauv thiab optimize corrosion kuj.

- Kev Ntsuas & Kev Tshuaj Xyuas: Kev sim nruj yog ua tiav, suav nrog kev sim tensile, kev sim hardness, thiab tsis muaj kev puas tsuaj (xws li kev sim hydrostatic thiab kuaj ultrasonic) kom ntseeg tau tias cov yeeb nkab ua tau raws li cov qauv tsim nyog ASTM.

Los ntawm kev xaivA 213 304H S30409 Stainless Hlau Yeeb Nkabrau qhov kub thiab txias thiab corrosive ib puag ncig, koj tuaj yeem tau txais txiaj ntsig los ntawm kev ua tau zoo, ua haujlwm ntev, thiab kev siv nyiaj txiag.
