For most tube bender radius blocks, a 90-degree bend typically gains approximately how much?

When determining the gain for a 90-degree bend in most tube bender radius blocks, understanding the relationship between the bend's radius and the diameter of the tube is crucial. A gain refers to the additional length added to the tube as a result of the curvature of the bend.

For a standard 90-degree bend, the gain is usually calculated based on the tube's diameter. The gain of approximately 1 tube diameter indicates that for every 90-degree bend made, the effective length of the tube increases by about the length equal to the diameter of the tube. This is a conventional measurement used in tubing applications, as it provides a clear and simple way for technicians to visualize how much extra length will be required for bends.

This information is particularly beneficial when laying out pipe or tubing runs, ensuring that there is enough material to account for the increased length from the bending process. Understanding this gain helps avoid issues that might arise from insufficient material when constructing or modifying piping systems.
