Dab tsi yog cov qib ntawm ASTM A500 structural welded yeeb nkab?
Cov qhab nia ntawm ASTM A500 structural welded yeeb nkabyog A, B, C, thiab D. Cov qhab nia no raug cais raws li lawv cov khoom siv tshuab.
Dab tsi yog qhov zoo thiab cov yam ntxwv ntawm ASTM A500 welded yeeb nkab?
ASTM A500 welded yeeb nkabmuaj lub zog zoo heev - rau - qhov hnyav piv, ua rau nws zoo tagnrho rau kev thauj khoom - cov ntawv thov hauv kev tsim kho thiab kev tsim kho vaj tse. Nws lub ntsiab zoo muaj xws li siab weldability, zoo machinability, txias formability, thiab zoo heev nto tiav.
Hauv cov teb twg yog ASTM A500 cov qauv welded yeeb nkab siv?
A500 steel yeeb nkabyog qhov zoo tagnrho rau ntau qhov kev tsim kho. Nws lub zog siab thiab ua haujlwm ntev tso cai rau nws tiv taus ib puag ncig hnyav, huab cua huab cua, thiab lwm yam tshwj xeeb hauv koj daim ntawv thov.A500 steel yeeb nkabfeem ntau yog siv rau hauv kev tsim kho ntawm:
Cov choj
Cov tsev
Skeletal txhawb nqa thiab framing rau tej yaam num ntawm txhua qhov ntau thiab tsawg
Welded, riveted, los yog bolted lug
Chav dej, dej, thiab cua xa cov tshuab
Yuav txiav txim qhov zoo ntawm ASTM A500 structural welded steel yeeb nkab li cas?
Txhawm rau txiav txim siab qhov zoo ntawmASTM A500 welded steel yeeb nkab, txheeb xyuas nws cov khoom siv hluav taws xob (lub zog tensile thiab lub zog tawm los), ua cov kev ntsuas ductility thiab flattening, thiab xyuas seb qhov ntev ntev npaum li cas.
Yuav ua li cas xaiv ASTM A500 structural welded steel yeeb nkab?
Xaiv kom haumASTM A500 welded steel yeeb nkab, ua ntej txiav txim siab txog daim ntawv thov ntawm qhov project, tom qab ntawd xaiv cov qib uas tsim nyog (Qib B lossis C) thiab cov duab (puab, square, lossis duab plaub) raws li qhov yuav tsum tau muaj zog. Thaum kawg, qhia qhov tseeb qhov ntev (sab nraud txoj kab uas hla thiab phab ntsa thickness) thiab tej yam uas xav tau kev kho deg los yog txheej txheej.
