ASTM A210 Qib C (ASME SA210 Qib C) yog ib qho nruab nrab-carbon seamless steel raj tshwj xeeb tsim los siv rau hauv kev tsim cov boiler raj thiab boiler flues, nrog rau kev nyab xeeb kawg, rauv phab ntsa thiab cov hlab txhawb, thiab superheater raj.
Qib C muaj cov khoom siv zoo, nrog lub zog tensile ntawm 485 MPa thiab lub zog tawm los ntawm 275 MPa.Cov khoom no, nrog rau cov khoom siv tshuaj tsim nyog, ua rau ASTM A210 Qib C raj zoo siv rau hauv qhov kub thiab txias. Kev kub siab ib puag ncig thiab muaj peev xwm tiv taus cov kev kub ntxhov uas tsim los ntawm kev ua haujlwm boiler.
Cov raj yuav tsum tau ua los ntawm cov txheej txheem seamless thiab yuav tsum yog kub-tiav lossis txias-tiav.
Hauv qab no yog daim ntawv qhia khiav ntawm cov txheej txheem tsim khoom rau txias-tiav seamless steel yeeb nkab:
Yog li dab tsi yog qhov txawv ntawm kub-tiav thiab txias-tiav seamless steel yeeb nkab thiab koj xaiv li cas?
Kub-tiavseamless steel yeeb nkab yog cov yeeb nkab steel uas tau dov los yog pierced ntawm qhov kub thiab txias thiab lwm yam txheej txheem thiab ces txias ncaj qha mus rau chav tsev kub.Cov kav hlau hauv lub xeev no feem ntau muaj qhov zoo dua thiab muaj zog, tab sis qhov zoo ntawm qhov chaw yuav tsis zoo li cov kav dej txias txias vim tias cov txheej txheem kho cua sov tuaj yeem ua rau oxidation lossis decarburization ntawm cov yeeb nkab steel.
Txias-ua tiavseamless steel yeeb nkab yog hais txog kev ua tiav kawg ntawm cov yeeb nkab steel los ntawm kev kos duab txias, txias dov, thiab lwm yam txheej txheem ntawm chav tsev kub.Cold-finished steel yeeb nkab muaj qhov tseeb dua qhov tseeb, thiab qhov zoo ntawm qhov zoo, thiab vim tias kev ua haujlwm txias tuaj yeem txhim kho lub zog thiab tawv ntawm cov yeeb nkab steel, cov khoom siv ntawm cov yeeb nkab txias-tiav steel feem ntau zoo dua li cov yeeb nkab steel kub. .Txawm li cas los xij, qee qhov kev ntxhov siab nyob hauv yuav raug tsim tawm hauv cov yeeb nkab steel thaum ua haujlwm txias, uas yuav tsum tau muab tshem tawm los ntawm kev kho cua sov tom ntej.
Kub-tiav steel yeeb nkab tsis xav tau kev kho cua sov.
Cold-finished tubes yuav tsum yog subcritical annealed, tag nrho annealed, los yog ib txwm kub kho tom qab qhov kawg txias tiav txheej txheem.

Flattening Test
Kua muag los yog tawg tshwm sim ntawm 12 og 6 teev sawv ntxov ntawm Qib C tubing nrog qhov ntau thiab tsawg ntawm 2.375 in. [60.3 mm] nyob rau sab nraud thiab me dua yuav tsum tsis txhob suav tias yog lub hauv paus rau kev tsis lees paub.
Cov kev cai tshwj xeeb tuaj yeem pom hauvASTM A 450 1.5 hli,,nqe 19.
Flaring Test
Cov kev cai tshwj xeeb tuaj yeem pom hauv ASTM A450, yam 21.
Hardness
Qib C: 89 HRBW (Rockwell) lossis 179 HBW (Brinell).
Txhua cov yeeb nkab steel yuav tsum raug kuaj los ntawm hydrostatic siab los yog tsis muaj kev puas tsuaj hluav taws xob.
Hydrostatic ntsuas qhov ntsuas yuav tsum tau ua raws li ASTM 450, yam 24.
Cov kev sim uas tsis muaj kev puas tsuaj rau hluav taws xob yog raws li ASTM 450, yam 26.
Kev tsim ua haujlwm yog tsim nyog rau cov raj boiler kom ntseeg tau tias cov hlab ua tau raws li cov kev xav tau tshwj xeeb ntawm boiler system.
Thaum muab tso rau hauv lub boiler, cov hlab yuav tsum sawv expanding thiab beading yam tsis muaj kev sib tsoo los yog flaws.Thaum kho kom raug, cov raj superheater yuav tsum sawv tag nrho cov forging.vuam.thiab khoov cov haujlwm tsim nyog rau daim ntawv thov yam tsis muaj kev txhim kho.
