- Squareness kam rau ua (sab nyob ib sab): Qhov siab tshaj plaws tso cai sib txawv 2 degree
Ntau qhov chaw tiav kev xaiv kom tau raws li ntau yam kev xav tau
- Dub (liab / oiled) + anti- xeb roj (tus qauv xa khoom)
- Tua- tawg
- pleev xim rau
- Kub-dip galvanized (HDG) (35-100 μm)
- Ua ntej-galvanized
ASTM A500 VS ASTM A501
- ASTM A500 npogtxias - tsimwelded thiab seamless carbon steel structural tubing (SHS / RHS / CHS), qhov nrov tshaj plaws hollow seem txheem rau North American kev tsim kho.
- ASTM A501 qhiakub- tsimwelded thiab seamless carbon steel structural tubing, feem ntau yog siv rau hnyav -lub luag hauj lwm infrastructure nrog tsawg lub lag luam muaj.
Lub rooj sib piv
| Yam khoom | ASTM A500 (Cold-Tsim) | ASTM A501 (Kub-Tsim) |
|---|---|---|
| Txheej txheem ntau lawm | Tsim ntawm ambient kub | Tsim nyob rau hauv qhov kub thiab txias |
| Kev lag luam nrov | Dominant, txaus Tshuag | Tsawg thov, feem ntau yog kev cai txiav txim |
| Standard Qib | Qib B (46 ksi), Qib C (50 ksi) Cov khoom siv hluav taws xob sib txawv ntawm qhov sib npaug & square / square | Qib A (35 ksi), Qib B (40 ksi), Qib C (50 ksi) Uniform mechanical xav tau rau txhua qhov duab |
| Residual Stress | Cold forming tsim cov kev ntxhov siab seem | Kev kub siab - kub ua kom tshem tawm cov kev ntxhov siab, zoo dua ductility thiab weldability |
| Dimensional kam rau ua | nruj kam rau ua; Sab nrauv lub vojvoog Tsawg dua lossis sib npaug li 3 × phab ntsa thickness | Ntau qhov kam rau ua; tsis muaj kev txwv nruj ntawm kaum lub vojvoog |
| Surface condition | Smooth nto, zoo tagnrho rau nthuav architectural Cheebtsam | Kub dov dub nplai, rougher nto |
| Kev txwv loj | Txwv qhov siab tshaj plaws perimeter | Txhawb ntxiv -loj & hnyav- phab ntsa hollow seem |
| Daim ntawv thov | Lub tsev thav duab, kab, facades, kev txhawb nqa brackets, machinery bases, hnub ci qauv | Cov choj, cov qauv thauj khoom hnyav, qis- cov haujlwm kub, cov khoom siv thauj khoom hnyav |
Xaiv ASTM A500 yog tias koj xav tau:
- General coj mus muag thiab vaj tse steel qauv
- Exposed architectural ntsiab nrog nruj zoo li yuav tsum tau
- Precise dimension tswj
- Static load daim ntawv thov nyob rau hauv ib txwm kub
- Lub sijhawm ua khoom lag luam nrawm thiab siv tau cov khoom lag luam
Xaiv ASTM A501 yog tias koj xav tau:
- Heavy infrastructure thiab kev tsim choj
- Tsawg- qhov kub thiab txias ib puag ncig lossis dynamic cuam tshuam loads
- Ntxiv - qhov loj thiab hnyav phab ntsa tuab
- Superior toughness, cuam tshuam tsis kam thiab vuam kev ua tau zoo
FAQ
Q: Kuv yuav xaiv qib twg, Qib B lossis Qib C?
A: Qib B yog qhov kev xaiv nrov tshaj plaws rau kev tsim kho. Qib C nta lub zog tawm los ntau dua, haum rau hnyav- lub luag haujlwm, seismic thiab choj qauv.
Q: Cov ntaub ntawv dab tsi koj tuaj yeem muab rau kev lis kev cai thiab kev tshuaj xyuas qhov project?
A: Peb muab EN 10204 3.1 MTC raws li tus qauv. EN 10204 3.2 thiab thib peb-cov ntaub ntawv tshuaj xyuas tog muaj nyob rau ntawm qhov kev thov.
Q: Puas yog ASTM A500 tib yam li ASTM A53 steel yeeb nkab?
A: Tsis yog. ASTM A53 yeeb nkab yog tsim los rau kev thauj mus los. ASTM A500 yog tsim tshwj xeeb rau cov khoom siv thauj khoom-cov hom phiaj thiab yuav tsum tsis txhob sib xyaw.
Q: ASTM A500 Square Box Tshooj yog dab tsi?
A: ASTM A500 Square Box Section, tseem hu ua Square HSS (Square Hollow Section), yog txias - tsim welded los yog seamless carbon steel structural tubing engineered rau load- bearing daim ntaub ntawv, dav siv nyob rau hauv North American kev tsim kho thiab mechanical engineering. Nws ua raws li ASTM A500 / A500M specification.
