Steel Conduit Pipe Electrical EMT
I-Metallic Tubing yoMbane
Ityhubhu yentsimbi yombane (Emt Pipe), ekwabizwa ngokuba yi-thin-wall, yindlela yogqatso yentsimbi edwelisiweyo yecandelo lomnqamlezo ojikelezayo, ongafundwanga, kwaye ubizwa ngokuba yi-10′ ubude.20′ ubude nazo ziyafumaneka.I-EMT ifumaneka ngobukhulu borhwebo 1/2” nge-4”.Umphandle ufakwe igalvan ukuze ukhusele umhlwa kwaye ngaphakathi une-organic corrosion resistant organic coating.I-EMT ifakwe ngokusetyenziswa kwe-set-screw okanye i-compression-type couplings kunye nezihlanganisi.Ivumelekile ukuba ibe nodibaniso oludityanisiweyo olubandakanya ityhubhu eyandisiweyo, "belled" emilo kwelinye icala elinezikrufu ezimiselweyo.I-EMT ene-integral couplings ifumaneka kwiisayizi zorhwebo 1-1 / 4 nge-4.
