TP347H-stabilized ntsiab (xws li titanium los yog niobium) austenitic stainless hlau muaj welded kav

TP347H Stainless hlau welded yeeb nkab yog tshwj xeeb austenitic stainless hlau cov khoom, nws belongs rau lub thermal zog steel series, nrog zoo thermal stability thiab intercrystalline corrosion kuj. Cov khoom no yog tshwj xeeb tshaj yog haum rau siv nyob rau hauv high kub, xws li nyob rau hauv boiler superheater raj, reheater raj, chav kav dej, thiab petrochemical tshav kub exchangers. TP347H Zoo vuam kev ua tau zoo ntawm stainless hlau welded yeeb nkab, uas tso cai rau nws tswj cov khoom ruaj khov thiab corrosion kuj thaum lub sij hawm tsim khoom.

cov khoom paub meej

TP347H Nta ntawm stainless hlau welded yeeb nkab muaj xws li:

Thermal zog: nws tseem tuaj yeem tswj cov khoom zoo ntawm qhov kub thiab txias.

Kev tiv thaiv rau intercrystalline corrosion: los ntawm kev ntxiv niobium (Nb) ua tus stabilizer, intercrystalline corrosion yog zoo tiv thaiv.

Corrosion kuj: nws qhia tau hais tias zoo corrosion kuj nyob rau hauv alkaline, seawater thiab ntau yam acidic ib puag ncig.

Vuam kev ua tau zoo: haum rau cov txheej txheem vuam, tuaj yeem ua kom zoo thiab kev ncaj ncees ntawm cov vuam.

Nyob rau hauv cov nqe lus ntawm daim ntawv thov, TP347H stainless hlau welded yeeb nkab yog dav siv nyob rau hauv lub generator teeb, boiler superheater raj, reheater tube, chav yeeb nkab thiab petrochemical tshav kub exchanger thiab lwm yam kub thiab kub siab ib puag ncig. Tsis tas li ntawd, nws yog qhov tsim nyog rau cov xwm txheej antioxidant, nrog rau nws qhov tso cai antioxidant kub txog 750 ℃.

Thaum xaiv thiab siv TP347H stainless hlau welded kav, cov khoom ua tau raws li cov qauv thoob ntiaj teb, xws li ASTM A213 thiab ASTM A312, uas qhia meej txog cov tshuaj muaj pes tsawg leeg, cov khoom siv thiab cov txheej txheem tsim khoom. Tsis tas li ntawd, vim nws daim ntawv thov cov yam ntxwv ntawm qhov kub thiab txias, nws tseem ceeb heev uas yuav tsum xaiv txoj kev vuam tsim nyog thiab cov khoom siv vuam kom ntseeg tau qhov zoo ntawm cov vuam seam thiab durability ntawm tag nrho cov qauv.
