ASTM A213 TP321 U-Tube rau Kub Exchangers
Tso lus
GNEE, raws li tus kws tshaj lij ntawm stainless hlau U-khoov hlab, muab TP321 (UNS S32100) titanium-stabilized austenitic stainless hlau U- raj kub exchanger tubes ua raws li ASTM A213 / SA213M thiab ASME cov khoom lag luam zoo{19. TP321 seamless raj, uas dhau los daws cov annealing (ceev txias los ntawm 920-1150 degree) los xyuas kom meej qhov zoo corrosion kuj. Tag nrho U-khoov seem raug rau qhov tsis siv neeg qhov kub thiab txias- tswj kev kho kev ntxhov siab, tiv thaiv kev cuam tshuam ntawm intergranular corrosion rhiab heev los ntawm kev kho cua sov. Phab ntsa thinning tus nqi nyob rau hauv qhov khoov cheeb tsam yog tswj nyob rau hauv tsawg dua los yog sib npaug zos rau 10%, thiab ovality nruj me ntsis raws li ASME B16.49 yuav tsum tau.
ASTM A213 TP321 U-Tube Manufacturing txheej txheem
Txuas nrog yog qhov kev ntxhov siab -relieving kho cua sov nkhaus rau peb 321 stainless hlau U- khoov.
TP321 stainless hlau U- raj kub exchangers muab kev txhim kho zoo siab - kub siab rupture lub zog thiab creep kuj piv rau 304 stainless hlau. Lawv tuaj yeem ua haujlwm ruaj khov nyob rau hauv ntev - lub sij hawm siab - qhov kub thiab txias ib puag ncig xws li 427-816℃(800-1500 ° F), ua rau lawv tshwj xeeb tshaj yog tsim rau cov cua sov sib hloov nrog kev caij tsheb kauj vab ntau zaus.
Peb muab 321 SS U- khoov hlab nrog ib txoj kab uas hla ntawm Φ6 hli mus rau Φ76.2 hli (NPS 1/4 "mus rau 3"), thiab phab ntsa thickness ntawm 1.0 hli mus rau 10 hli. Lub vojvoog dabtsi yog khoov (R) tuaj yeem hloov kho raws li qhov xav tau ntawm cov khoom siv hluav taws xob sib txawv. Qhov ncaj ntev ua ntej khoov tuaj yeem ncav cuag li 30 meters, nrog rau kev txiav txiav raws li kev thov.
Txhua pawg yog muab nrog EN 10204 3.1 daim ntawv pov thawj khoom. Raws li kev thov, peb tseem tuaj yeem muab cov ntaub ntawv ntsuas hydrostatic (feem ntau qhov ntsuas siab ntau dua lossis sib npaug li 1.5 npaug ntawm lub zog tsim), nrog rau kev ntsuas tam sim no (ET) lossis kuaj ultrasonic (UT) cov lus ceeb toom kom ntseeg tau tias muaj teeb meem - pub dawb. Cov khoom ua tau raws li PED 2014/68/EU thiab ASME Tshooj VIII siab hlab ntsha codes.
