A 45-degree elbow is a type of pipe fitting used to change the direction of a piping system by 45 degrees. It is typically used when a gentle bend is needed in the pipeline while maintaining a certain flow direction. The elbow is designed to connect two pipes or tubes at a 45-degree angle, allowing for a smooth change in direction.
Below is a dimension chart for a standard 45-degree elbow used in piping systems. The dimensions provided are general and may vary depending on the specific manufacturer and standards followed.
Please note that the dimensions are given in inches (") and are approximate. The values represent the nominal sizes.
| Nominal Pipe Size (NPS) | Outside Diameter (OD) | Center-to-Face (C) | Center-to-End (M) |
| 1/2 | 0.84 | 0.62 | 0.84 |
| 3/4 | 1.05 | 0.81 | 1.06 |
| 1 | 1.32 | 1.00 | 1.32 |
| 1 1/4 | 1.66 | 1.31 | 1.73 |
| 1 1/2 | 1.90 | 1.62 | 2.06 |
| 2 | 2.38 | 2.06 | 2.63 |
| 2 1/2 | 2.88 | 2.50 | 3.25 |
