VDI 2263 Part 3 deals with this ... ■
Re: Atex And The Pressure Equipment Directive
The title says, “pressure shock resistant vessels and apparatus calculation, construction and tests”.
If you are designing the vessel for containment then you will need to calculate the max design pressures, safety factors etc. This deals with it. ■
Re: Atex And The Pressure Equipment Directive
Yes, but we still have to deal with a high profile client who is stating that he regards it as coming within the requirements of the PED and shall be supplied CE marked accordingly. Tempted to decline to offer a quotation due to the level of technical risk. ■
Re: Atex And The Pressure Equipment Directive
Well all pressure vessels in PED which do not fall under sound engineering practice will have to be CE marked any way. Since P max value is normally above 6 bar so all the containment vessel do fall under PED.
Only difference with pressure shock resistance method is that the vessel is designed according to the max achievable explosion pressure. This is calculated using the above mentioned VDI code buy taking into account normal working pressures and P max of the material etc. You can do the sums before any vessel drawings / design is done. Get the client to agree with it and then design the vessel according to PED to contain max achievable explosion pressure. Only thing is stick to VDI code as it is easy to work with as compared to latest NFPA code. ■
ATEX and the Pressure Equipment Directive
It is being suggested by an end user that equipment conforming to ATEX must also conform to the Pressure Equipment Directive since it is being designed to contain a pressure. I thought that this was NOT the case, but currently have mislaid my reference data.
Can anyone provide clarification, with references, as to which is correct. ■
