Steel Conduit Pipe Electrical EMT
I-Electric Metallic Tubing
Amashubhu ensimbi kagesi (Emt Pipe), evame ukubizwa ngokuthi i-thin-wall, iwumzila wensimbi esohlwini lwesigaba esiphambanayo esiyindilinga, esingafundiwe, futhi ngobude obungu-10′.20′ ubude buyatholakala.I-EMT itholakala ngosayizi bohwebo 1/2” kuya ku-4”.Ingaphandle ifakwe uthayela ukuze kuvikeleke ukugqwala futhi ngaphakathi kunento ephilayo ekwazi ukumelana nokugqwala.I-EMT ifakwa ngokusetshenziswa kwe-set-screw noma ama-compression-type couplings nezixhumi.Kuvunyelwe ukuthi kube nokuhlanganisa okubalulekile okuhlanganisa ishubhu lomumo “obelled” onwetshiwe kwelinye icala elinezikulufu ezimisiwe.I-EMT enokuhlanganiswa okubalulekile iyatholakala ngosayizi bohwebo 1-1/4 kuya ku-4.
