![]() In addition, it does not account for the strain-hardening characteristics of copper tube that can increase the strength (true stress) over seven times. The downside of utilizing this calculated pressure rating is that it underestimates the actual safe performance of the tube since it is overly conservative when applied to thin wall tubing (where the diameter to wall thickness ratio is greater than 10) like the commercially available copper tubes covered in this handbook. The allowable stress value depends on the service temperature and on the temper of the tube, drawn or annealed. It is only a small fraction of copper's ultimate tensile strength or of the burst strength of copper tube and has been confirmed to be safe by years of service experience and testing. The value of S in the formula is the maximum allowable stress (ASME B31) for continuous long-term service of the tube material. ![]() C=a constantįor copper tube, because of copper's superior corrosion resistance, the B31 code permits the factor C to be zero. P=allowable pressure, psi S=maximum allowable stress in tension, psi t min=wall thickness (min.), in. Rated Pressures Based on CalculationĪs for many piping materials, the calculated allowable internal pressure for copper tube in service is commonly based on the formula used in the American Society of Mechanical Engineers Code for Pressure Piping (ASME B31): These generally require more extensive testing across the product size range and anticipated stress/strain regimes than the calculated methods, but can provide more accurate and robust ratings. However, pressure ratings based on actual material performance may also be developed and used. Oftentimes this is preferred since it reduces the amount of testing required. These include calculated ratings based on basic material properties, such as tensile and yield stress, piping dimensions and engineering correlations. There are various methods for determining the recommended, allowable or rated internal pressure-temperature ratings for piping materials and systems.
