Tshawb nrhiav qhov tseem ceeb ntawm SCH 40 hauv kev tsim kho hlau
Cov yeeb nkab Schedule 40 feem ntau lees txais tias yog ib qho siv ntau zaus thiab hloov tau yooj yim heevdaim ntawv ntawmcov yeeb nkab hlaunyob rau hauv lub sector hlau.Txawm li cas los xij, ib lo lus nug tshwm sim ntawm cov engineers, cov neeg yuav khoom, thiab cov neeg ua vaj tse: Puas yog Schedule 40 yeeb nkab haum rau cov hom phiaj kev tsim kho?
Tsab xov xwm no yuav tshawb nrhiav txog kev siv Daim Ntawv Teev Npe 40 thiab xav txog nws qhov tseem ceeb hauv cov ntsiab lus ntawm cov qauv.
Nkag siab txog qhov yog "Teem Caij 40"
Lub npe Schedule 40 tsis qhia txog qib khoom siv lossis lub zog tshwj xeeb - nws hais txog phab ntsa tuab ntawm cov yeeb nkab uas ua raws liASME/ASTMcov lus qhia txog qhov ntev.
Los ntawm lub rooj peb tuaj yeem pom, cov yeeb nkab 2-nti Schedule 40 muaj phab ntsa tuab ntawm 3.91 hli, thaum cov yeeb nkab 8-nti ntsuas 8.18 hli. Cov qhov ntev no tau raug qauv los ntawm ASME B36.10M, feem ntau yog rau cov kav dej siab hauv cov kab ke xa dej.
Tsim los rau Kev Nyuaj Siab, Tsis Yog Cov Khoom Siv Hauv Tsev
Cov kav dej Schedule 40 feem ntau yog tsim tawm raws li cov qauv zoo li ASTM A53, ASTM A106, lossisAPI 5LCov lus qhia no hais txog kev tswj lub siab, kev vuam tau, thiab kev tiv taus xeb, es tsis yog lub peev xwm ntawm cov qauv.
Qhov no txhais tau hais tias cov kav dej tau tsim los kom tiv taus lub zog sab hauv, tsis tas yuav yog lub zog sab nraud xws li khoov lossis nias hauv cov qauv tsim.
Puas Siv Tau Rau Kev Tsim Kho Vaj Tse?
Yog—txawm hais tias muaj qee qhov kev txwv.
Cov yeeb nkab Schedule 40 siv tau rau hauv cov haujlwm tsim kho uas tsis hnyav lossis tsis tseem ceeb, tshwj xeeb tshaj yog hauv cov ntawv thov xws li:
- Cov laj kab, cov laj kab, thiab cov laj kab tes
- Cov thav duab txhawb nqa thiab cov txee dai khaub ncaws
- Cov ntawv qhia thiab cov rooj sib txoos me me
Hauv cov xwm txheej no, Daim Ntawv Teev Npe 40 yog qhov kev xaiv pheej yig vim nws lub zog txaus rau cov ntawv thov tsis tseem ceeb thiab nws muaj ntau yam.
Txawm li cas los xij, thaum peb xaiv cov khoom rau cov qauv uas muaj peev xwm nqa tau lossis cov khoom sib xyaw hauv cov qauv tsim kho vaj tse uas tau ntawv pov thawj thiab cov qauv tsim, cov yeeb nkab hlau qib xws li ASTM A500 lossis ASTM A252 yuav tsum tau xaiv hloov. Vim tias cov no tau tsim tshwj xeeb rau kev ruaj khov ntawm cov qauv thiab dhau los ntawm kev sim kev ua haujlwm ntawm cov khoom siv.
Kev Sib Piv ntawm Cov Tubing Txheej Txheem 40 thiab ASTM A500
Raws li lub rooj qhia, thaum muaj kev xav tau lub zogh, kev kam rau siab sib xws, thiab kev ua tau zoo tas li hauv qab kev thauj khoom, qhov kev xaiv zoo dua yog ASTM A500.
Cov Kev Xav Kawg
Cov yeeb nkab txuas ntxiv mus rau Schedule 40yuav yog ib hom yeeb nkab hlau uas siv dav tshaj plaws thiab pheej yig tshaj plaws. Nws ua tau zoo heev rau cov txheej txheem kua dej, kev tsim khoom dav dav, thiab cov haujlwm tsim kho me me.
Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum xaiv cov yeeb nkab hlau lossis cov raj uas tau ntawv pov thawj (xws li ASTM A500 lossis A252) rau cov haujlwm uas xav tau kev ntseeg siab ntawm cov qauv tsim.
Qhov no ua kom tsis yog tsuas yog ua raws li cov cai tsim qauv xwb, tab sis kuj tseem muaj kev nyab xeeb thiab kev ua tau zoo mus sij hawm ntev ntawm koj qhov project.
