Hi,
I have a tank made from carbon steel type SA516 Gr. 60 with thk. = 10 mm (0,4 inch). The question is, heat treatment for welds of the tank shall be applied or not?
Hi.
I would like consult an expert.
I check the design of ball valve different types.
One of them is for preinsulated bonded pipe systems for directly buried hot water networks acc. to EN 488.
Mentioned standard says that valves shall withstand the load comes from axial forces (tensile stresses...
Is it right to determine pressure test value acc. to AD 2000 Merkblatt last edition (to satisfy PED requirements) for heat exchangers type of AET or AES (and the others) taking into consideration not only shell and heads but also main flanges and their bolts as pressure parts? This situation...

Following your knowledge and experience please tell me what do you think about following case:
- Pressure vessel is designed according to AD 2000 Merkblatt
- Materials are taken from AD 2000 (part. W4 for nozzles pipes);
- min. operating temperature TS is –29 degree of Celsius
Shall be or not...
How should be determinate pressure test value (PT) for carbon steel pressure vessel calculated acc. to ASME code + PED? It means expression f20/ft in equation PT=1.25.PS.f20/ft. Should this expression (f20/ft) be calculated acc. to ASME code or PED 97/23/EC annex 1 p.7 (min. [Re/1.5; Rm/3.5] or...
