How much will 2" tubing gain for every 90-degree bend?

The correct value for how much 2" tubing gains for every 90-degree bend is typically around 3/16 inch. This measurement is critical in pipefitting and instrumentation work because bends in tubing can affect the overall length of the installed piping.

When bending tubing, the tubing tends to "pull" in a way that shortens its effective length within a system. This means that for every 90-degree bend, you generally should account for a reduction in the straight length of the tube. The gain measurement (in this case, 3/16 inch) represents how much material is effectively added during the bend to account for this shortening. Understanding this concept is crucial for accurate installation and alignment in instrument technician work.

It's important to note that the specific gain can vary depending on the diameter and wall thickness of the tubing and the radius of the bend, which is why knowing the standard gain for a specific size, like 2", is essential for precise calculations in fieldwork.
