ASTM A376

ASTM A376yog tus qauv kev tshwj xeeb rauSeamless Austenitic steel yeeb nkab rau high- kub chaw nres tsheb chaw nres tshebCov. Nws npog cov kav tsim los daws cov siab ua haujlwm thiab kub, ua rau lawv xaiv tseem ceeb rau cov khoom tseem ceeb li cov khoom siv hluav taws xob zoo li cov hluav taws xob cog qoob loo.

Tus qauv yog tshwj xeeb sau rau cov neeg xav tau ntawm "chaw nres tsheb hauv nruab nrab," uas ib txwm xa mus rau:

Lub zog tiam:Cov kab chav dej tseem ceeb, cov kab kev rov ua haujlwm hauv cov roj fossil thiab cov khoom siv hluav taws xob nuclear.

Cov tshuab hluav taws kub:Rau cov txheej txheem xav tau corrosion tsis kam thiab lub zog ntawm kev nce siab kub.

Superheaters thiab Boiler Tubes:Qhov twg cov khoom siv yuav tsum tawm tsam nkag (qeeb deformation nyob rau hauv kev ntxhov siab ntawm kev kub siab).

Txhua daim ntawv thovxav tau seamless austenitic stainless hlau kav hlau nrog tshwj xeeb high - kub cov khoom siv.

ASTM A376 / A376M npog ntau hom kev pheej hmoo ntawm cov qib stainless hlau me, nrog cov kev sib tw tshaj plaws:

TPP04H:Qib ua haujlwm rau siab -} qhov kev pabcuam kub thiab txias. Tus "H" txhais tau tias muaj cov ntsiab lus carbon ntau dua (0.04- 0,1%) rau kev txhim kho siab lub zog.

TP316H:Zoo ib yam li 304H tab sis nrog ntxiv ntawm Molybdenum kom zoo dua lub zog thiab corrosion tsis kam, tshwj xeeb tshaj tawm tsam chlorides.

TP321H:Degilized nrog titanium los tiv thaiv chomium carbide nag lossis daus thaum lub sij hawm vuam thiab kis tau cov kev ua rau muaj kev cuam tshuam ntau dua los inngranular.

TAPP37H:Ruaj khov nrog niobium (thiab qee zaum tantalum) rau kev tiv thaiv zoo rau intergranular corrosion thiab siab heev creep lub zog.

Lwm qib zoo li TPP32, thiab TP321, thiab TP321, thiab Tp347 (tsis yog} "H" nrog tsawg dua rau qhov tseem ceeb tshaj plaws- kub kev pab.

Seamless raug:Tag nrho cov yeeb nkab muab rau cov qauv no yuav tsum yog seamless, lub ntsiab lus nws raug chob los ntawm cov khoom noj khoom haus. Qhov no tshem tawm cov leeg veam ntev nrhiav hauv Welded Yeeb Nkab (zoo li ASTM A312), uas yog qhov muaj peev xwm ua tsis tiav ntawm kev ua tsis tiav.

High - cov khoom kub:Cov txheej txheem qhov chaw muaj zog rau cov khoom tseem ceeb ntawm qhov kub:

Lub Zog Txiaj Ntsig:Lub peev xwm los tawm tsam deformation ntev ntev nyob rau hauv kev ntxhov siab thiab kub kub.

Kev ntxhov siab ntxhov siab tawg:Lub peev xwm tiv thaiv kev txha lov hauv qab tas li thauj tau ntawm qhov kub.

Oxidation tsis kam:Kev tsim ntawm ib qho ruaj khov chromium oxide txheej uas tiv thaiv cov hlau los ntawm kev saib tsis taus ntxiv.

Kev kho cua sov (daws annealing):Tag nrho cov kav dej yuav tsum yog cov tshuaj tiv thaiv tshav ntuj (tov annealed) thiab nrawm nrawm los yaj thiab ua tiav homogeneous autenic. Qhov no yog qhov tseem ceeb rau kev ua kom loj hlob ntawm corrosion tsis kam thiab cov khoom siv mechanical.

Hydrostatic kuaj:Txhua cov yeeb nkab yuav tsum tau dhau ib qho tsis yog -} Despuctive hydrostatic kev sim. Qhov kev ntsuas siab yog suav rau kev ntxhov siab hauv cov yeeb nkab phab ntsa sib npaug ntawm cov feem pua ​​ntawm cov hlau yam tsawg kawg nkaus muaj zog.

Tsis - Kev Ntsuam Xyuas Kev Ntsuas (NDE):Tus qauv xav tau Eddy tam sim no lossis ultrasonic kuaj qhov tsawg kawg nkaus. Qhov no yog ua kom ntseeg tau sab hauv thiab sab nraud ntawm cov yeeb nkab thiab los kuaj xyuas txhua qhov tsis zoo uas tuaj yeem ua rau tsis ua haujlwm.

Tshuaj lom neeg muaj pes tsawg leeg tshuaj thiab cov neeg kho tshuab:Tus qauv muaj kev txwv nruj me me ntawm cov tshuaj muaj tshuaj lom neeg (carbon, chensile siv zog, elongation lub zog, elongation) kom ntseeg tau tias cov ntaub ntawv sib xws thiab ua haujlwm.
