   U.S. CUSTOMERY EQUATION P = 2ST/D

  WHERE:
  P = Hydrostatic Test Pressure Psi
  S = Fibre Stress Psi
     = 60% of min. Yield Strength for standard
             Test Pressure
        Or 75% of min. Yield Strength for
             alternate Test Pressure

  T = Specified Wall Thickness inch (mm)
  D = Specified Outside diameter inch (mm)

 TEST PRESSURES ARE NORMALLY LIMITED TO
  3-1/2 inch OD & smaller (Grade A & B)  : 2500 Psi
  Larger than 3-1/2 inch OD (Grade A & B): 2800 Psi
  All OD sizes (Grade X42 - X60)             : 3000 Psi
