Quality Assurance

In order to ensure that our customers' strict quality requirements are met, our products go through numerous test and inspection steps.
The basis of our quality assurance approach can be found in our certifications as per the following standards and directives:

  • AD-2000 HP0
  • Pressure Equipment Directive
  • ISO 3834-3
hp-0 and iso 3834-3 en ped modul a1

We can also fabricate vessels in accordance with ASME (without a U stamp).

We perform the following tests and inspections in line with all relevant standards and customer specifications:


  • Checks designed to make sure that the correct material has been used
  • Visual inspections
  • Dye penetrant inspections
  • Radiographic testing
  • Ultrasonic testing
  • Surface roughness testing
  • Pressure tests
  • Leak detection

These tests and inspections are performed exclusively by certified staff.

Every single one of our welders has completed their apprenticeship with us and can fall back on years of experience (all corresponding welding procedure and welder qualification certificates are available, of course). All work is performed under the supervision of our production manager, who has many years of experience as a welding expert.
Moreover, a welding engineer is in charge of preparing all required welding and testing and inspection plans.

Finally, we schedule regular visits from external inspectors, who have consistently provided us with positive feedback regarding the quality of the work we do.
