Nkag siab txog ASTM A500 Specification
Kev nrhiav cov raj tsim nyog yuav tsum muaj kev nkag siab meej ntawm cov khoom siv hlau thiab cov ntsuas ntsuas uas tau teev tseg los ntawm American Society for Testing and Materials (ASTM):
- Qhov Txias -Kev Ua Tau Zoo:ASTM A500 raj yog txias-tsim los ntawm tiaj- dov steel strips thiab welded longitudinally siv High-Frequency Induction (ERW) technology. Txias txoj kev ua kom cov hlau tawm los thiab lub zog tensile los ntawm cov txheej txheem ntuj hu uaua hauj lwm hardening, ua rau ib tug nruj heev qauv nrog ib tug du, aesthetically pleasing nto zoo tagnrho rau nthuav architectural daim ntaub ntawv.
- Qib B & C kev sib cais (Qib B & C):Cov kev qhia tshwj xeeb tau muab faib ua cov khoom sib txawv, nrog Qib B thiab Qib C yog cov qauv kev lag luam:
- Qib B:Cov qauv ntsuas ib txwm muaj, muab cov txiaj ntsig zoo zog (txog 317 MPa (46,000 psi) rau cov raj zoo li qub).
- Qib C:Ntau dua - kev tsim muaj zog muab txog li 345MPa (50,000psi) tawm lub zog, tso cai rau cov kws ua haujlwm kom txo cov phab ntsa tuab thiab txuag tag nrho cov hlau tonnage yam tsis muaj kev cuam tshuam cov qauv kev thauj khoom.
Core Geometric Profiles
ASTM A500 1steel hlab yog tsim nyob rau hauv peb lub hauv paus duab kom haum raws li qhov sib txawv ntawm cov txheej txheem engineering:
1. Square Hollow Sections (SHS)
Featuring sib npaug sab qhov ntev thiab symmetrical cross-sections, square ASTM A500 raj muab cov yam ntxwv tsis sib xws rau compression thiab buckling raws ob lub axes. Lawv tau dav siv los ua cov kab ke thiab cov ncej.
2. Rectangular Hollow Sections (RHS)
Nrog rau qhov sib txawv axis muaj zog thiab tsis muaj zog axis, cov raj duab plaub yog qhov zoo rau kev siv khoov. Lawv ua haujlwm zoo li cov kab teeb pom kev zoo, cov joists, thiab cov cav ntoo hla - cov tswv cuab uas cov khoom siv feem ntau siv rau hauv ib qho kev taw qhia.
3. Round Hollow Sections (CHS)
Round A500 tubing muab zoo heev torsional (twisting) tsis kam thiab aerodynamic efficiency. Cov no feem ntau siv nyob rau hauv qhov chaw thav duab, tes tuav, truss tes hauj lwm, thiab zoo nkauj architectural pillars.
Technical Specifications: Qib thiab Mechanical Properties
ASTM A500 specification tau muab faib ua ntau qib (feem ntau yog Qib A, Qib B, Qib C, thiab Qib D). Ntawm cov no,Qib BthiabQib Cyog cov feem ntau thov nyob rau hauv kev lag luam thoob ntiaj teb vim lawv superior zog yam ntxwv.
Ntawm no yog ib qho kev tawg ntawm qhov tsawg kawg nkaus cov cuab yeej cuab tam raws li tus qauv:
| Profile Shape & Qib | Yam tsawg kawg Yield Strength | Yam tsawg kawg Tensile Strength | Tsawg kawg Elongation |
| Zoo li (Square / Rectangular) | |||
| Qib B | 46,000 psi (317 MPa) | 58,000 psi (400 MPa) | 23% |
| Qib C | 50,000 psi (345 MPa) | 62,000 psi (427 MPa) | 21% |
| Hloov Profiles | |||
| Qib B | 42,000 psi (290 MPa) | 58,000 psi (400 MPa) | 23% |
| Qib C | 46,000 psi (317 MPa) | 62,000 psi (427 MPa) | 21% |
Key Takeaway: Qib Cmuab cov txiaj ntsig siab dua thiab lub zog tensile piv rau Qib B, ua rau nws qhov kev xaiv zoo tshaj plaws rau cov phiaj xwm txhawm rau txo qis tag nrho cov hlau hnyav yam tsis muaj kev cuam tshuam cov qauv kev thauj khoom.
Cov lus nug nquag nug (FAQ)
Q: Dab tsi yog qhov siab tshaj plaws phab ntsa thickness muaj rau ASTM A500 tubing?
A: Raws li tus qauv ASTM, qhov siab tshaj plaws phab ntsa thickness rau txias - tsim A500 cov qauv tubing yog0.625 nti (15.88 hli). Yog tias koj qhov project xav tau cov phab ntsa tuab dua 5/8", koj yuav tsum tau saib rau hauv kub - tiav specifications xws li ASTM A106 lossis EN 10210.
Q: ASTM A500 tubing puas tuaj yeem kub -dip galvanized?
A: Yog, kiag li. Thaum nws yog tsim los nrog ib tug liab qab tiav, A500 steel tubing tuaj yeem kub siab -dip galvanized ncej- ntau lawm los yog coated nrog zinc- nplua nuj primer los muab ntau xyoo ntawm kev tiv thaiv xeb sab nraum zoov hauv corrosive lossis ntug dej hiav txwv ib puag ncig.
Q: Yuav ua li cas yog lub kaum sab xis radii xam rau square / rectangular A500 raj?
A: Rau qhov txias- tsim welded square thiab lub raj, lub kaum sab xis sab nraud feem ntau tsis tshajpeb npaug ntawm phab ntsa thickness ($ 3t$). Kev tuav lub kaum lub vojvoog meej yog qhov tseem ceeb rau kev ua kom haum zoo - nrog rau cov hlua txuas thiab cov ntsia hlau.
Q: Qhov txawv ntawm ASTM A500 thiab ASTM A513 yog dab tsi?
A: ASTM A500 1yog engineered tshwj xeeb raustructural thiab load-kev siv cov kabmob(lub tsev, txuas hniav, thav duab) thiab tuav cov txiaj ntsig tshwj xeeb, tensile, thiab kev ntsuam xyuas cuam tshuam.ASTM A513 Cov Lus Qhia Tshwj Xeebyog npaj raumechanical thiab ornamental kev siv(cov rooj tog zaum, cov khoom siv, cov khoom siv hauv tsheb) qhov kev ua kom zoo nkauj zoo nkauj thiab qhov ntev ntawm qhov kev ua siab ntev tseem ceeb tshaj qhov hnyav ntawm cov khoom siv.
