ASTM A105Yog tus qauv tsim los ntawm Asmeskas haiv neeg rau kev sim thiab cov ntaub ntawv (xws li siv cov roj ntshaASTM A105 Threaded CouplingsNyob rau hauv high - kub thiab siab {{{{{1} pa cov txheej txheem los ntawm cov khoom siv raw ua tiav cov khoom lag luam. Nrog nws cov dav dav thiab lub hom phiaj xav tau, nws muab kev nyab xeeb ntawm kev ua haujlwm ntawm cov raj xa hluav taws xob.
ASTM A105 Khoom Siv Khoom Siv
ASTM A105 cov khoom siv ua pov thawj zoo ua tau zoo. Nyob rau hauv cov nqe lus ntawm cov neeg kho tshuab:
Lub zog tensileNtau dua los yog sib npaug rau 485 mpa
Paib lub zogNtau dua los yog sib npaug rau 250 MPa
ElongationNtau dua los yog sib npaug rau 20%
Nws ua kom pom kev zoo thiab lub tensile tsis kam, ua tau zoo nrog kev cuam tshuam ntawm lub siab thiab sab nraud kev ua haujlwm thaum lub sijhawm ua haujlwm sab nraud.
Hauv corrosion tsis kam, cov khoom ua tau zoo nyob rau hauvambient thiab moderate -} Qhov chaw ib puag ncigTawm tsam cov kev daws teeb meem neutral muaj kua txob, chav, thiab lwm yam xov xwm, txo qhov kev pheej hmoo ntawm kev ua kom haum rau xeb kev puas tsuaj thiab lub neej pabcuam kev ua haujlwm txuas ntxiv. Ib qho ntxiv, nws muaj cov lus qhia zoo dua **
