PED 97/23/CE substitude with ASME VIII

[Elnur250774]

We have a bid to build Air Heater Drum in accordance with PED 97/23/CE. I am not familiar with this standard but would like to suggest to substitute it with ASME VIII. Could anyone advise whether it would be acceptable and do I need to bring ASME inspector (authorization body) to approve it as we are not pressure vessel fabricator.

Operating characteristics are:
Inner fluid: saturated steam and water
Operating temp.: 130 to 160 deg C
Operating pressure: 2 to 6 bar g
Design temp.: 300 deg C
Design pressure: 10 bar g

Thanks in advance.

Where will you supply the vessel for? If you ship it to Europe, you will need certification acc. to PED 97/23/CE. ASME is fine but in this case no substitute.

Vessel will be used in Azerbaijan and we are also located in Azerbaijan.

If you are not pressure vessel fabricator, how could you build to ASME Section VIII Div I? Are your shop (where the product will be built) ASME "U" stamp holder?

 

[Elnur250774]

No, we aren't "U" stamp holder, but in the past we built pressure vessels in accordance with ASME VIII Div 1 and that time we brought ASME inspector from authorisation body (ABS).

Whether you have to fullfil PED or ASME depends upon the laws and rules in Azerbaijan and upon the request of your customer. Concerning safety and technical rules ASME is not worse than PED or vice versa.

ASME VIII and PED are not the same sort of thing - if you are familiar with ASME VIII and read the PED you will see what I mean. This link may not be up-to-date, but it is a good start.

Look at section 2.2.3(a). You can most likely use ASME VIII design rules to help you towards PED compliance, but the design is only a very small part of PED requirements.

PED (97/23/CE directive) is NOT a design code

As others have said ASME cannot substitute for PED. PED is law in the EEC and not a design code. We're finding that our customers in Eurasia are requiring it as well. ASME can be used as a basis for conforming to PED.

ASME has a guide you can purchase...
