Hydrostatic test according to ASTM B 163
Hydrostatic test according to ASTM B 163
(OP)
Hi everyone,
I have an inquiry directed mainly to those that are familiar with ASTM B163 (or ASME SB-163).
In the hydrostatic test point it is indicated that the tubes shall be tested at a pressure of 1000 psi provided that the fiber stress wich is indicated in the same standard is not exceeded. Up to this point I understand that the test pressure should be 1000 psi or less.
When referring to U-bent tubes, the following is indicated: "The required fiber stress for computing hydrostatic test pressure shall be 26 600 psi"
My question is, in U-bent tubes is the test pressure still 1000 psi (or less) and the 26600 psi just are a new limit that I should not exceed when testing at 1000 psi? or the hydrostatic test pressure shall be calculated using the 26600 psi?
Thanks in advance

RE: Hydrostatic test according to ASTM B 163
How is the hydro sections fro the utube worded exactly.
There is usually an equation, and and the stress limit (26600), and they often restate a max test pressure.
Is there any ref to a max test pressure in the utube test section?
I don't have a current copy of B163 to check against.
