ASTM A192 (ASME SA192) cov yeeb nkab hlau yog cov yeeb nkab carbon steel seamless siv rau hauv qhov kub thiab txias thiab siab siab thiab siv dav hauv boilers thiab cov cua sov sib pauv.
Txoj kab uas hla sab nraud: 1/2″ – 7″ (12.7 mm – 177.8 mm);
Phab ntsa tuab: 0.085″ – 1.000″ (2.2 hli – 25.4 hli);
Lwm qhov loj ntawm cov yeeb nkab hlau kuj tseem tuaj yeem muab tau raws li qhov xav tau, muab tias txhua yam kev cai ntawm A192 tau ua tiav.
ASTM A192 yog tsim los ntawm kev siv cov txheej txheem seamless thiab yog kub-tiav lossis txias-tiav raws li qhov xav tau;
Tsis tas li ntawd xwb, qhov kev txheeb xyuas cov yeeb nkab hlau yuav tsum qhia seb cov yeeb nkab hlau puas yog ua tiav kub lossis ua tiav txias.
Kub tiav: Hais txog cov txheej txheem ntawm kev ua tiav qhov ntev kawg ntawm lub raj hlau hauv lub xeev kub. Tom qab lub raj hlau tau dhau los ntawm cov txheej txheem ua tiav kub xws li dov kub lossis kos duab kub, nws tsis raug ua tiav txias ntxiv. Cov raj hlau kub tiav lawm muaj kev tawv thiab ductility zoo dua tab sis muaj kev kam rau siab loj.
Txias tiav lawmCov yeeb nkab hlau raug ua tiav mus rau nws qhov loj kawg los ntawm cov txheej txheem ua haujlwm txias xws li dov txias lossis kos duab txias ntawm chav tsev kub. Cov yeeb nkab hlau txias tiav lawm muaj qhov ntev dua thiab cov nplaim du dua tab sis yuav txo qee qhov tawv.
Cov kav hlau tsis muaj seamless uas kub tiav lawm tsis tas yuav kho cua sov.
Cov kav hlau tsis muaj qhov txuas uas txias lawm raug kho cua sov ntawm qhov kub ntawm 1200 ° F [650 ° C] lossis siab dua tom qab kev kho mob txias kawg.

Tshwj tsis yog teev tseg lwm yam hauv ASTM A192, cov ntaub ntawv muab los ntawm cov lus qhia no yuav tsum ua raws li cov kev cai ntawmASTM A450/A450M.
Rockwell Hardness: 77HRBW.
Rau cov kav hlau uas muaj phab ntsa tuab tsawg dua 0.2" [5.1 mm].
Brinell Hardness: 137HBW.
Rau cov yeeb nkab hlau uas tuab ntawm 0.2" [5.1 mm] lossis ntau dua.
Yog xav paub txog cov kev cai tshwj xeeb rau kev ua haujlwm, saib ASTM A450, Yam 23.
· Zaus: Txhua lub yeeb nkab hlau raug kuaj xyuas qhov siab hydrostatic.
· Lub Sijhawm: Khaws qhov siab tsawg kawg nkaus rau tsawg kawg 5 vib nas this.
· Tus nqi ntawm lub zog dej: Xam siv cov mis hauv qab no. Sau lub unit.
Nti - Phaus Chav: P = 32000 t/D
Chav SI: P = 220.6t/D
P = hydrostatic test pressure, psi lossis MPa;
t = teev tseg phab ntsa tuab, hauv. lossis hli;
D = teev tseg sab nraud txoj kab uas hla, hauv. lossis mm.
· Txiaj Ntsig: Yog tias tsis muaj qhov xau hauv cov kav dej, qhov kev sim ntawd suav tias tau dhau lawm.
Lwm txoj hauv kev rau kev sim hydrostatic kuj ua tau nrog kev sim tsis ua puas tsuaj.
Txawm li cas los xij, tus qauv tsis tau teev tseg tias yuav siv txoj kev sim uas tsis ua puas tsuaj li cas.
Cov raj xa dej thaum muab tso rau hauv lub boiler yuav tsum sawv ntsug nthuav dav thiab beading yam tsis muaj qhov tawg lossis qhov tsis zoo. Cov raj xa dej Superheater thaum tswj hwm kom zoo yuav tsum sawv ntsug txhua qhov kev forging, vuam, thiab khoov ua haujlwm tsim nyog rau daim ntawv thov yam tsis muaj kev tsim cov qhov tsis zoo.
