Pressure Equipment Directive
Pressure Equipment Directive
(OP)
The pressure equipment directive states "this Directive does not cover the assembly of pressure equipment on the site and under the responsibility of the user, as in the case of industrial installations"
What I wish to understand as an owner/operator of a chemical process plant in the European Union where I have employed an engineering design firm to design a piping installation, and then employ a contractor to fabricate/assemble the installation on site does the Pressure equipment directive apply or does the above extract from the directive exclude the PED from being applicable as the piping installation is effectively the "the assembly of pressure equipment on the site and under the responsibility of the user"
The PS.DN would be 2000 of this installation.
Thank you.

European Directives are focused to godos to be sold whithin the European Union.

Im no a subject expert but i use PED regularely.
If you look in the guidelines i think 3.2 will help a little. Guideline 3.8 then gives some more explanation as to the difference between components and pressure systems and assemblies and installations. Not knowing i think that this is legal stuff to make sure that a manufacture dosnt break some local regulation/law while referring to PED:
Question: Are joining operations on site covered by the PED?
Answer: For the joining on site of components or equipment, two cases have to be
considered:
1) Joining of component parts: joining of component parts to
comprise an item of pressure equipment is subject to the requirements of
the Directive. The manufacturer –even if he is the user- has the
responsibility that the resulting item of pressure equipment is in
compliance with the Directive.
2) Joining of items of pressure equipment.
The joining is not covered by the PED if it is carried out to constitute an
installation (1) under the responsibility of the user but remains covered by
national rules.
If the joining is carried out under the responsibility of a manufacturer to
constitute an assembly covered by the definition given in Article 1.2.1.5,
this assembly must fulfil the requirements of the Directive.

I worked on the construction of a US$4 billion Nickel Refinery in New Caledonia (a French territory)and all our piping and vessels had to be in accordance with the PED.
An absolute nightmare to work with.
We had to fly in NoBos for inspections / audits at a huge cost - pretty sure they wouldn't have done that if it was not required.

I beleive the Engineering Community is being slightly ripped off by the NoBo's !!!!
Just my two pence worth!!!

I was working for the owner / client.
We had 1500 welders on the project and every time we wanted to do a welder qualification test we had to have a NoBo attend.
We were working to ASME so normally the test would be witnessed by the contractors representative and by myself as the clients rep.
As per PED a NoBo had to attend - we were getting guys who knew nothing about welding but they gave us a nice stamp on the paperwork to go along with their hefty bill,
Cheers,

It adds nothing to material requirements, nothing to joining requirements, and nothing to testing, other than paper and cost.
This is what happens when bureaucrats draft rules rather than the effected parties.

I totally agree with you (see my post). It's a way of the Insurance Companies (i.e. NoBos) to rip off the operating Companies.
