Intermediate Metal Conduit

IMC was developed in the 1970s as a thin-wall alternative to rigid metal conduit (RMC) that weighs about one-third less. IMC ships with either a straight-tapped or integral coupling. It features a galvanized OD and corrosion-resistant ID coating.

Applicable Tolerance:

Wall Thickness: +0.015”(+0.4 mm) or -0.000” (-0.0mm)

There is no specific wall thickness or tolerance for rigid conduits

The only specification available are those in the National pipe standard specifications for Steel Pipe (A-120)

Length:±1/4 in (6.4mm)

Standard: UL1242

Finishes: Hot-dip Galvanized, Zinc Plated, Pre-galvanized

Ends of pipe: One side threaded with coupling, one side with plastic cap

Minimum quantity or order: 10Mt

Loading Port: Tianjin Xingang Port, China

Package:

1.Big OD: in bulk;

2.Small OD: in bundles, packed by steel strips;

3.Waterproof package with plastic cloth;

4.Standard export package;

.5.According to customers’ requirements.

IMC Sizing

IMC is available in trade sizes 1/2 through 4, and 10′ lengths. Threads on the uncoupled end are covered by industry color-coded thread protectors to protect the threads, keep them clean and sharp, and aid in trade size recognition.

Using IMC as a Substitute for RMC

IMC is interchangeable with galvanized RMC. Both have threads with a 3/4-inch-per-foot taper, use the same couplings and fittings, have the same support requirements and are permitted to be used in the same locations.
