Formulas and Multipliers for Bending Conduit or Electrical Pipe Dengarden
The multiplier is the number of the measured distance of the offset it is multiplied by to obtain the distance between the two bends. You should memorize this number for the common bends of 10, 22, 30, and 45 degrees.

Using trigonometry to calculate conduit bending. Tue 25 September 2018. misc. The folks at Dengarden have a lot of conduit bending resources. If you're familiar with the way that conduit bending is usually taught, it's via shortcuts and rote memorization of how to do things like offsets, kicks, bends, etc. Suppose you studied trigonometry in.
Math formulas and multipliers to help you bend electrical conduit
Is there anyone who has the multiplier table for bending conduit? I would like to print out and laminate a copy of it in a pocket size format so I can start carrying it with me every day. Thanks Tools for Electricians: Tools for Electricians, Installers, Maintenance & Service Technicians

The stub bend is made by bending a piece of conduit into an L shape or 90ยฐ bend by placing the free end (short end) of the tube to a predetermined length as indicated in the diagram below. This is the most common bend and is a building block for other bends.

Conduit consists of metal pipes (often called EMT) through which the wires pass and it must be bent to go around any barriers it encounters. Conduit is a very efficient way to wire a working area because it directly attaches to the wall and does not require opening holes in drywall and repairing the damage.

Bending conduit is an integral part of an electrician's work, and this set of articles is designed to help electricians, whether a beginning apprentice or an experienced journeyman, learn how to bend conduit.
One of the more common bends made in electrical conduit is the offset
Compression fittings. Unidelta compression fittings and saddle clamps are specially designed for joining polyethylene pipes with an outer diameter between 16 mm and 110 mm (200 mm for saddle clamps). They are suitable for joining polyethylene pipes, both high and low density, in drinking water distribution systems at pressures of up to 16bar.

How to Bend an Offset in Conduit. An offset is a bending technique that turns a straight conduit into a Z-shape, which allows it to avoid obstacles and change elevation. Calculate and mark where the conduit will be bent. Line up the bender's arrow (B) with the first mark and with the tube on the ground, make a 45ยฐ bend. Turn the bender upside.
Conduit Offset Multiplier Chart
A Stub Up or "L" conduit bend is kind of bend that creates a vertical bend in conduit that is in an "L" shape. Decide the overall free end height you want once the bend is made Calculate the stub height by using the free end height and subtract the stub adjustment (from Bender Take Up Table below) 90 DEGREE STUB UP BEND - TAKE UP TABLE

Canva Math Used for Bending Conduit The math of conduit-bending that we will discuss here comes from two sources. Some of the math is already built into a common hand bender device, and the rest of it involves the geometry of a triangle. Note that making concentric bends requires using some additional math not discussed in this article.

QuickBend is an advanced conduit bending calculator that was created to be fast and accurate while being visually appealing, innovative, and intuitive. Offering you the most accurate measurements using the center-line radius algorithm based upon the bender that you're using.
Formulas and Multipliers for Bending Conduit or Electrical Pipe Dengarden
Multiplier (Cosecant) Method# Typically when bending conduit you decide the theta, and the hypotenuse (distance between bends) is the unknown value. In order to find these unknown values quickly by hand we'll use the multiplier method. This is the most common method to conduit bending. It uses the cosecant (1/sin) from the theta (bend).
Formulas and Multipliers for Bending Conduit or Electrical Pipe
This is the amount of straight conduit required to make the bend. Example: To make a 90ยฐ bend with a 4" center line radius: Multiply the radius (4") by 1.57 for the Dev. Length (6.28). Divide by one less than the amount of bends, for example 9 - 1 = 8 spaces. Bend 10ยฐ at each line. Dev Length = 1.57 x 4" = 6.28".
