SCHEDULE 40 STEEL PIPE yog dab tsi?

 

Teem caij 40 steel yeeb nkab yog cov kav dej ntau tshaj plaws. Nws tuaj yeem ua tau galvanized - txawm tias nws tsis tas yuav tsum yog - thiab feem ntau yog siv hauv cov dej thiab roj. Nws kuj tseem tuaj yeem tshwm sim hauv qhov chaw uas xav tau kev kho kom zoo nkauj lossis kev txhawb nqa.

Nws ua rau cov yeeb nkab zoo heev vim nws muaj ntau yam thiab kev ua tau zoo. Nrog rau lub sijhawm 40 steel yeeb nkab nyob rau hauv lub siab ntau heev los ua, cia peb tham txog nws yog dab tsi thiab vim li cas nws tuaj yeem yog qhov kev xaiv zoo rau ntau qhov haujlwm.

 

Lub Sijhawm Yeeb Nkab yog dab tsi?

A yeeb nkab teem caij (SCH)yog ib qho kev ntsuas ntawm cov yeeb nkab steel lub nominal phab ntsa thickness.

Yav dhau los, hlau fabricators siv peb cov yeeb nkab qhov ntev - tus qauv, muaj zog ntxiv, thiab ob npaug ntxiv zog. Tsuas yog muaj peb qhov kev tsis txaus ntseeg no tsis muaj txiaj ntsig, txawm li cas los xij. Yog li niaj hnub no, cov kav dej steel tuaj hauv 14 lub sijhawm sib txawv.

Qhov feem ntau siv ib qho yog teem caij 40.

 

Vim li cas nws thiaj hu ua lub sijhawm 40 yeeb nkab?

Cov naj npawb ntawm cov yeeb nkab tsis yog qhov dav. Hauv lwm lo lus, SCH 40 tsis txhais hais tias cov yeeb nkab yog 40 millimeters lossis 40 ntiv tes.

Cov kev txwv rau txhua lub sijhawm yog txiav txim siab los ntawm ASME B36.10M, uas yog tus qauv tswj hwm seamless thiab welded steel yeeb nkab qhov ntev. ASME B36.10M txiav txim cov lej uas xaiv txhua qhov loj.

Qib ntawm Schedule 40 Steel Pipe

Feem ntau lub sijhawm 40 steel yeeb nkab yog tsim los ntawm cov hlau me me. Qhov no txhais tau tias nws muaj cov ntsiab lus carbon ntawm li 0.2% mus rau 0.25%. Qhov ntawd yog heev, tsawg heev, ua cov alloy feem ntau ferrous nyob rau hauv muaj pes tsawg leeg.

Txhawm rau txhim kho SCH 40 steel yeeb nkab qhov kev tiv thaiv corrosion, steel tuam ntxhab feem ntau galvanize cov hlau, uas txhais tau hais tias yuav tsum phaj nws nrog ib txheej ntawm zinc. Yog tias qhov kev xaiv no tsis tsim nyog, teem caij 40 yeeb nkab tuaj hauv stainless hlau.

A53 steel yeeb nkab yog qib feem ntau cuam tshuam nrog SCH 40 steel yeeb nkab, tab sis koj tuaj yeem pom cov sijhawm no hauv lwm qib.

Teem caij 40 Steel Pipe Dimensions

Thicknesses yog ntsuas los ntawm ob phab ntsa thickness thiab sab nraud txoj kab uas hla. Piv txwv li, 1/8-inch nominal loj teem caij 40 yeeb nkab muaj ib txoj kab uas hla sab nraud ntawm 0.405 thiab phab ntsa thickness ntawm 0.068. Nws qhov hnyav ib ko taw sawv ntawm 0.245.

Ib qho yeeb nkab ntau dua yog {{0}}inch teem caij 40 steel yeeb nkab. Cov yeeb nkab no sab nraud txoj kab uas hla yog 4.5 nrog phab ntsa tuab ntawm 0.237 thiab qhov hnyav ib ko taw ntawm 10.79.

 

Qhov loj npaum li cas yog teem caij 40 steel yeeb nkab?

Cov khoom siv steel yeeb nkab no los ntawm ntau qhov ntev. Qhov loj ntawm cov yeeb nkab, nws txoj kab uas hla nominal, qhov tseeb hauv txoj kab uas hla, thiab qhov tseeb sab nraud txoj kab uas hla tag nrho haum nyob rau hauv txoj cai tsis.

Piv txwv li, ib lub sij hawm 40 yeeb nkab uas yog 2.5 nti inch yuav yog 2.469 nyob rau hauv qhov tseeb nyob rau hauv txoj kab uas hla thiab 2.875 nyob rau hauv qhov tseeb sab nraud txoj kab uas hla.

Ntawm Kloeckner, peb tuaj yeem muab lossis txiav cov sijhawm 40 steel kav yuav luag txhua qhov ntev koj xav tau.

Qhov hnyav ntawm Teem caij 40 Hlau Yeeb Nkab

Raws li txoj cai dav dav, qhov hnyav ib ko taw sawv ntawm 1.68 lbs.

Qhov hnyav npaum li cas tuaj yeem teem sijhawm 40 steel yeeb nkab tuav?

Qhov hnyav npaum li cas nws tuaj yeem tuav tau nyob ntawm ntau yam. Yog tias koj yuav cov yeeb nkab txheem - A53- qib, cov hlau dub - nws yuav ua kom pom 30,000 psi tawm lub zog.

Muab cov ntaub ntawv ntawd…

Wb hais tias koj siv ib lub yeeb nkab ib-inch hla ib tug plaub-taw ncua. Qhov nruab nrab yuav tsum tuav 300 lbs nrog ib lub quarter-inch mus tas li deflection. Ntxiv 50 lbs rau lub yeeb nkab ntawd, thiab nws yuav quav rau koj.

Tshuaj muaj pes tsawg leeg ntawm Schedule 40 Steel Pipe

Teem caij 40 yeeb nkab hais txog lub nominal phab ntsa thickness, tsis yog qib. Yog li ntawd, cov tshuaj muaj pes tsawg leeg ntawm cov yeeb nkab lub sij hawm tsis tas yuav tsum sib xws.

Txawm li cas los xij, lub sijhawm 40 yeeb nkab yog tsim los ntawm cov pa roj carbon tsawg, feem ntau yog qib A53 steel yeeb nkab. Nws cov tshuaj muaj pes tsawg leeg kuj txawv ntawm ntau hom thiab welds, tab sis raws li cov ntsiab lus ntawm kev siv, hom S seamless weld A53 steel zoo li no:

Cov pa roj carbon - 0.25% (max)

Manganese - 0.95% (max)

Phosphorous - 0.05% (max)

Sulfur - 0.045% (max)

Tooj - 0.4% (max)

Nickel - 0.4% (max)

Chromium - 0.4% (max)

Molybdenum - 0.15% (max)

Vanadium - 0.08% (max)

Qhov sib txawv ntawm Teem 40 thiab Teem 80 Yeeb Nkab

Teem caij 40 thiab teem caij 80 cov kav dej zoo sib xws. Lawv zoo ib yam, qhov tseeb, uas qee cov neeg sib sau ua ke ob.

Qhov tseeb, txawm li cas los xij, lub sijhawm 40 yeeb nkab muaj cov phab ntsa nyias dua li lub sijhawm 80. Yog li ntawd, lub sijhawm 80 tuaj yeem tswj tau siab dua li lub sijhawm 40, yog li nws feem ntau siv rau kev lag luam.

Yuav ua li cas paub yog tias lub sijhawm 40 yeeb nkab tuaj yeem tswj tau lub siab

Daim ntawv qhia lej tuaj yeem pab koj txiav txim siab seb lub sijhawm 40 lossis lub sijhawm 80 puas yog rau koj qhov project.

SCH=(1,{2}})*(P/S)

Hauv qhov sib npaug no, P sib npaug ntawm cov yeeb nkab lub siab ua haujlwm sab hauv, thiab S sawv rau qhov kev ntxhov siab npaum li cas cov khoom tuaj yeem tiv taus.

Piv txwv li, yog tias koj cov yeeb nkab muaj lub siab ua haujlwm sab hauv ntawm 450 psi thiab tus nqi S ntawm 12, 000, ces koj qhov sib npaug yuav zoo li no:

(1,000) *(450/12,000) = 37.5

37.5 yog ze rau SCH 40 yog li koj yuav tsum muaj kev nyab xeeb xaiv lub sijhawm ntawd.

Kev lag luam uas siv Sch 40 Steel Pipe

Ntau qhov kev lag luam siv SCH 40 steel yeeb nkab, tshwj xeeb tshaj yog cov kev lag luam uas yuav tsum tau muab cua, roj, thiab dej ntawm qhov kub thiab txias. Cov yeeb nkab lub sij hawm no kuj pom ntau siv hauv kev tsim kho kev ua haujlwm qhov twg nws txoj kab uas hla, lub zog, thiab kev ua kom muaj zog ua rau nws xaiv tau.

Daim ntawv thov ntawm Sch 40 Steel Pipe

Cov khw muag khoom kho vajtse feem ntau muag cov sijhawm 40 steel kav. Ntau tus DIYers nyiam siv cov khoom no hauv cov haujlwm muaj tswv yim. Teem caij 40 steel yeeb nkab ua kom ruaj khov thiab txaus nyiam cov ntaub thaiv kab hlau rhuav, txee, lub tsho tiv no, teeb hauv pem teb, thiab cov ntawv xov xwm racks.

Tau kawg, teem caij 40 yeeb nkab daim ntawv thov tseem ceeb yog thauj cov dej kub, siab-siab rau kev lag luam thiab thaj chaw nyob hauv kev lag luam roj thiab roj.

Teem caij 40 Steel Pipe Nqe

Teem caij 40 steel yeeb nkab nqi sib txawv heev thiab nyob ntawm seb yam xws li ntev, qib, thiab ntim ntawm kev yuav khoom. Yog tias koj yuav cov yeeb nkab siab siab ncaj qha los ntawm lub tuam txhab uas muaj cov kev pabcuam zoo, xws li GNEE steel .

Yog xav paub ntxiv txog lwm yam steel yeeb nkab, steel tube, thiab steel phaj khoom, mus saib los ntawm peb lub tsev qiv ntawv ntawm cov khoom los yog tiv tauj peb ncaj qha.
