To kev nkag siab cov xaim lub sijhawm
Cov khoom siv yeeb nkab ntim yog cov txheej txheem sib txawv ntawm kev ntsuas cov phab ntsa tuab ntawm cov kav hlau. Qhov siab dua tus lej teem sijhawm, cov tuab tuab dua cov yeeb nkab phab ntsa, uas cuam tshuam ncaj qha rau nws lub zog, siab muaj peev xwm, thiab qhov hnyav. Teem sijhawm 20 thiab sijhawm 40 yog ob qho kev tsim qauv hauv kev lag luam thiab cov lag luam piping. Thaum lawv yuav muaj tib lub nominal hla, lawv cov phab ntsa tuab sib txawv, ua rau muaj cov yam ntxwv sib txawv thiab kev siv. Nkag siab cov kev sib txawv no yog qhov tseem ceeb rau cov engineers, cov neeg yuav khoom, thiab cov thawj coj ua haujlwm kom ntseeg tau tias txoj kev xaiv zoo.
Dab tsi yog teem sijhawm 20 steel yeeb nkab
Teem caij 20 cov kav hlau hlau yog cov cim los ntawm lawv cov phab ntsa nyias nyias piv rau cov txheej txheem kav siab dua. Lawv tau sib dua hauv qhov hnyav, yooj yim dua los lis, thiab feem ntau tsis kim. Txawm li cas los xij, lawv lub phab ntsa thinner kuj txhais tau tias lawv tsis tuaj yeem tiv taus ntau lub siab siab. Vim li no, lub sijhawm 20 feem ntau siv hauv cov khoom siv tsawg- qhov kev siv dej, thiab tej lub teeb pom kev zoo {}
Vim tias nws thinner phab ntsa, lub sijhawm 20 muab ib qho loj dua lub cheeb tsam piv rau kev teem sijhawm 40 nyob rau tib lub peev xwm loj, uas tuaj yeem ua rau muaj peev xwm ntws tsawg. Qhov no ua rau nws txaus nyiam hauv cov ntawv thov uas ntws ua hauj lwm zoo yog qhov tseem ceeb tshaj qhov kev tiv thaiv siab tiv thaiv.
Dab tsi yog teem sijhawm 40 yeeb nkab
Teem sijhawm 40 yog ib qho ntawm feem ntau dav siv cov khoom siv roj hauv ntiaj teb. Cov kav dej no muaj cov phab ntsa tuab dua li teem sijhawm 20, ua rau lawv muaj zog dua thiab muaj peev xwm ntau dua nrog nrog nrog siab dua siab thiab kev ntxhov siab. Lawv feem ntau yog tsim hauv cov hlau roj carbon thiab hlau thiab siv hauv kev lag luam xws li cov roj thiab roj, kev ua haujlwm, thiab kev kho cov dej.
Vim yog lawv qhov sib npaug ntawm lub zog thiab tus nqi, teem sijhawm 40 kav yog suav hais tias yog "tus qauv" hauv ntau qhov kev lag luam. Lawv muab cov sijhawm ruaj khov rau ob qho chaw nyob thiab cov khoom lag luam luam ntawv. Cov phab ntsa tuab dua tseem tso cai rau lawv kom ua cov xov, grooved, lossis welded nrog kev ntseeg siab ntau dua, muab ntau yam lus rau kev teeb tsa.
Kev sib piv sab nraud thaum teem sijhawm 20 thiab sijhawm 40
Cov lus hauv qab no qhia tau qhov sib txawv ntawm cov sijhawm 20 thiab sijhawm 40 kav hlau hauv xaiv nominal. Phab ntsa tuab thiab qhov hnyav nce qis dua nrog cov sij hawm 40, thaum lub cheeb tsam sab hauv yog me ntsis ntawm cov kauj ruam 20.
| Nominal yeeb nkab loj (nps) | Sijhawm 20 Phab Ntsa Thickness | Teem Sij Hawm 40 Phab Ntsa Thickness | Teem caij 20 txoj kab saum qaum | Teem sijhawm 40 txoj kab sab hauv |
