Cov Lus Qhia Tshwj Xeeb
| tus qauv | Qhov siab (nti / hli) | Koojtooj dav (nti / hli) | Belly tuab (hli) | Wing Thickness (hli) | Theoretical hnyav (kg / m) | Tshooj Modulus SX (mping) |
|---|---|---|---|---|---|---|
| W21x50 | 21/533 | ~8.25/210 | Ntau dua los yog sib npaug rau 10 | Ntau dua los yog sib npaug rau 18 | 74 | ~1200 |
| W21x55 | 21/533 | ~8.25/210 | Ntau dua los yog sib npaug rau 12 | Ntau dua los yog sib npaug rau 20 | 82 | ~1400 |
| W21x57 | 21/533 | ~8.25/210 | Ntau dua los yog sib npaug rau 12 | Ntau dua los yog sib npaug rau 22 | 85 | ~1500 |
Cov yam ntxwv ua tau ntawm H Tshooj Hlau
Lub zog siab thiab lub tensile muaj zog yog {}} mpa mpa kom zoo dua li cov khoom siv tau los ntawm 15% {}}%.
Vim yog cov flanger tuab thiab webs, sx) ntawm w21x55 thiab 25% siab dua li ntawm W21X50, ntsig txog, thiab yog qhov tsim nyog rau cov khoom lag luam siab dua.
Corrosion Kuj: cov txheej txheem dab tsi ({580-620 degree) rov qab cov nplej thiab cov kab xeb tsis zoo rau cov qauv ntsev zoo dua li ntawm cov roj carbon steel.
Ua cov ntsiab lus hloov tau: nws txhawb cov nplaim taws / ntshav txiav, txias rau {{2} qib tuab ntau dua los yog sib npaug 25 hli). Dynamic bearer muaj peev xwm: tsawg cua cuam tshuam todlemness (ntau dua lossis sib npaug ntawm 18%
Cov chaw thov ntawm cov hlau H nqaj
W21X50 h zoo li tus hlau: nruab nrab lock: kab teeb nruab nrab ntawm cov nroj tsuag theem nrab ntawm kev siv cov nroj tsuag, cov khoom sib tw cov khoom sib tw), tsom mus rau kev lag luam thiab kev tsim kho sai.
W21x55 hiab Tus Qauv: Core Tube txhawb nqa vaj tse ntawm high-lub nqaj ntawm cov choj loj, ntsuas lub zog thiab tus nqi.
W21x57 hect nqaj: Loj Ntiv cov qauv (xws li ru tsev trusses ntawm cov chaw ua yeeb yam ntawm chaw ua yeeb yam), yuav tsum tau tiv thaiv kev cuam tshuam ntau ntawm cov khoom lag luam siab.
