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.
