ASTM A500 CARBON STEEL MECHANICAL PROPERTIES
Tus nqi ntawm stretching nro uas cov khoom muaj peev xwm tiv tau ua ntej tawg los yog ua tsis tiav yog hu ua nws lub zog tensile. Lub zog tensile kawg ntawm A500 carbon steel yog xam los ntawm kev faib nws thaj chaw los ntawm kev ntxhov siab siv rau nws, uas yog sawv cev hauv phaus lossis tons ib square inch ntawm cov khoom. Lub zog tensile yog ib qho tseem ceeb qhia txog ASTM A500 lub peev xwm los ua hauv ib daim ntawv thov. Lub zog tensile ntawm A500 carbon steel yog qhia hauv daim duab hauv qab no.

ASTM A500 CARBON STEEL PERMISSIBLE DIMENSIONAL VARIATIONS rau sab nraud DIMENSIONS
Kev ntsuas sab nraud rau ASTM A500 carbon steel tube yuav tsum tau noj tsawg kawg 2 "(50.8mm) los ntawm txhua qhov kawg.
Sab nraud txoj kab uas hla ntawm puag ncig structural tubing muaj ib tug nominal OD ntawm 1.900 "(48.26mm) los yog tsawg dua yuav txawv tsis ntau tshaj 0.5 feem pua ntawm qhov luaj li cas, sib npaug mus rau ze tshaj 0.005 "(0.13mm). Sab nraud txoj kab uas hla yuav tsis txawv ntau tshaj 0.75 feem pua, sib npaug rau qhov ze tshaj 0.005 ", rau nominal ODs ntawm 2" (50.8mm) thiab ntau dua.
Square thiab rectangular structural raj yuav tsum tau ntsuas nyob rau hauv lub flats nrog ib tug pub rau convexity los yog concavity. Qhov loj me uas tau teev tseg yuav tsum tsis pub tshaj qhov ntxiv / rho tawm qhov kam rau ua tau teev nyob rau hauv cov lus hauv qab no.
ASTM A500 SQUARE & RECTANGULAR STEEL TUBING
Muaj ntau qhov kev txiav txim siab uas yuav tsum tau suav rau thaum txiav txim siab rau sab nraud qhov ntev ntev rau cov square thiab square steel tubing. Daim ntawv qhia hauv qab no thiab cov cwj pwm hauv qab no piav qhia qhov tseeb sab nraud qhov kam rau ua rau A500 carbon steel.

YUAV TSUM TAU TXAIS PHEM
Qhov tsawg kawg nkaus phab ntsa thickness ntawm txhua qhov kev ntsuas yuav tsum tsis pub tsawg tshaj 90% ntawm cov phab ntsa nominal thickness. Qhov siab tshaj plaws phab ntsa thickness, tsis suav nrog weld seams, yuav tsum tsis txhob ntau tshaj 110% ntawm cov nominal phab ntsa thickness. Phab ntsa thickness ntawm square structural tubing thiab rectangular structural tubing yuav tsum tau ntsuas nyob rau hauv nruab nrab ntawm lub tiaj tus.
STRAIGHTNESS YUAV TSUM
Rau cov qauv raj, qhov tso cai hloov pauv hauv qhov ncaj yog 1/8 "xij rau tag nrho qhov ntev ntawm taw (lossis 10.4mm npaug ntawm cov meters) muab faib los ntawm tsib.
SIB SQUARENESS REQUIREMENT
Rau square structural tubing thiab rectangular structural tubing, sab nyob ib sab yuav deviate ntawm 90℃los ntawm tsis ntau tshaj ± 2 degree.
Daim ntawv thov ntawm ASTM A500 STEEL STRUCTURAL PIPE
Nyob ntawm nws qhov loj me, A500 cov yeeb nkab yog siv rau hauv kev tsim kho, cov khoom siv hnyav, kev ua liaj ua teb, tshuab, fabrication, thiab cov hom phiaj dav dav. Hauv kev tsim kho, lawv feem ntau siv los ua cov kab hluav taws xob lossis kab. Hauv kev tsim cov cuab yeej siv hnyav, lawv tau siv hauv kev tsim cov tshuab xws li tsheb laij teb thiab excavators. Hauv kev ua liaj ua teb, lawv feem ntau siv rau hauv kev tsim kho cov kav dej. Hauv kev tsim khoom, lawv feem ntau siv los tsim cov ntu rau cov kab hlau thiab cov ncej. Raws li qhov tshwm sim, ASTM A500 cov kav dej muaj ntau yam kev siv hauv ntau qhov kev lag luam. ASTM A500 tubing tuaj nyob rau hauv plaub qib: Qib A, Qib B, Qib C, thiab Qib D. Txhua qib muaj cov kev cai tshwj xeeb thiab cov khoom siv sib txawv uas yuav tsum tau ua kom tau raws li ASTM A500-ua raws.
