PED is not only about stamp. The conformity assessment procedures to be applied to an item of pressure equipment shall be determined by the category as set out in Article 13 of the PED and the Module(s) shall be determined in accordance with Annex III.

PED is not a design code, you may use an Harmonized Standard (such as EN 13445) but, you can use any other design code as you want, provided that you comply with the ESR (Essential Safety Requirements) set forth in ANNEX I of the PED. ASME is a Construction Code, which deals with materials...

PED 2014/68/EU applies to the design, manufacture and conformity assessment of pressure equipment and assemblies with a maximum allowable pressure greater than 0.5 barg. PED is a law made to eliminate the technical barriers across the EU, it does not impose detailed technical solution nor design...

General Note (b) refer to Mandatory Appendix 1, 1-4(b).

Read ASME VIII-1, U-4. Especially U-4(g), that shall answer all of your questions.

I participated in three audits conducted at the factory where I work, during none of them was I asked to present a licenses for the softwares I use (SW, MathCAD and more) With that being said, I strongly advise against trying to outsmart anyone.

1. It is beneficial to find mentors who are knowledgeable about the Code. Throughout my career, I have had the privilege of having three mentors who guided me through the intricacies of the Code. 2. Approach the ASME Code with a contextual mindset, Merely reading the Code without considering...

This material is defined as P-No. 8 and Group No. 1. According to ASME VIII-1, Table UHA-32-3, PWHT is neither required nor prohibited for joints between austenitic stainless steels of the P-No. 8 group.

The Base Metal P-Numbers and Group Numbers are shown on ASME IX, Table QW/QB-422. Change in the Group Number is define as a Supplementary Essential Variables. Those variables become additional essential variable in situation were the referencing code, requires toughness testing. See QG-105.3 and...

Does re-rating of the vessel is something you can do? Perhaps 219.8 would be enough?

You need to distinguish between two things. You were asking about pressure vessel design by ASME VIII-2. U2 and CE (in some cases) are required for pressure vessel constructed to ASME VIII-2. Note that the the word "Construction" is an all-inclusive term comprising materials, design...

Just to clarify - the Manufacturer Design Report shall be certified by CE when any of the design acitivies set forth in VIII-2, 2.3.3.1 are performed.

XL83NL you are mixing CE (European Conformity) which is needed for vessels located in the EU and CE (Certified Engineer) which is needed if the fatigue assessement is needed as part of the vessel design. OP, if the vessel is only "designed" per ASME VIII-2 you don't need anything. But, if the...

Thank you very much

Christine74, Only Unfired steam boilers can be constructed by VIII-1. Only electric boiler where the medium (water) is directly heated by the energy source (electrode type or electric immersion element type) is considered to be an unfired steam boiler and hence, may be constructed by VIII-1...

It is recommended to take a look at AB-520 which provides information regarding the use of FEA in to support a pressure vessel design. It also provide guidelines on how the report should look like, and what shall be included...

I don't know how it works in ANSYS but my software gives a solution error and analysis stops.
