Multiplier for 15 degree bend

On page the shrink for offsets is given as hypotenuse - side adjacacent. The side adjacent is AB. For convenience this is called the geometric shrinkage. Distance BC is the height and angle 2 is the offset bend angle. Distance AB can be found by:. The values for this shrinkage multiplier are constant for given angles and does not vary for different radii or heights. The third shrinkage multiplier are those given in Zip tables found in handbooks and manuals and largely the result of Benfield's Tables as published in the Benfield Conduit Bending Manual. These values are shown in Table 1. These values are constant and do not vary with a change in radii or height. These values assume that there are no bends or arcs in the offset, and that the conduit follows a broken straight line path which it doesn't. These shrinkage multiplier values can be calculated using the calculator below by setting the radius to 0 and adjusting the angle. A change in height does not effect the calculated shrink multiplier while the radius is set to zero.

Below are four charts made using an Excel Spreadsheet showing some typical differences in the three Shrinkage Multiplier Values. Waste less bends?

Trigonometry, is a branch of mathematics specifically dealing with the sides and angles of triangles. Trigonometry is a key part of conduit bending. Fortunately every type of bend is based off of a right triangle. There's three basic formulas for trigonometry. The values of these formulas play a huge role in determining the unknown sides and angles of a triangle.

Master conduit bending techniques, , and calculations with our comprehensive cheat sheet. Learn the basics, types of conduits, tools required, and for efficient and accurate bending. Conduits are typically made of materials such as metal or plastic and come in various sizes. Here are a few common types of conduits:. These tools are designed to help you achieve accurate bends and ensure the safety of the installation. Here are some of the key tools required for conduit bending:. Here are some essential to keep in mind when bending conduits:. By understanding the basics of conduit bending, knowing the different types of conduits, having the necessary tools, and following , you can confidently tackle conduit bending projects with precision and efficiency. When it comes to conduit bending, one of the key factors to consider is the bend radius. The bend radius refers to the minimum radius that a conduit can be bent without causing damage or compromising the integrity of the conduit.

Or trapezes On offsets make sure you are measuring from botttom-to-bottom and on 90's the measurement should be to the back of the bend. Search Advanced search…. Click to expand The shrink constant is a multiplier to determine the amount of conduit that's lost after the bend is completed Shrink. Sign up. Assume that we have a piece of 4 inch conduit Simply enter the height and radius and charts for other values will be calculated for you. Thread starter sundowner Start date Oct 4, The new linear length is 40 inches see below. Enter decimal number with keyboard or use display. Yes if I try for a 11" 90 I get probably around

But what happens when you need to bend them at an angle? In this article, we will discuss what multipliers are, why they are important for degree bends, and how to use them effectively. Think of a multiplier as a tool that helps you calculate the length of the tube you need to create a bend.

Edit this page. Thanks Steve. Last edited: Oct 5, Or trapezes Distance BC is the height and angle 2 is the offset bend angle. Calculator by electrician2. Location Iowegia. Find another way if at all possible. Any of you guys who run conduit a lot, make your 3 bend saddles using 15,30,15 degree bends? My real deal is that I sorta like to only make saddles with my bender going one way-- ya remember from apprentice school the multiplier of three if your to do it this way.. Location Owego, NY. Developed Length Calculator. That way it doesn't matter which size pipe you are using, the multiplier is still going to be two. QuickBend Docs. These shrinkage multiplier values can be calculated using the calculator below by setting the radius to 0 and adjusting the angle.
