1. Cov Ntaub Ntawv: 1.0345 (EN 10216-1 P235GH)
Tus lej1.0345yog tus lej xov tooj los ntawm European txheemEn 10216-1, uas npog seamless cov yas rau lub siab lub hom phiaj.
Qhov sib npaug ntawm cov npe qib steel yogP235GH.
Cia peb txiav plaub lub npe:
P: Sawv rau "siab" lub hom phiaj.
235: Qhia txog tusYam tsawg kawg nkaus xwb Zog(Reh) nyob rau hauv chav tsev kub yog 235 MPa (megapStascals). Qhov no yog kev ntsuas ntawm kev ntxhov siab cov hlau tuaj yeem tiv taus yam tsis muaj kev cuam tshuam tas li.
G: Sawv rau "Grain" ua kom zoo.
H: Qhia tias nws yog qhov haum rausiab - kubkev pabcuam.
Cov yam ntxwv tseem ceeb ntawm P235GH / 1.0345:
Daim Ntawv Thov:Feem ntau siv rau cov hlab ntsha siab, boilers, kev hloov cua sov, thiab siab {{} Cov nroj tsuag kub} pa roj, tshuaj lom neeg).
Khoom:Zoo weldability, kev ua kom zoo txias ua cov khoom, thiab ruaj khov kho cov khoom siv thaum nce kub (feem ntau txog ~ 350 degree).
Hloov pauv hloov / sib npaug:
Tebchaws Asmeskas (ASTM):ASTM A106 Grade B, ASTM A53 Grade B (for certain applications), ASTM A192 (for high-pressure boiler tubes).
Lub teb chaws Yelemees (Din):Yav tas los muaj st35.8.
2. Cov txheej txheem tsim khoom: Seamless yeeb nkab
A Seamless Steel Yeeb Nkabyog tsim los ntawm ib qho khoom muag cylindrical hlau billet.
Yuav ua li cas nws ua (luv luv):
Ib lub hnab ntim khoom yog rhaub rau qhov kub.
Ib tus pas nrig xaiv tau raug yuam los ntawm lub chaw kom tsim lub ntsej muag khoob "."
Lub plhaub no yog elongated thiab dov hla lub mandrel kom ua tiav cov kab uas xav tau, phab ntsa tuab, thiab ntev.
Cov Ntsiab Lus Zoo ntawm Seamless Kav:
Tsis muaj Welded Seam:Cov yeeb nkab muaj cov qauv homogeneous nyob ib ncig ntawm nws txoj kev ncig. Qhov no tshem tawm ib qho kis tau qhov tseem ceeb.
Kev Ntsuas Siab Siab Tshaj:Vim tias tsis muaj nqaws, lawv feem ntau tuaj yeem tiv thaiv kev nce sab hauv thiab sab nraud.
Cov ris tsho sib luag:Ntau txuas phab ntsa tuab thiab lub zog faib.
Kev ntseeg tau:Nyiam rau cov ntawv thov tseem ceeb uas muaj kev kub siab, kub, lossis cov tshuaj ua kom huv.
Ntsiab lus: 1.0345 seamless steel yeeb nkab
Muab nws ua ke, a1.0345 seamless steel yeeb nkabyog:
Lub siab - Zoo, Welded - Dawb raj tau ua los ntawm lub siab dawb ntawm lub siab thiab nce qhov kub.
Cov lus qhia raug rau kev txiav txim
Thaum xaj cov yeeb nkab no, koj yuav xav tau qhia:
Txheem:En 10216-1
Khoom siv:1.0345 (P235GH)
Txheej txheem tsim khoom:Tsis ntse
Qhov loj me:
Sab nraud inch (OD):Xws li, 21.3 mm, 33.7 hli, 114.3 mm, 323.9 mm (lossis hauv ineches)
Phab ntsa tuab (wt):Xws li, 2.6 hli, 3.2 hli, 6.3 hli, 8.6 hli (feem ntau teev raws li "sijhawm," zoo li Sch 40, Sch 80)
Ntev:Random lossis taag ntev (piv txwv li, 6 meters, 12 meters).
Cov Kev Siv Cov Ntawv Siv
Lub zog tiam:Cov kab ncu, xaim leeg, kab.
Roj & Roj:Kev tsim cov kav dej, sib sau ua ke kab.
Tshuaj lom neeg & cov nroj tsuag petrochemical:Txheej txheem piping rau corrosive thiab siab - siab med media.
Cua sov Systemsiab:Rau siab -} Lub Cheeb Tsam Kev Siv Hluav Taws Kub.
Hauv ntej, yog tias koj pom "1.0345 seamless steel yeeb nkab," Koj tab tom saib lub zog, txhim khu kev qha yeeb nkab tsim rau kev siv cov ntawv thov kev lag luam siab.
