Qhov txawv ntawm ASTM A213 thiab A269 stainless hlau raj
Qhov txawv ntawm ASTM A213 thiab A269 stainless hlau raj
ASTM A213 tus qauv siv rau seamless alloy raj siv nyob rau hauv siab -kub / siab- siab ib puag ncig (boilers, heat exchangers) thiab qhia qhov tsawg kawg nkaus phab ntsa thickness; thaum tus qauv ASTM A269 npog seamless los yog welded austenitic stainless hlau hlab nrog rau corrosion kuj siv nyob rau hauv ntau yam kub thiab siv ib tug nruab nrab phab ntsa thickness. Yog li ntawd, tus qauv A213 yog qhov nruj dua rau qhov tseem ceeb, siab - kev siv kev ntxhov siab, thaum A269 tus qauv muaj kev hloov pauv ntau dua (tsis muaj seamless / welded, lub hom phiaj dav dav).
ASTM A213 khoom yog dab tsi?
ASTM A213 / ASME SA213 tus qauv npog qis- cov hlau alloy steel thiab seamless ferritic thiab austenitic steel boiler hlab, superheater raj, thiab austenitic steel tshav kub exchanger tubes nrog tsawg kawg nkaus phab ntsa thickness. Qib muaj xws li TP304, TP304H, TP304L, TP310S, TP310HCbN, TP316, TP316H, TP316L, thiab lwm yam.
ASTM A213 stainless hlau raj yog seamless raj ua los ntawm ferritic los yog austenitic stainless hlau, haum rau siab - kub thiab siab - kev siv siab.
Gnee Steel tsim cov raj no siv seamless lossis hluav taws xob fusion vuam (EFW) txoj kev. Tom qab ntawd lawv tau txais kev kos duab txias thiab nruab nrab annealing kom ua tiav cov txheej txheem microstructure thiab lub zog. Thaum kawg shaping yog ua raws li tag nrho annealing los txhim kho lub raj ductility, ua kom yooj yim rau khoov thiab flare thaum lub sij hawm installation.
Kev lag luam kev lag luam xav tau tsawg kawg ntawm phab ntsa thickness kam rau ua rau ASTM A213 raj. Lawv yog cov tsim nyog rau qhov nyuaj thermal ib puag ncig, xws li lub zog tsim hluav taws xob, petrochemical, thiab refining systems. Cov qib muaj xws li 304, 304L, 316, 316L, 321, 347, thiab lwm yam cua sov-resistant stainless hlau.
Cov kws tsim khoom siv ASTM A269 tus qauv hauv kev tsim cov hlau tsis muaj steel tubing (ob leeg seamless thiab welded). Cov hlab no muaj cov phab ntsa tuab tuab, muab kev yooj yim dua rau kev siv dav dav - siv thiab siv xws li qhov kub thiab txias.
Kev lag luam siv ASTM A269 tubing feem ntau tsom rau nws cov corrosion kuj, oxidation tsis kam, thiab huv. Cov yam ntxwv no ua rau nws tsim nyog rau kev siv tshuaj lom neeg, khoom noj khoom haus thiab dej haus, thiab tshuaj. Txhawm rau rov ua kom muaj kev tiv thaiv corrosion tom qab ua haujlwm txias, cov tubing tau txais kev kho cua sov thiab yog ci ntsa iab los yog pickled nyob ntawm qhov yuav tsum tau ua tiav.

ASTM A213 Seamless Tubes
Qauv: Seamless raj nkaus xwb.
Daim ntawv thov: Haum rau siab - kub thiab siab - cov kev mob siab, xws li boilers, superheaters, thiab cua kub exchangers.
Phab ntsa Thickness: Qhia qhov tsawg kawg nkaus phab ntsa thickness (piv txwv li, +20%, -0%) kom ntseeg tau cov qauv kev ncaj ncees.
Nto: Feem ntau muaj npub tiav vim kev tsim khoom (hluav taws xob tsis kam vuam).
ASTM A269 Seamless thiab Welded Tubes
Structure: Muaj nyob rau hauv ob qho tib si seamless thiab welded raj xaiv.
Daim ntaub ntawv: Haum rau kev tiv thaiv corrosion, qis / siab- qhov kub thiab txias (cov cuab yeej, tshuaj, thiab khoom noj khoom haus kev lag luam).

Kev tsim khoom
Cov txheej txheem tsim khoom rau ob hom yeeb nkab txheem suav nrog qee cov kauj ruam, xws li kos duab txias thiab annealing. Cov neeg tsim khoom siv kev kho cua sov ntxiv thiab ntsuas qhov ntsuas kom ntseeg tau tias muaj kev ruaj khov thiab ruaj khov ntawm ASTM A213 cov kav dej nyob rau hauv lub caij ntuj sov.
Hauv qhov sib piv, ASTM A269 cov kav dej yog tsim los siv hnyav heev - ua haujlwm welded tubing, uas tso cai rau cov tuam txhab tsim cov kav dej nrog lub ntsej muag du, uas yog qhov zoo tshaj plaws rau kev thauj cov dej.
Ob hom yeeb nkab yog capped tom qab annealing kawg thiab tu. Cov kev ntsuas no yog npaj los tiv thaiv kev kis kab mob thaum caij tsheb thauj mus los.
Phab ntsa Thickness kam rau ua
Cov neeg tsim khoom txiav txim siab phab ntsa thickness kam rau ua raws li cov yeeb nkab sab nraud. Cov ntaub ntawv ntsig txog qhia tias qhov tsawg kawg nkaus phab ntsa thickness kam rau ua rau ASTM A213 yog ± 20% rau ± 22% ntawm phab ntsa tuab. Raws li kev lag luam txhim khu kev qha, phab ntsa thickness kam rau ua rau ASTM A269 yog -10% rau -15%, nyob ntawm seb cov yeeb nkab loj.
Yuav xaiv li cas:
Rau cov siab tseem ceeb-cov khoom siv hauv cov boilers lossis cov khoom siv hluav taws xob, qhov uas tsis ua haujlwm yuav muaj qhov tshwm sim loj, siv A213 cov ntaub ntawv txheem.
Rau cov kav dej dav dav, kev ntsuas, lossis thaum cov qauv welded tau txais raws li tus nqi / qhov loj, siv A269 cov ntaub ntawv txheem.
