Dab tsi yog qee yam ntawm cov khoom siv feem ntau cov yeeb nkab-fitter siv thaum vuam?Butt welded fittings, tau kawg.Tab sis koj puas tau xav tias yog vim li cas nws feem ntau yog yooj yim mus nrhiav fittings uas ua hauj lwm?
Thaum nws los txog rau lub Hoobkas tsim pob tw vuam fittings, muaj cov qauv tshwj xeeb uas yuav tsum tau ua kom tau raws li lub sijhawm tsim khoom.Qhov nrov tshaj plaws yog ANSI thiab ASME.Cia peb saib ntawm ASME B 16.9 tus qauv thiab nws txawv li cas ntawm ANSI tus qauv.
ASME B 16.9:Factory-MadeWrought Butt Vuam Fittings
ASME B 16.9 yog tsim los ntawm American Society of Mechanical Engineers.B 16.9 yog hais txog lub Hoobkas tsim pob tw vuam fittings.ASME B 16.9 tswj hwm qhov muaj peev xwm, qhov ntsuas siab, qhov loj me, kos npe, cov khoom siv, haum qhov ntev, qhov sib txawv ntawm qhov chaw, kev npaj kawg, kev tsim cov ntawv pov thawj, kev sim ntau lawm, thiab kev ua siab ntev.Qhov kev tsim qauv no ua kom ntseeg tau tias cov fittings raug tsim raws li lawv yuav tsum tau ua kom muaj peev xwm thiab cov kev qhia tshwj xeeb, ua kom yooj yim rau kev sib xyaw tshiab rau cov khoom uas twb muaj lawm, thiab ua kom muaj kev nyab xeeb, lub zog, thiab ruaj khov.
Butt welding tuaj yeem yog cov txheej txheem automated lossis los ntawm tes, siv los txuas cov hlau ua ke.Wrought taub qab vuam fittings feem ntau haum yooj yim;lawv tau tsim kom lawv tuaj yeem welded ncaj qha mus rau lwm qhov haum.Nrog rau qhov ntawd hauv siab, txawm li cas los xij, lawv yuav tsum tau tsim los rau qee cov qauv, yog li lawv tuaj yeem haum rau lwm cov fittings.Hom pob tw weld haum tuaj yeem suav nrogluj tshib, kaus mom, tees, reducers, thiab outlets.
Vim hais tias buttwelding yog ib qho ntawm cov txheej txheem vuam ntau tshaj plaws thiab kev sib koom ua ke, cov kws tsim khoom siv tshuab zoo li yuav siv thiab ua haujlwm nrog lub Hoobkas tsim wrought buttweld fittings ncaj nraim.Cov neeg tsim khoom ntawm pob tw weld fittings yuav tsum txhawj xeeb lawv tus kheej nrog cov qauv thiab cov lus qhia tshwj xeeb.
ANSI vs ASME Standards
Cov qauv ANSI vs ASME rau qee qhov chaw tsim khoom tuaj yeem sib txawv.Yog li, cov engineers yuav xav paub seb lawv puas ua haujlwm rau ANSI lossis ASME cov qauv, vim tias ASME cov qauv feem ntau tshwj xeeb thiab cov qauv ANSI yuav muaj ntau dua.ASME yog tus qauv uas tau txiav txim siab pipefitting txij thaum xyoo 1920s.Rau feem ntau cov ntawv thov, ua raws li ASME cov qauv yuav ua raws li cov qauv ANSI.
ANSI yog tsim los ntawm American National Standards Institute.ANSI tswj hwm ntau yam kev lag luam, thaum ASME tshwj xeeb tsim rau boilers, cov hlab ntsha siab, thiab lwm qhov chaw zoo sib xws.Yog li, thaum qee yam yuav ua tau raws li ANSI cov qauv, nws yuav tsis ua raws li ASME cov qauv;ASME cov qauv yuav yog qhov tshwj xeeb lossis nruj dua.Thaum nws los txog rau tus qauv B16.9, txawm li cas los xij, ANSI thiab ASME cov qauv yuav zoo sib xws.
Cov qauv thiab cov kev cai yeej ib txwm tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv ib yam dab tsi raws li high-pressure li pipefittings thiab boilers.Vim tias cov qauv kuj tseem hloov tau, nws yog ib qho tseem ceeb rau cov koom haum los muab qee lub sijhawm los hloov kho lawv tus kheej ntawm kev hloov pauv thiab ntxiv.Ntawm Steel Forgings, peb ib txwm ua haujlwm los xyuas kom meej tias peb cov khoom ua tau raws li cov qauv xav tau - thiab lawv mus rau saum toj thiab dhau ntawm qhov zoo thiab sib xws.
