Quality Assurance at Holzner Druckbehälter

Quality from the Start

Quality doesn’t just emerge at the end – it accompanies every project from design through manufacturing to delivery. Our quality assurance is an integral part of our processes and ensures traceable results.

Testing Methods and Documentation

We work according to recognized standards and document the relevant manufacturing and testing steps in a structured manner. This ensures that pressure vessels and systems comply with applicable regulations – including test-ready documentation for inspections.

Non-Destructive Testing

For testing materials and welds, we use the following methods depending on requirements:

  • Visual Testing (VT)
  • Dye Penetrant Testing (PT)
  • Radiographic Testing (RT)
  • Positive Material Identification (PMI)

This ensures leak-tightness, strength and operational safety – even under demanding conditions.

Material and Surface Control

Material certificates, delta ferrite measurements and surface inspections are an integral part of our quality control. All results are documented in a transparent and traceable manner.

Safety for Regulated Industries

Particularly in medical/pharmaceutical, chemical, and energy and process engineering sectors, standards-compliant quality and clean documentation are critical. Our quality assurance provides transparency, safety and planning certainty.

Rely on Tested Quality

We develop the right solution – technically sound and standards-compliant.
