Electrical Metallic Tubing (EMT) Machine For Electrical Welded Pipe For Cable Protection

This RT50 Electrical Metallic Tubing (EMT) machine is to produce 1/2 to 2 inches round electrical welded pipes for cable protection

Product Details

Model: RT50 (63.5mm×2.5mm)

The RT50 EMT Galvanized steel pipe mill is intended for manufacturing of round pipe of Φ19mm-Φ63.5mm with Thickness of 0.8mm–2.5mm from galvanized coil strip. 

Brief Introduction for EMT Pipes

Electrical metallic tubing (EMT), also commonly called thin-wall, is a listed steel raceway of circular cross section, which is unthreaded, and nominally 10′ long. 20′ lengths are also available. Covered by Article 358 of the NEC, EMT is available in trade sizes 1/2 through 4. The outside is galvanized for corrosion protection and the inside has an approved corrosion-resistant organic coating. EMT is installed by use of set-screw or compression-type couplings and connectors. It is permitted to have an integral coupling comprised of an expanded, “belled” shape tube on one end with set screws. EMT with integral couplings is available in trade sizes 1-1/4 through 4.

Features of RT50 Pipe Making Machine

This RT50 Electric pipe making machine is used to produce straight seam automatic EMT pipes tubes by means of steel slit strips with its subsequent welding into tube, edge heating by means of solid state high-frequency welder, longitudinal straight seam welding in rolls of tube welding machine, as well as equips with inner side scraping unit, cooling, further sizing or shaping and on-stream cutting of endless tube in measured lengths.
