Kev faib cov Qib
ASTM A501 tau muab faib ua peb qib, Qib A, Qib B, thiab Qib C.
Hollow Section Shapes
Square, round, rectangular, los yog cov duab tshwj xeeb.
Cov khoom siv raw
Cov hlau yuav tsum tau ua los ntawm theem pib - pa oxygen lossis hluav taws xob -arc- cub tawg steel - txheej txheem ua.
Cov hlau yuav raug cam khwb cia rau hauv ingots los yog strand cast.
Cov txheej txheem tsim khoom
Lub raj yuav tsum tau ua los ntawm ib qho ntawm cov txheej txheem hauv qab no: seamless; rauv- taub qab- vuam (nruam vuam); hluav taws xob kuj welding (ERW) los yog submerged arc vuam (SAW) ua raws li los ntawm reheating thoob plaws hauv tus ntoo khaub lig-section thiab kub sib sau los ntawm ib tug txo los yog shaping txheej txheem, los yog ob qho tib si.
Kev tsim cov duab kawg yuav tsum tau ua los ntawm cov txheej txheem kub txheej txheem.
Nws yuav tsum tau tso cai ntxiv ib qho kev kho cua sov rau cov tubing nrog phab ntsa thickness ntau dua 13 hli [1/2 hauv].
Tshuaj muaj pes tsawg leeg ntawm ASTM A501
Txoj Kev Xeem: ASTM A751.
astm a501 Chemical Requirements
Nyob rau hauv ASTM A501 tus qauv, muaj ob txoj kev tshuaj ntsuam rau cov tshuaj muaj pes tsawg leeg ntawm cov hlau: thermal tsom xam thiab cov khoom tsom xam.
Kev ntsuas cua sov yog ua thaum lub sijhawm melting ntawm cov hlau. Nws lub hom phiaj yog los xyuas kom meej tias cov tshuaj muaj pes tsawg leeg ntawm cov hlau ua tau raws li qhov yuav tsum tau muaj ntawm tus qauv tshwj xeeb.
Kev tshuaj xyuas cov khoom, ntawm qhov tod tes, yog ua tom qab cov hlau twb tau ua rau hauv cov khoom. Txoj kev tshuaj ntsuam no yog siv los xyuas kom meej tias cov tshuaj muaj pes tsawg leeg ntawm cov khoom kawg ua tau raws li qhov yuav tsum tau ua.
Mechanical Properties ntawm ASTM A501
Cov txheej txheem xeem thiab cov ntsiab lus yog ua raws li cov cai ntawm ASTM A370.
astm a501_Tensile Requirements
Phab ntsa thicknesses Tsawg dua los yog sib npaug rau 6.3mm [0.25in] tsis tas yuav muaj kev cuam tshuam.
Dimensional kam rau ua ntawm ASTM A501
astm a501-Dimensional tolerances
Galvanizing
Rau cov txheej txheem cov raj kom kub -dip galvanized, cov txheej txheem no yuav tsum ua raws li qhov yuav tsum tau ua ntawm Specification A53/A53M.
Ntsuas tus nqi ntawm cov txheej txheej ntawm cov yeeb nkab sab nraud kom txiav txim siab qhov hnyav / thickness.
Qhov tshwm sim
Cov tub ntxhais cov qauv yuav tsum tsis muaj qhov tsis xws luag thiab muaj lub ntsej muag du thaum lub sijhawm ua khoom kub dov.
Deg defects yuav tsum tau muab cais raws li xws li thaum qhov tob ntawm qhov defects tshaj 10% ntawm nominal phab ntsa thickness.
Cov teeb meem uas yuav tsum tau kho yuav tsum raug tshem tawm tag nrho los ntawm kev txiav los yog sib tsoo ua ntej vuam.
Kos npe
Cov cim ASTM A501 yuav tsum muaj cov ntaub ntawv hauv qab no raws li qhov tsawg kawg nkaus:
Tus neeg tsim khoom lub npe
Hom lossis cov cim lag luam
Loj
Lub npe ntawm tus qauv (tsis tas yuav tsum luam tawm xyoo)
Qib
Txhua qhov ntev ntawm cov qauv tubing yuav tsum raug cim los ntawm txoj kev tsim nyog, xws li dov, stamping, stamping, lossis pleev xim.
Rau cov raj xa dej<50 mm [2 in] OD, it is permissible to mark the steel information on a label attached to each bundle.
