Copper Pipe Pressure Calculator
Here’s a table with the pressure ratings (in psi) for different types and sizes of copper pipes at 100°F:
| Pipe Size (inches) | Type K (psi) | Type L (psi) | Type M (psi) |
|---|---|---|---|
| 1/4 | 1,530 | 1,090 | 1,000 |
| 3/8 | 1,330 | 1,020 | 840 |
| 1/2 | 1,190 | 910 | 770 |
| 3/4 | 1,050 | 850 | 690 |
| 1 | 990 | 810 | 630 |
| 1 1/4 | 850 | 750 | 560 |
| 1 1/2 | 810 | 690 | 510 |
| 2 | 750 | 640 | 470 |
These estimations are based on typical pressure ratings for copper pipes used in plumbing applications. Note that actual pressure ratings can vary based on specific manufacturing standards and conditions. Always refer to the manufacturer’s data for precise values.
