Suitability matrix: which component can be made with which process – technically and normatively?

Ten component classes of piping against five metal processes of additive manufacturing. Every cell carries two traffic lights: is it technically possible? Is it normatively permitted – as a standard part, as a pressure equipment part? Plus the reason and our recommendation. Choose a process or show pressure-retaining parts only.

Suitability matrix: which part, which process – technically and by the rules

Tap or click a cell: the reason, our recommendation and the order of magnitude of the cost appear below the matrix.

Traffic lights are our assessment from the process characteristics and the rules – the binding assessment for a pressure part lies with the notified body and the manufacturer. No prices, no delivery promise.

How to read the matrix

The upper traffic light of each cell is the technical one: green possible, yellow possible with restrictions, red not worthwhile. The lower one is the normative: green means permitted or no standard part needed, yellow only with a particular material appraisal or manufacturer qualification, red no standard part and no approval. The reason and our recommendation appear when a cell is selected. The traffic lights are our assessment from the process characteristics and the rules; the binding assessment of a pressure-retaining part lies with the notified body and the manufacturer.

Frequently asked questions on the suitability matrix

Why two traffic lights?

Because the answers diverge: a flange is technically printable and still not a flange normatively; an impeller is normatively free and technically the showcase. Whoever shows only one traffic light conceals half the picture.

What does “only with a particular material appraisal” mean?

That the material of the pressure-retaining part must be assessed under Annex I No. 4 of the Pressure Equipment Directive by way of a particular material appraisal by a notified body – per part, per manufacturer.

Where do the assessments come from?

From the process characteristics to ISO/ASTM 52900, the product standards, the Pressure Equipment Directive and the freely accessible scopes of the rules; the manufacturer statement by KSB proves that certified production exists. The sources are given on the technical pages.
