If you’ve ever worked with pipes, then you know that offsets can be tricky to figure out. Luckily, we’ve created this rolling offset calculator so that you don’t need to worry about getting your calculations wrong. Just enter all of the information in, and we’ll do the rest!

What is a pipe?

A pipe is a cylindrical piece of material, usually made of metal or plastic. Its purpose is to transport fluids, gases, and solids like slurry. Many different industries rely on pipes for their operations: oil and gas pipelines, water supply systems, chemical plants, and sewage are just some examples.

Pipe offset

Offset is the distance between the center of the pipe and the center of the roller.

The offset is measured in inches, and it is measured from the center of the roller to the center of your pipe.

Rolling offset

The rolling offset is the distance between the centerline of the pipe and the centerline of the rolling tool. It is measured in inches.

The rolling offset is a function of both tool size and pipe diameter; if you change either, it will affect your rolling offsets as well. The larger your rolling tools or smaller your pipe diameter, the smaller your offsets will be.

If you’re building a house, you may need to know how to calculate rolling offsets. A rolling offset is the amount of additional space needed between two pipes in order for them to be able to roll around each other without touching.

For example, if your pipes are going through an area where they come close together and then go back apart again (i.e., they roll), then these offsets are important so that the pipes don’t touch each other when they turn or flex in different directions.

This calculator can help you figure out your rolling offset by finding out how much space is required between two pieces of pipe so that they don’t rub against each other while moving around freely in their environment (i.e., have room to “play”).

How to use the rolling offset calculator

This tool is useful because you don’t need to know any formulas in order to calculate the rolling offset. First, you need to enter the horizontal (h) and vertical offsets (v).

Degree rolling offset

As we can see from the diagram above, the horizontal and vertical offsets are the catheti of a right triangle, with the hypotenuse being the true offset (c).

The last thing you need to pick is the fitting bend (in degrees), and the calculator will give you the length of T.


What is rolling offset in piping?

A rolling offset is a length that connects two disjointed pipes.

What is offset bend?

An offset bend is a style of bend that is built independently of the 90° stub and the Back to Back bend and is an important bend to know when running conduit.

What is a 45-degree bend?

The Bend 45 is a Silent Plus SWR pipe fitting connecting two sewage pipes or pipes with fittings in the plumbing system.
