Dear All,
for moderate pipeline inventory where liquid thermal expansion as a result of solar ambient radiation , API 521 section 4.12.3 is stating a TERV size of 3/4'' x 1''
Do you agree that such size is not certified by API 526 nor further by ASME and hence a minimum of 1 D 2 size shall be considered instead?
is 3/4'' x 1'' purposely mentioned for piping systems and NOT for vessels considering ASME SEC VIII capacity certification requirement is for pressure vessels and not for piping system?
Kindly please appreciate your advice on when to consider 3/4'' x 1'' and whether such Thermal TSV shall follow API 526.
Thanks
