SA-105 vs. SA-266 Cl. 2
In my opinion, SA-266 Cl. 2 is not allowed by Section VIII Div. 1, see Section II. B16.5 does not allow this material for flanges.- khp123

polythionic acids
The most common fluid causing intergranular corrosion in hydrocarbon plants is polythionic acid. Both austenitic and straight chromium grades of stainless steels can be attacked by polythionic acid. This phenomenon is usually an internal problem, occurring on the process-exposed side of a...- khp123

Can anybody highlight on dimensions of dishedend as per admerkblatter?
Designs per the AD-Merkblätter require the use of DIN materials. DIN materials may have different mechanical properties than ASME materials. Even when a DIN material is determined to be “equivalent” to an ASME material, one must be careful in its application. For example, the requirements for...- khp123

Mechanical Integrity
Section 2.3.3.5 of API 653 does allow for minimum required wall thickness calculation per Appendix 4 of ASME Section VIII, Div. 2. If your nameplate follows API 650, you can obtain most of the information that you will need to do your calculations here. Use the thicknesses obtained from the UT...- khp123

Flat Reinforced Tank Roof
In my humble opinion, API 650 does not disallow flat roof tanks. API 650 only provides four typical roof designs as detailed in Section 3.10. Because this is a flat roof tank, I will assume that the tank is not very large otherwise, you would have something like a cone roof tank. Your...- khp123
