Insert the conduit in the bender and look for three notches on it next to a "center bend" mark that looks like a semicircle with an arrow at the center. These notches correspond to 30º, 45º, and 60º angles. Line up the appropriate mark (in this case 60º) with the center mark on your conduit.

How do you bend conduit?

Use a conduit reamer or knife to scrape the edges to get rid of any fragments, or burrs. Ensure that all burrs are removed before you install the conduit. Otherwise, this may cause a short or ground fault after the wire has been installed. Work with a bender. A bender is an essential for any conduit bending project.

How do you find the bend of a pipe?

Most bends other than 90° can be calculated using the geometry of a triangle. The black line represents an offset bend in a tube; the red triangle represents the triangular geometry this offset creates. The lengths/sides of the triangle are labeled “a,” “b,” and “c”. The “d” represents the angle at which the pipe is bent.

How do you find the center line radius of a bend?

A simple way to determine the center line radius of a bend of a specific angle is calculate a full circle, then divide that number by 360 to find the measurement of one degree. Then, use this formula: π (2r) or πD

How important is the angle on a bend in Conduit?

Of course, sometimes getting the exact angle on a bend isn't important; but often, whole conduit systems will be thrown out of whack if just a single angle is off 5°. Take your time to make sure the bends are aligned. This is particularly important on conduits with multiple bends. Be careful about creating a dog leg when you shape conduit.

How do you find the bend radius of conduit?

The minimum bend radius formula is: L = A/360° x 2πr. Using this formula, the minimum required length of a hose can be determined for any situation. When calculating the length oa hose assembly, the length of the fittings must be considered.

How do you measure the offset of a conduit bend?

When measuring for a rolling offset, place the tape measure from one conduit to the other at right angles to the conduit. Take a measurement from a point on the first conduit to the equivalent point on the second. This usually means measuring from one side instead from the top or bottom.

Do you add or subtract when bending conduit?

Decide how far back to make the first bend so that the conduit will miss the obstruction if bent at 45 degrees. Just a little practice here and you will become quite proficient at making this call. Deduct that measurement from the one to the wall and then subtract 1 more inch.

So when you take your over level length of pipe which in this case was 60 inches make it mark 5 inches from the edge and bend it you will get a 10 inch stub.

How is bend measured?

Use the correct formula to calculate the circumference of the bend. For example, the formula used when making a 90˚ bend is: Circumference = (pi*2*r) / (360/90). When bending, take into account the ability of the material to bend and sustain the bend. It should also not break during the process or later in application.

What is the take up on a 90 degree bend?

Take-up is a constant, and changes only with pipe size. To bend a ninety degree bend, you first determine your desired stub height. Then, you subtract the take-up for the size pipe that you are bending from the desired stub height and mark the pipe. Then, using a tape measure, measure from the end of the pipe back 10”.

How many bends are allowed in conduit?

No section of conduit shall contain more than two 90-degree bends, or equivalent between pull points. For conduits with an internal diameter of 2 inches or less, the inside radius of a bend in conduit shall be at least 6 times the internal diameter.
