Xov luj tshib-- ntau yam forged haum
Mar 03, 2023
Lub luj tshib threaded yog ib hom kav dej siv los hloov cov kev taw qhia ntawm lub raj xa dej los ntawm 90 degrees. Nws yog hu ua "threaded" luj tshib vim nws muaj xov ntawm ob qho kawg uas tso cai rau nws txuas nrog lwm cov xov fittings lossis cov kav dej.
ASME B16.11 Threaded luj tshib feem ntau yog ua los ntawm hlau, xws li tooj dag lossis stainless hlau, tab sis kuj tuaj yeem ua los ntawm cov yas lossis lwm yam khoom siv. Lawv tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab xov hom kom haum raws li cov yeeb nkab sib txawv thiab kev siv.
Txhawm rau txhim kho lub luj tshib, ob lub kav dej yuav tsum tau koom ua ntej threaded rau txhua qhov kawg ntawm lub luj tshib. Cov yeeb nkab ciaj ntswj los yog lwm yam khoom siv tsim nyog yog siv los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws, nws raug nquahu kom siv cov khoom sib xyaw ua ke ntawm cov khoom sib xyaw ua ke.
ASME B16.11 Threaded luj tshib feem ntau yog siv hauv cov kav dej hauv tsev thiab kev lag luam, nrog rau kev siv hauv kev lag luam xws li roj thiab cov kav dej. Lawv muaj ntau yam, yooj yim rau nruab, thiab tuaj yeem siv los hloov cov kev taw qhia ntawm cov kav dej hauv qhov chaw nruj uas lub luj tshib yuav tsis haum.
Muaj ntau qhov zoo ntawm kev siv ANSI B16.11 threaded luj tshib hauv cov kav dej thiab cov kav dej:
Kev Txhim Kho Yooj Yim: ANSI B16.11 Threaded luj tshib yog ib qho yooj yim rau nruab vim lawv tsis tas yuav muaj vuam lossis cov cuab yeej tshwj xeeb. Cov threaded kawg ntawm lub luj tshib tsuas yog ntsia hlau mus rau threaded kawg ntawm cov kav dej, ua rau nws yooj yim thiab ceev txheej txheem.
Ntau yam: 90 degree Threaded luj tshib tuaj yeem siv ntau yam kev siv raws li lawv muaj nyob rau hauv ntau qhov sib txawv thiab hom xov. Lawv tuaj yeem siv los txuas cov kav dej ntawm qhov sib txawv, cov khoom siv, thiab xov hom.
Adjustable: 90 degree Threaded luj tshib tuaj yeem hloov kho rau lub kaum sab xis lossis kev taw qhia, ua rau lawv zoo tagnrho rau kev teeb tsa hauv qhov chaw nruj uas lub luj tshib yuav tsis haum.
Leak-Free: 45 degree Threaded kev sib txuas feem ntau muaj kev nyab xeeb dua thiab tsis muaj paug piv rau lwm hom kev sib txuas xws li thawb-haum lossis compression fittings. Qhov no yog vim hais tias cov xov tsim ib lub foob kaw ntom nti uas tiv thaiv cov xau thiab ua kom muaj kev sib txuas ruaj ntseg.
Durable: 45 degree Threaded luj tshib feem ntau yog ua los ntawm cov ntaub ntawv zoo xws li tooj dag lossis stainless hlau, ua rau lawv ruaj khov thiab kav ntev. Lawv tuaj yeem tiv taus siab thiab kub, ua rau lawv tsim nyog rau kev siv hauv kev lag luam.
Threaded luj tshib muaj nyob rau hauv ntau qhov ntau thiab tsawg kom haum rau cov yeeb nkab sib txawv. Qee qhov loj tshaj plaws ntawm threaded luj tshib muaj xws li:
1/2 nti threaded luj tshib
3/4 nti threaded luj tshib
1 nti threaded luj tshib
1/4 nti threaded luj tshib
1/2 nti threaded luj tshib
2 nti threaded luj tshib
Txawm li cas los xij, carbon steel threaded luj tshib kuj tuaj yeem pom nyob rau hauv qhov me me lossis loj dua nyob ntawm seb cov ntawv thov tshwj xeeb thiab cov yeeb nkab loj yuav tsum tau ua. Nws yog ib qho tseem ceeb los xyuas kom meej tias lub luj tshib loj sib npaug ntawm qhov loj ntawm cov yeeb nkab uas nws txuas nrog txhawm rau txhawm rau xyuas kom muaj kev ruaj ntseg thiab tsis muaj kev sib txuas.
Alloy threaded luj tshib yog siv nyob rau hauv ntau yam kev siv nyob rau hauv cov kav dej thiab kav dej, nrog rau hauv kev lag luam chaw. Qee qhov kev siv ntawm threaded luj tshib muaj xws li:
Hloov cov yeeb nkab taw qhia: Duplex threaded luj tshib feem ntau yog siv los hloov cov kev taw qhia ntawm cov yeeb nkab los ntawm 90 degrees. Qhov no yog qhov muaj txiaj ntsig zoo nyob rau hauv cov xwm txheej uas cov kav dej yuav tsum tau taug kev ncig cov teeb meem lossis kom haum rau hauv qhov chaw nruj.
Txuas Cov Yeeb Nkab: Nickel Alloy threaded lub luj tshib tuaj yeem siv los txuas ob lub kav dej ua ke. Lawv feem ntau siv rau hauv cov kav dej los txuas cov khoom siv xws li cov dab dej, chav dej, thiab da dej rau cov dej loj.
Gas thiab Roj Pipelines: Threaded luj tshib feem ntau yog siv rau hauv cov pa roj thiab cov kav dej los hloov cov kev taw qhia ntawm cov kav dej los yog txuas cov seem sib txawv ntawm cov yeeb nkab ua ke.
HVAC Systems: Threaded luj tshib yog siv rau hauv cov cua sov, qhov cua, thiab cua txias (HVAC) systems los txuas ductwork ua ke thiab hloov cov kev taw qhia ntawm huab cua ntws.
Cov ntawv thov kev lag luam: Cov xov lub luj tshib yog siv ntau yam kev siv hauv kev lag luam, xws li hauv cov chaw ua tshuaj, qhov chaw uas lawv tau siv los txuas cov ntu sib txawv ntawm cov kav dej ua ke los yog hloov cov kev taw qhia ntws.
