Cov hlau nruab nrab kav dej ( IMC ) yog steel tubing hnyav dua EMT tab sis sib dua RMC. Nws tuaj yeem yog threaded. Hluav taws xob hlau tubing ( EMT ), qee zaum hu ua nyias-phab ntsa, feem ntau yog siv los ntawm galvanized rigid kav dej (GRC), vim nws tsis tshua muaj nqi thiab sib dua li GRC.
Tsuas yog li ntawd, IMC conduit siv rau dab tsi?
Cov hlau nruab nrab kav dej , los yog IMC , yog cov khoom siv hluav taws xob tsis zoo kav dej tsim rau sab nraum zoov raug thiab muaj zog sib txuas. Nws tau tsim tshwj xeeb los tiv thaiv insulated hluav taws xob conductors thiab cables. Nws ua haujlwm ntawm cov hlau zoo sib xws kav dej , tawv hlau kav dej ( RMC ), tab sis hnyav txog ib feem peb tsawg dua.
Ib yam li ntawd, hom conduit yuav tsum siv sab nraum zoov? Nonmetallic cev is feem ntau yog ua los ntawm PVC thiab yog xaiv zoo rau sab nraum zoov daim ntawv thov nyob. Xiav hluav taws xob tsis yog hlau tubing (ENT) yog rau sab hauv tsev siv nkaus xwb.
Ua kom pom qhov no, hom hlau twg yog EMT txuas?
Electrical Metallic Tubing-EMT Lwm qhov piv txwv ntawm cov khoom siv hluav taws xob nruj yog EMT (hluav taws xob hlau tubing), uas feem ntau ua los ntawm galvanized hlau tab sis kuj tuaj yeem yog txhuas. EMT tseem hu ua "thin-wall" conduit vim nws yog nyias thiab hnav, tshwj xeeb tshaj yog piv rau RMC.
Kuv tuaj yeem siv EMT conduit qhov twg?
Flexible hlau kav dej yog qhov zoo rau thaj chaw uas yuav tsum tau khoov nruj thiab cov chaw kaw yuav ua rau nws nyuaj rau khoov tsis tu ncua kav dej . Cov cua kub cua sov, lub teeb tuaj yeem, thiab cov qhov cua hauv qab yog cov piv txwv zoo ntawm kev hloov pauv tau yooj yim kav dej kev teeb tsa EMT cev yog lub teeb yuag, yooj yim khoov, thiab siv sab hauv phab ntsa.

Dab tsi yog qhov txawv ntawm qhov ua tau zoo thiab cov khoom lag luam teb thiab cov ntsiab lus ntawm kev lag luam uas txhua qhov ua haujlwm zoo tshaj?
Lub tuam txhab muaj peev xwm ua kom tau raws li cov neeg siv khoom xav tau raws sijhawm yog hu ua Kev Ua Haujlwm Zoo, thaum ua haujlwm tau zoo yog lub tuam txhab muaj peev xwm xa khoom raws li tus neeg siv khoom xav tau nrog tsawg kawg ntawm cov khoom siv raw, kev ua haujlwm thiab tus nqi
Dab tsi yog qhov txawv ntawm qhov point thiab nonpoint qhov chaw ntawm dej paug?
Piv txwv li, cov dej tso tawm los ntawm cov chaw tsim khoom lag luam ntawm qee yam lossis cov chaw kho dej khib nyiab. Cov chaw uas tsis yog cov ntsiab lus suav nrog kev khiav tawm ntawm thaj av ua liaj ua teb uas tuaj yeem ntxuav cov chiv lossis lwm yam tshuaj rau hauv pas dej lossis dej ntws - qhov no yuav tshwm sim ntau txhiab square kilometers
Dab tsi yog qhov txawv ntawm qhov rov qab los ntawm peev thiab rov qab los ntawm peev?
Ua ntej, qee qhov kev txhais. Rov qab los ntawm peev ntsuas qhov rov qab uas qhov kev nqis peev ua rau cov neeg koom nrog peev. Rov qab los ntawm peev (thiab ntawm no Idiffer nrog qee cov ntsiab lus) yog thaum tus neeg ua lag luam tau txais ib feem ntawm nws cov peev txheej qub rov qab - suav nrog cov nyiaj tau los ntawm cov nyiaj tau los - los ntawm kev nqis peev
Dab tsi yog qhov txawv ntawm qhov cuam tshuam qhov (socket) thiab lub qhov (socket) pa?
Rau kuv qhov kev paub qhov sib txawv yog nqes mus rau cov khoom siv Qhov saum npoo-hardening ua rau muaj kev cuam tshuam cov qhov (socket) kom nqus tau qhov hloov pauv tam sim ntawd (aka 'kev cuam tshuam') zoo dua. Nrog rau kev cuam tshuam txaus txaus, lub qhov (socket) tsis tu ncua tuaj yeem tawm ntawm cov duab vim tias cov hlau siv muaj softer
Dab tsi yog qhov txawv ntawm qhov kev thov thiab qhov xav tau ntawm cov khoom hais tias mis nyuj?
Dab tsi yog qhov txawv ntawm qhov kev thov thiab qhov xav tau ntawm cov khoom, hais mis nyuj? Kev xav tau yog kev sib raug zoo ntawm ntau tus nqi thiab qhov xav tau ntawm cov nqi ntawd. Kev xav tau ntawm cov mis nyuj yog qhov kev sib raug zoo ntawm tus nqi sib txawv ntawm cov mis nyuj thiab qhov xav tau ntawm cov nqi ntawd
