FAQ:
Q1: Dab tsi yog ASTM A325 tag nrho threaded stud bolt?
ASTM A325 yog tus qauv tshwj xeeb rau siab -lub zog hnyav hex qauv bolts. Thaum tus txheej txheem ib txwm tsom mus rau lub taub hau bolts, "tag nrho threaded stud bolts" xa mus rau cov xov txuas txuas ntxiv tsim los ua kom tau raws li cov khoom siv thiab tshuaj lom neeg ntawm A325 (tam sim no feem ntau hloov los ntawm ASTM F3125 Qib A325).
Q2: Lub zog tensile ntawm A325 stud ntsia liaj qhov rooj yog dab tsi?
A325 fasteners muaj qhov tsawg kawg nkaus tensile lub zog ntawm 120 ksi (825 MPa) rau txoj kab uas hla mus txog 1 nti. Rau txoj kab uas hla ntawm 1-1/8 "thiab 1-1/2", qhov tsawg kawg nkaus tensile lub zog tseem yog 120 ksi raws li qhov tshiab F3125 specification.
Q3: A325 vs. A490 Stud Bolts: Kuv yuav xaiv qhov twg?
Xaiv A325 rau cov txheej txheem steel ua haujlwm uas nyiam dua ductility. Xaiv A490 thaum koj xav tau lub zog siab dua (150 ksi yam tsawg kawg nkaus tensile)
Q4: Puas yog ASTM A325 stud bolts tuaj yeem ua tiav threaded?
Standard A325 structural bolts yog feem ntau hnyav hex bolts nrog ib tug tshwj xeeb shank ntev. Txawm li cas los xij, rau cov ntawv thov uas xav tau kev sib txuas tsis tu ncua lossis kev sib txuas tshwj xeeb flange, tag nrho threaded studs tuaj yeem tsim kom tau raws li A325 tshuaj thiab lub cev.
Q5: Dab tsi yog qhov dav rau A325 fasteners?
Feem ntau yog Kub-Dip Galvanized (HDG) rau ASTM F2329 rau kev tiv thaiv corrosion zoo tshaj hauv qhov chaw sab nraum zoov.
Q6: Kuv puas tuaj yeem txuas ASTM A325 stud bolts?
Tsis yog, vuam tsis pom zoo. A325 yog cov cua sov- kho, nruab nrab- carbon steel. Cov cua kub hnyav ntawm vuam yuav hloov cov cua sov- kho cov khoom, ua rau poob loj hauv tensile lub zog thiab muaj peev xwm brittleness.
Q7: Tus nqi sib txawv ntawm A325 thiab A193 B7 studs yog dab tsi?
A325 studs feem ntau 15-25% kim dua tus qauv A193 B7 studs.
Q8: Cov txiv ntseej thiab cov ntxhua khaub ncaws dab tsi yuav tsum siv nrog A325 studs?
Txhawm rau kom muaj kev sib koom ua ke, siv ASTM A563 Qib DH lossis ASTM A194 Qib 2H hnyav hex ceev. Rau cov ntxhua khaub ncaws, ASTM F436 hardened steel washers yog yuav tsum tau.
