Hlau Conduit Yeeb Nkab Hluav Taws Xob EMT
Hluav taws xob hlau tubing
Hluav taws xob hlau tubing (Emt Tub), kuj feem ntau hu ua nyias-phab ntsa, yog ib qho kev sib tw steel ntawm txoj kab hla hla, uas yog unthreaded, thiab nominally 10′ ntev.20′ ntev kuj muaj.EMT muaj nyob rau hauv kev lag luam loj 1/2 "mus txog 4".Sab nraud yog galvanized rau kev tiv thaiv corrosion thiab sab hauv muaj kev pom zoo corrosion-resistant organic txheej.EMT yog ntsia los ntawm kev siv cov ntsia hlau los yog compression-hom couplings thiab connectors.Nws raug tso cai kom muaj ib qho kev sib txuas ua ke ntawm kev nthuav dav, "belled" lub raj ntawm ib kawg nrog cov ntsia hlau.EMT nrog ib qho kev sib txuas yog muaj nyob rau hauv kev lag luam loj 1-1/4 txog 4.
