Statuary Regulation governing the design of pressure vessel and heat exchanger

[Mech2325]

Hi all,

Can anyone tell how do the statuary regulations govern the design or fabrication of static equipment like heat exchangers and pressure vessels?

Design? In Europe, PED (Pressure Equipment Directive, 2014/68/EU) is the governing law that defines the minimum safety requirements for pressure vessels. This is for entering the marketplace only however. You can meet the requirements easily by using a harmonized standard, e.g. EN 13445 for unfired pressure vessels, or you can use a recognised standard and do additional steps to show that it is safe.
Once on site and in operation, in the UK it is PSSR 2000.

Well thank you for your response, but my question is, for example, you need to deliver some vessels and exchangers in alaska or algeria for a refinery being set up there. There is often mentioned in the order of precedence of design documents that the statuary regulations need to be taken care off in the project. My question is with this reference as to how should you take these regulations if you are a mechanical design engineer (process equipment)

Mech2325, in my experience it is fairly common to take exception to local regulations for vessels meeting a recognized Code of Construction such as ASME Sec VIII, Div 1 for example. In the US and Canada the local jurisdiction requirements are fairly easily determined thru NBIC, ABSA and so forth. For foreign jurisdictions, not so easily done.

Contract documents would state local jurisdictional regulations are not necessarily met.

On edit, the purchaser should have primary responsibility for insuring such are met, the seller, little to none.

The problem with sloppy work is that the supply FAR EXCEEDS the demand

The 'how do ...' is that certain countries/provinces/states explicitly spell out which codes needs to be followed, e.g. America and Canada. Europe on the other hand has the PED which as caloomi mentioned doesn't prescribe a specific design code, but just the minimum essential safety requirements.

Thank you all for your feedback

It is not stated where the final location of installation will be. If you are a ASME/NB Certificate holder I suggest you contact your AIA. Hartford Steam Boiler has a database for International Import Requirements which provides detailed information. The National Board also has NB-370 which provides those jurisdictional requirements for Canada/USA. It is free on their website

Certainly depends in what country the project is located. Here we have Earthquake design requirements that you will not find in any ASME or EU code. We also require 3rd party design checking by someone certified by the statutory body.

The purchaser needs to know the local rules and put these into the purchasing contract. Too late to comply when the vessels turn up on site. Suppliers need to be aware and ask for the local rules.

Mech2325:
Do the statues look like pressure vessels, or do the pressure vessels look like statuary? Any nudes? Is this an attempt to beautify refineries and the like?
