Quality and documentation

Energy equipment parts are usually supplied with a material certificate to EN 10204 3.1, or 3.2 where specified, and a dimensional report. Forgings are tested by ultrasonic testing (UT) to EN 10228-3 and castings by magnetic particle, penetrant or radiographic testing according to the specification. Pressure-retaining castings are pressure tested. More on the quality page.

Frequently asked questions

Can you supply forged rings and flanges?

Yes. Rings and flanges are forged by ring rolling or open-die forging in steels such as C45, 42CrMo4 and 34CrNiMo6, heat treated and machined to drawing.

Do you supply pressure-tested castings?

Yes. Valve and pump bodies can be pressure or leak tested to the test pressure and medium specified on your drawing, and the results are documented.

Is there a size limit for large rings and shafts?

There is no fixed size or weight limit. Send us your drawing and we will define the right production route and confirm feasibility.

Send your drawing. You get a quotation in 3 to 5 working days.

Your drawings are handled confidentially; NDA on request.
