Nyob hauv lub ntiaj teb kev lag luam kev lag luam, specifications yog txhua yam. Ntawm cov feem ntau tsis tau nquag tsis to taub cov ntsiab lus yog "teem sijhawm 40" lossis "sch 40." Thaum feem ntau cuam tshuam nrog dub carbon steel yeeb nkab, teem sijhawm 40 yog ib theem tseem ceeb rau cov qib stabless stability thiab siab} tuav lub peev xwm. Tab sis nws txhais li cas tiag?
Kab lus no yuav Demystify SCH 40 stainless hlau yeeb nkab, tshawb nrhiav nws qhov ntev, cov khoom, kev siv, thiab nws muab piv rau lwm lub sijhawm. Txawm hais tias koj yog ib qhov project engineer, muaj txiaj ntsig tshwj xeeb, lossis tsuas yog ua kom paub meej cov qauv kev lag luam, cov lus qhia no muab txoj kev nyuaj siab, kev ua haujlwm.
Dab tsi yog cov teev cov nplaim tawg?
Lo lus "Sij Hawm" (feem ntau cov npe sau ua Sch) yog cov qauv txheej txheem ntawm cov neeg siv khoom siv cov tshuab ua kom zoo nkauj (ASME) los txhais phab ntsa tuab ntawm cov yeeb nkab. Qhov tseem ceeb, nws yog qhov tsis - tus lej lej. Nws uatsisXa mus rau cov yeeb nkab cov khoom, tab sis theej rau nws lub siab -}} khaws cia lub zog.
Tus lej teem sijhawm yog xam siv cov qauv:
Teem Sij Hawm=1000 × × p / s
Qhov twg:
Pyog qhov kev pab cuam siab (PSI)
Syog cov kev ntxhov siab uas tau tso cai ntawm cov khoom (PSI)
Qhov no txhais tau tias rau cov khoom muab (nrog tus nqi ruaj khov-, tus lej lej siab dua qhia tau ib lub phab ntsa tuab dua, uas tuaj yeem tswj hwm cov kev ntsuas sab hauv. Cov caij nyoog sib xws nrog SCH 5, 10, 40, 80, 120, thiab 160.
Cov Sij Hawm Ntawm Teem Sij Hawm 40 Yeeb Nkab
Thaum teem sij hawm 40 yeeb nkab tuaj yeem tsim los ntawm cov hlau hlau (A53, A106) thiab ntau yam alloys, los ntawm kev xav ntawm cov hlau steel, cov qhab nia feem ntau yog:
ASTM A312 Tp304 / 304L:Qhov feem ntau dav siv Antertenitic qib. Nws muaj zoo heev corrosion, muaj peev xwm, thiab weldability. Tus "L" muaj cov ntsiab lus muaj cov pa roj carbon qis rau kev txhim kho weld cheeb tsam kev ncaj ncees.
ASTM A312 TP316 / 316L:Enhanced corrosion kuj, tshwj xeeb tawm tsam chlorides thiab acids, vim qhov sib ntxiv ntawm molybdenum. Qhov no ua rau nws zoo rau cov tub rog, tshuaj lom neeg, thiab ntaub ntawv thov tshuaj.
ASTM A312 Tp321:Degilized nrog titanium, uas txo qhov kev pheej hmoo ntawm chromium carbide nag lossis daus thaum lub sij hawm high {}} kev pab kub.
Pib 40 Cov Yeeb Nkab Yeeb Nkab
Ib qho ntsiab lus tseem ceeb ntawm kev tsis meej pem yog tias lub taub sab nraud (OD) ntawm cov yeeb nkab tau tsau los ntawm nws cov nominal cov yeeb nkab loj (nps). Lub sijhawm txiav txim cov phab ntsa tuab, uas nyeg txhais cov taub sab hauv (ID).
Piv txwv li, NPS 2-nti yeeb nkab ib txwm muaj OD ntawm 2.375 nti, tsis hais cov khoom.
Teem sijhawm 5sNps 2 tus yeeb muaj ib phab ntsa tuab ntawm 0.065 nti thiab ib daim ID ntawm ~ 2.245 nti.
Teem sijhawm 40Nps 2 tus yeeb nkab muaj lub phab ntsa tuab ntawm 0.154 nti thiab ib daim ID ntawm ~ 2.067 ntiv tes.
Sijhawm 80Nps 2 tus yeeb muaj lub phab ntsa tuab ntawm 0.218 nti thiab ib tus lej ID ntawm ~ 1.939 ntiv tes.
Qhov no qhia txog li cas cov yeeb nkab sab hauv thaj chaw nyob hauv sab hauv
Qhov hnyav ntawm lub sij hawm 40 yeeb nkab
Qhov nce phab ntsa thickness ntawm sch 40 yeeb nkab ncaj qha cuam tshuam nws qhov hnyav ib txhais ko taw, uas yog qhov tseem ceeb rau cov qauv kev txhawb nqa thiab kev suav nqi. Stainless hlau (nrog lub ntom ntom ntawm ~ 0.29 lb / nyob rau hauv) yog hnyav dua carbon hlau. Hauv qab no yog cov qauv coj ntawm lub rooj hnyav rau 304/316 sch 40 yeeb nkab.

Qhov kev sib xyaw tshwj xeeb ntawm cov ntsiab yog dab tsi muab hom 316 nws cov pitting zoo tshaj thiab muaj zog.
Qhov sib txawv ntawm cov sijhawm 40 thiab sijhawm 80 yeeb nkab
Qhov no yog kev sib piv tseem ceeb hauv kev tsim cov qauv siv. Lub Koom Haum Me Nyuam YausPhab Ntsa Thickness.
Phab Ntsa Thickness & Siab Ntsuam Xyuas:Lub sij hawm 80 yeeb nkab muaj cov phab ntsa tuab dua li teem sijhawm 40 ntawm tib NPS. Qhov no ua rau nws muaj zog dua, nrog kev ntsuas siab dua (feem ntau yuav luag ob npaug). Piv txwv li, 2 "sch {{40 316 l Cov yeeb nkab kuj yuav muaj lub siab ua haujlwm ntawm ~ 1,500 psi, thaum lub sch 80 yuav siv ~ 2,500 psi.
Qhov hnyav thiab tus nqi:Cov tuab tuab tuab ntawm Daws 80 ua rau nws hnyav dua thiab kim dua vim muaj cov khoom siv rawe nce ntxiv.
Intern Ciam & Ntws:Lub phab ntsa tuab ntawm sch 80 ua rau muaj lub cheeb tsam sib txawv me me, uas nce cov kua dej loj dua thiab lub zog poob hla cov yeeb nkab khiav piv rau Sch 40.
Daim Ntawv Thov: Sch 40Puas yog tus qauv rau nruab nrab -} qhov kev siv hluav taws xob, xws li cov txheej txheem txheej txheem dav dav, kev tiv thaiv kev haus dej, thiab kev tiv thaiv kev siv tshuab, thiab kev tiv thaiv kev siv tshuab, thiab kev tiv thaiv kev siv tshuab, thiab kev tiv thaiv kev siv tshuab, thiab kev tiv thaiv kev siv tshuab, thiab kev tiv thaiv kev siv tshuab, thiab kev tiv thaiv kev siv tshuab, thiab kev tiv thaiv txhua yam.Sch 80yog teev rau high - cov tshuab siab, muaj kev puas tsuaj loj, los yog ua lub zog ua kom muaj zog.
Kev lag luam uas siv Sch 40 yeeb nkab steel
Teem sijhawm 40 stainless hlau yeeb nkab yog ib tug workorse hla kev lag luam hauv kev ua kom haum, kev tu cev, thiab siab nruab nrab siab yuav tsum muaj.
Khoom Noj Thiab Dej Haus:Rau cov kab hloov tsheb huv, thiab ua cov khoom siv ua kom huv si uas huv thiab kev tawm tsam kom tu cov tshuaj ntxuav kom huv.
Kws Tshuaj Thiab Biotech:Siv hauv cov dej huv (PW) thiab dej rau kev txhaj tshuaj (WFI), nrog rau cov txheej txheem kab uas tsis huv thiab huv yog tsis yog {sib ceg.
Tshuaj lom neeg:Ua haujlwm ntau yam ntawm cov tshuaj corrosive, acids, thiab cov kuab tshuaj ntawm nruab nrab kev ntsuas thiab kub.
Dej thiab Wastrater kev kho mob:Siv hauv cov tshuab tuav dej chlorinated dej, tshuaj lom neeg, thiab corrosive corrosive effluent.
Cov kws kos duab thiab tsim kho:Nrov rau tes tuav, cov qauv kev coj ua, thiab cov ntawv thov dai kom zoo nkauj vim nws lub zog thiab kev pom zoo.
Tubrog nkoj thiab ntug hiav txwv:Ua kom tsis txhob muaj Salosion rau cov nkoj thiab cov platform ntug dej rau ballast, bilge, thiab kab nqi hluav taws xob.
Cov ntawv thov ntawm Sch 40 Cov Yeeb Nkab
Tsis pub dhau cov kev lag luam no, cov ntawv thov tshwj xeeb suav nrog:
Cov txheej txheem thiab hloov cov kab rau tsis - kua dej abrasive
Cov khoom siv hluav taws xob rau cov cua compressed, dej, thiab chav dej (qis dua siab)
Ntsuas thiab Sensor Piping

Teem Yug 40 Tus Khaub Ncaws Hlau Cov Nqi
Tus nqi ntawm Sch 40 Stainless hlau yeeb nkab hlau tsis tas tsau thiab yog cuam tshuam los ntawm ntau yam khoom siv hluav taws xob:
Cov khoom siv Raw:Tus neeg tsav tsheb qub yog tus nqi ntawm npib tsib xee, chromium, thiab molybdenum ntawm lub ntiaj teb cov hlau hom. Tus nqi tuaj yeem hloov kho.
Stainless Hlau Qib:TPPP3 / 304L feem ntau yog kev lag luam tshaj plaws. TPP316 / 316L txib tus nqi siab dua vim nws cov ntsiab lus molybdenum. Qib Tshwj Xeeb zoo li 317L lossis 904L yog kim dua.
Loj thiab kom muaj nuj nqis:Diamool diameters raug nqi ntau dua rau ib txhais ko taw. Cov ntawv loj dua feem ntau tau txais tus nqi qis dua.
Kev Xav Tau Lag Luam:Ntiaj teb muaj kev thov kev cuam tshuam cuam tshuam cov nqi ib zaug.
Chaw tsim tshuaj paus thiab keeb kwm:Cov nqi tuaj yeem sib txawv ntawm cov mills domestic thiab cov neeg thoob ntiaj teb.
Raws li ntawm [Lus Cim: Koj yuav hloov qhov no nrog ib lub sijhawm dav dav, piv txwv li, "Mid-2024"], nqi rau sch {}} / 304L yeeb nkab tuaj yeem los ntawm$ 5 txog $ 50 rau ib txhais taw, nyob ntawm tes ntau ntawm txoj kab uas hla. Nws yog qhov tseem ceeb kom tau txais cov lus qhia tam sim no los ntawm koj cov kev pabcuam steel hlau raws li koj qhov project qhov kev xav tau tshwj xeeb.
Tag
Teem sijhawm 40 yog deb tshaj tsuas yog tus lej. Rau cov hlau stainless, nws sawv cev rau ntau yam thiab cov neeg siv hluav taws xob khov kho kom zoo, ntws peev xwm, muaj zog, thiab tus nqi- ua hauj lwm zoo. Nkag siab txog nws qhov ntev, cov khoom, thiab nws muab piv rau lwm cov neeg siv cov khoom siv tau yog rau cov ntawv thov kom raug rau txhua qhov kev lees paub, kev ua haujlwm, thiab ua haujlwm tau zoo rau xyoo los. Thaum tsis paub tseeb, ib txwm nyob sab laj cov qauv kev cai lij choj thiab ua haujlwm nrog tus kws tshaj lij los ua koj cov khoom xaiv.
