Dab tsi yog A500 Steel Yeeb Nkab?
Kev txhais thiab Txuj Ci
Siv cov qauv txheej txheem: Tsim khaub ncaws welded / seamless carbon hlau yeeb nkab, siv raws li ASTM A500 / A500M, muaj kev txhawb nqa-cov kab ke xws li kev tsim cov ntas thiab Choj kev txhawb nqa.
Qib Kawm Kawm Qib Kawm: A, B, C, thiab D, uas B yog cov feem ntau siv ntau dua lossis sib npaug ntawm 345MPA).
Yam ntxwv
Cov Khoom Siv Neeg Kho Tshuab
Qib B: Tso tawm lub zog ntau dua lossis sib npaug ntawm 345 MPa, tensile lub zog 420-550 mpa, elongation ntau dua lossis sib npaug rau 18%;
High-zog tsim qauv: D xav tau kev kho cua sov thiab ntxiv dag zog rau (kom meej lub zog ntau dua lossis sib npaug nrog 400 MPA).
Cov txheej txheem zoo: Zoo heev txias dabtsi yog khoov thiab weldability, haum rau cov txheej txheem ua.
Raug Siv Siv
Tsev ntaub thaiv phab ntsa npluav hluav taws xob, tshuab tsim khoom; Tsheb chaw tsheb ua haujlwm saib xyuas, cov haujlwm hnyav-txoj haujlwm txhawb nqa.
Dab tsi yog A252 steel yeeb nkab?
Kev txhais thiab Txuj Ci
Cov Pile Foundation Tsuas yog: Tsawg Carbon Welded / Seamless Steel Yeeb Nkab, ASTM A252, mob siab txhim tsa pawg Foundation thiab cov qauv kev txhawb nqa hauv av.
Qib Kev Kawm Tawm: Gr1, Gr2, Gr3, Gr3 lav lub zog ntau dua los yog sib npaug rau 310 mpa.
Yam ntxwv
Kev Tsim Kev Tsim: Cov pa roj carbon tsawg (C Tsawg dua li lossis sib npaug rau 0.26%), qis dua li 0.045%), optimized vuam thiab av corrosion tsis kam;
Cov Khoom Siv Neeg Kho Tshuab:
GR3 qib: tawm los lub zog ntau dua los yog sib npaug rau 310 mpa, tensile lub zog 420-550 mpa, elongation ntau dua los yog sib npaug rau 17%.
Raug Siv Siv
Sib sib zog nqus piles ntawm cov tsev siab siab, yeeb nkab pawg Port Portinals;
Kev pab txhawb ib ntus, tsev cog khoom ua liaj / teb Agricultural.
Dab tsi yog qhov sib txawv ntawm astm A500 thiab A252 yeeb nkab
| Kev sib piv qhov ntev | A500 STEEL YEEB | A252 Yeeb Nkab Hlau |
|---|---|---|
| Lub hom phiaj tseem ceeb | Saum av load-bearch qauv (pom qhov) | Underground Foundation Suplation (zais engineering) |
| Lub zog tsim | Lub zog siab dua (Qib B ntau dua lossis sib npaug rau 345 MPa) | Qhov tseem ceeb ntawm kev tawv (gr3 ntau dua lossis sib npaug rau 310 mpa) |
| Cov Khoom Siv Khoom Noj Muaj | Cov ntsiab lus manganese ntau dua (B Qib Mn tsawg dua lossis sib npaug rau 1.35%) | Cov pa roj carbon tsawg thiab tsis muaj zog (C tsawg dua lossis sib npaug rau 0.26%) |
| Cov Txheej Txheem Tus Nqi | Feem ntau cov txheej txheem txias tsim, tus nqi siab | Cov khoom xyaw yooj yim, 10-15% tus nqi qis dua |
| Ib puag ncig kev yoog | Cia siab rau txheej rau kev tiv thaiv corrosion (sab nraum zoov sab nraum zoov) | Ib txwm tiv taus av corrosion |
