txias-tsim welded thiab seamless carbon steel structural tubing nyob rau hauv round, square, thiab rectangular duab.Nws yog dav siv hauv kev tsim kho, kev tsim kho vaj tse, thiab kev siv tshuab vim nws lub zog-rau-hnyav piv thiab durability.
Qhov kev qhia tshwj xeeb no suav nrog ntau qib thiab qhov ntau thiab tsawg ntawm tubing, suav nrog cov qauv, nruab nrab, thiab qib siab zog. Nws kuj qhia txog cov tshuaj thiab cov khoom siv kho tshuab uas xav tau rau txhua qib, nrog rau cov txheej txheem tsim khoom thiab kev kam rau siab.
Nws yog tus qauv tseem ceeb hauv kev lag luam steel vim nws ua kom ntseeg tau tias cov tubing ua tau raws li qhov tsim nyog yuav tsum tau siv rau nws txoj kev npaj. Los ntawm kev ua raws li tus qauv no, cov tuam txhab tsim khoom tuaj yeem tsim cov raj zoo uas tiv taus corrosion, hnav thiab tsim kua muag, thiab lwm yam ib puag ncig.
Zuag qhia tag nrho, ASTM A500 plays lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb, kev ntseeg siab, thiab kev ua haujlwm ntawm cov qauv thiab cov khoom siv uas vam khom cov tubing steel. Nws yog ib qho txiaj ntsig zoo rau kev lag luam thiab pab tswj cov txheej txheem siab rau cov khoom zoo thiab kev ua haujlwm zoo.
ASTM A500 muaj ntau qib, txhua tus muaj lub zog sib txawv thiab lub zog tensile yam tsawg kawg nkaus.Cov qib no suav nrog Qib A, Qib B, Qib C, thiab Qib D.Qhov tsawg kawg nkaus tawm lub zog rau Qib A yog 39 ksi, Qib B yog 46 ksi, Qib C yog 50 ksi, thiab Qib D yog 50 ksi.
Txhua qib ntawm ASTM A500 tubing muaj cov khoom tshwj xeeb thiab tsim los rau cov ntawv thov tshwj xeeb. Piv txwv li, Qib A yog qhov zoo tagnrho rau cov qauv kev txhawb nqa thiab kev tsim kho dav dav, thaum Qib B zoo meej rau cov tsheb thauj khoom thiab cov thav ntawv.
ASTM A500 muaj ntau qib tsim los ua kom tau raws li kev tsim kho sib txawv. Nrog nws cov txiaj ntsig siab thiab lub zog tensile tsawg kawg nkaus, ASTM A500 yog qhov kev xaiv ruaj khov thiab ruaj khov rau txhua qhov kev tsim kho.
