SMO 254 ERW YEEB yog siv qhov chaw uas cov khoom thiab corrosion tsis kam ntawm cov hlau yuav tsum muaj. Lub siab Molybdenum thiab chromium cov ntsiab lus tseem ua rau smoo 254 square raj muaj cov kua qaub uas tuaj yeem tiv thaiv pitting.
SAE 304 stainless hlau yog qhov feem ntau steel hlau. Cov hlau muaj ob txoj kev chromium (nruab nrab ntawm 18% thiab 20%) thiab thib pua (nruab nrab ntawm 8%) [1] cov hlau uas yog cov qauv hlau tseem ceeb. Nws yog ib tus neeg siv tshuaj hlau tsis huv. Nws tsis tshua muaj hluav taws xob thiab cuam tshuam cov khoom siv hluav taws xob ntau dua li cov hlau. Nws sib nqus, tab sis tsis sib nqus dua li hlau. Nws muaj ntau dua corrosion tsis kam ntau dua li cov hlau tsis tu ncua thiab siv dav siv vim yog qhov yooj yim nyob rau hauv ntau yam duab. [1]
SMO 254 Cov kav dej tuaj yeem tiv taus cov kev ntxhov siab ntawm cov neeg muaj kev ntxhov siab thiab alloy 254 smo yeeb nkab siab ua haujlwm nyob rau hauv cov kub thiab xeb ib puag ncig.
ASTM A182 F304 stainless hlau flanges yog tsim tau raws li Asme B16.5 150 #, 600 #, 900 #, 2500 #.
Qeb 310 \ / 310s Stainless hlau yog 25% chromium thiab 20% npib tsib xee, ua rau nws tiv taus oxidation thiab corrosion. Qib 310s yog cov pa roj carbon tsawg uas tsis tshua muaj txhij rau embrittlement thiab rhiab nyob rau hauv kev siv.
Hais txog N089262626262626262626262626 ensing ntxeem, turnine, roj compressor, iav thawv thiab lwm yam.
Pob tw weld fittings muaj nyob rau raws li luj tshib, Tees, lub kaus mom, reducers thiab tawm tawm (Olets). Cov fittings yog hom yeeb nkab ntau tshaj plaws ntawm Welded cov yeeb nkab fittings thiab tau teev los ntawm nominal cov yeeb nkab loj thiab cov khoom siv yeeb nkab. ButtWeld fittings siv seamless lossis welded yeeb nkab raws li cov txheej txheem pib thiab raug rho tawm ntawm cov txheej txheem ntawm lub sijhawm) kom tau txais cov txheej txheem ntawm lub sijhawm) kom tau txais cov txheej txheem ntawm lub sijhawm) kom tau txais cov txheej txheem ntawm lub sijhawm) kom tau txais cov txheej txheem 160, pob tw Weld cov yeeb nkab fittings tau muag tib txoj kev. Welded pob tw Weld fittings muaj ntau dua hauv cov hlau stainless vim muaj nqi zoo dua. Sch 10 fittings kuj tseem muaj ntau dua nyob rau hauv stainless hlau pob tw wandd fittings.
