ʻO Galvanized Steel Electrical Metallic Tubing (EMT) he ala uila maikaʻi loa e hoʻohana ai i kēia manawa ma ka mākeke.

Hana ʻia ʻo EMT me ke kila ikaika kiʻekiʻe, a hana ʻia e ke kaʻina hana kuʻi uila.

ʻAʻole kīnā ʻole ka ʻili o loko a me waho o ka EMT me kahi wili wili maʻemaʻe, a ua uhi pono ʻia me ka zinc me ka hoʻohana ʻana i ke kaʻina hana galvanizing wela, no laila e hāʻawi ʻia ka hoʻopili metala a me ka pale galvanic i ka corrosion.

ʻO ka ʻili o ka EMT me kahi uhi uhi post-galvanizing e hāʻawi i ka pale hou aku i ka ʻino. Hāʻawi ka ʻili o loko i kahi heihei hoʻomau maʻalahi no ka huki uea maʻalahi. ʻO kā mākou EMT conduit he ductility maikaʻi loa, e hāʻawi ana i ke kuʻi like ʻana, ʻoki i ke kula.

Hana ʻia ʻo EMT i nā nui kālepa maʻamau mai ? i ka 4". Hana ʻia ʻo EMT ma nā lōʻihi maʻamau o 10' (3.05 m). ʻO ka nui o ka pūʻolo a me ka pūʻolo haku e like me ka papa ma lalo. ʻIke ʻia nā pūʻulu o ka EMT i hoʻopau ʻia me ka lipine coded color no ka ʻike maʻalahi o ka nui.

Nā hiʻohiʻona a me nā pono
