*Reference:
Pressure data for metal tubing is taken from American National Standard Code for Pressure Piping, “Power Piping, ANSI B31.1 – B30-1993AEdition.” The values stated for operating (opr.) pressure are the maximum internal service pressure determined using the calculated burst pressure and an associated design factor. The equations and stress values were extracted from the above listed document. -
-
Burst Pressure = K d-0.8t
Where K=efficiency of weld (0.85);
(K=1 for seamless)
s=tensile strength of stainless steel (PSI)
D=tube O.D. in inches
t=tube wall thickness in inches
- the operating pressure is taken to be 25% of the burst pressure, which is a 4 to design factor.
