Pressure equipment
You build pressure equipment
Vessels and piping where the risk category decides who is allowed to approve the work — and the technical file has to prove it did.
Runs on Fabrication suite, underPED 2014/68/EU, ASME BPVC Section IX, UNI EN ISO 3834.
What it costs you today
Where the record breaks.
The risk category moves under you
A vessel is quoted and planned as one category, then a design change pushes it higher — and that retroactively changes who was allowed to approve the welders and the joining procedures.
Cost Approvals that were valid become insufficient, discovered late and re-run under schedule pressure
Approved on the day, or not at all
For category II and above the procedures and welders must carry a notified-body or RTPO approval that was live on the date of the work. A certificate that lapsed the week before is the same as no certificate.
Cost A conformity gap that surfaces at final assessment, when it is most expensive to close
The technical file is assembled by hand
Category basis, conformity module, approved procedures with their approving body, welders valid on the date, NDT by the right route, material documents — chased across folders in the last weeks before the CE mark.
Cost Engineering time on every unit, and a file that is only as complete as the last person to touch it
Who this is
You build pressure equipment — vessels, piping, assemblies above 0.5 bar — under the Pressure Equipment Directive 2014/68/EU. Some of it ships to Europe with a CE mark; some of it exports under ASME.
Either way the work itself is welding, NDT and inspection. The regime is a layer laid over it that decides how independently the work must be proven.
The regime you actually live under
PED places each item in a risk category, I to IV, from the fluid group and the pressure and volume or diameter.
The category is not a label — it selects the conformity assessment module and how deeply a notified body is involved. Two Annex I requirements dominate the shop:
Permanent joining procedures must be approved. For category II and above the welding procedure approval is issued by a notified body or a recognised third-party organisation — not by you.
The welders and operators making those joins must be approved by the same route. An employer-issued certificate is not enough for those categories.
And for category III and IV, the NDT personnel examining permanent joints must be approved by a recognised third-party organisation. Self-certified does not satisfy the directive.
For export you carry the parallel ASME IX qualification of procedures and performance, and ISO 3834 sits underneath as the quality requirements for the welding itself. Worgify treats all three as switchable per job, not as separate products.
The specific pain of proving it
The recurring trap in this market is category creep. Because the category decides who was allowed to approve the procedures and the welders, a design change that raises the category can invalidate approvals that were correct the day before.
Catching that at final assessment is where margin disappears.
Worgify computes qualified ranges from the essential variables rather than restating a PDF.
So “does this procedure, this welder, this route cover this joint, in this category, on this date” is answered by the system. The approving body and approval reference travel with the record.
The technical file is assembled as the work happens:
- the category basis;
- the module;
- the approved procedures and personnel valid on the date;
- the NDT by the required route;
- the material inspection documents to EN 10204.
All of it lands in the same dossier instead of being reconciled at the end.
