Technical Data
Values of allowable internal working pressure for copper tube in service are basedon the formula from ANSI B31, Standard Code for Pressure Piping:
P = Allowable Pressure
S = Allowable Stress
Tm = Min Wall Thickness
DMax = Max Outside Diameter
@150°F S = 10,300 PSIG annealed
@200°F S = 10,300 PSIG annealed
@300°F S = 10,000 PSIG annealed
@400°F S = 9,400 PSIG annealed
All ratings listed for Halstead® Type L/ACR Nitrogenized Straight Lengths in the preceding chart, are calculated for tube in the annealed/hard condition. These values should be used when soldering, brazing, or welding is employed for joining components in a system. In designing a system, careful consideration should also be given to joint ratings, as well as those of the components
