Quality assurance

Quality assurance is a priority at BOLZ INTEC

Our QM system guarantees traceability & reproducibility

In hygiene-sensitive sectors such as the pharmaceutical and cosmetics industries, products and processes must meet the strictest standards to prevent contamination. BOLZ INTEC's quality assurance ensures that all GMP and EHEDG requirements are met. 

In this way, we guarantee that all of the containers we produce are of consistently high quality, which enables consistent performance and safety for the end products. In addition, our QM system ensures that the origin of each container and the associated materials as well as the entire production process can be traced. Potential problems can be identified, rectified and avoided in the future. This is crucial for compliance with strict regulations and certification, as well as for ensuring quality and safety.

Quality assurance at BOLZ INTEC

The range of our test methods

Documentation 2.1 and 3.1 according to DIN EN 10204

These standards specify requirements for the documentation of material tests in order to confirm the quality and conformity of the stainless steel surfaces supplied.

Radiographic testing (RT)

This method uses X-rays to detect any internal defects or irregularities in the stainless steel surfaces.

Dye penetrant testing (PT)

It enables the detection of surface cracks and porosities in stainless steel surfaces through the penetration of a fluorescent liquid.

Pressure test (LT)

This test checks the tightness of weld seams and surfaces by applying a certain amount of pressure.

Spectral analysis (XRF) for incoming and outgoing goods inspection (PMi)

This method analyzes the chemical composition of the stainless steel surfaces to ensure that they meet the specified requirements.

Ultrasonic wall thickness measurements (UT)

They are used to measure the thickness of stainless steel surfaces to ensure that they meet the required specifications.

Visual Inspection (VT)

This visual inspection detects visible surface defects such as cracks, scratches or unevenness.

Ferrite testing with a Fischer ferrite scope

This method determines the ferrite content in the stainless steel surfaces in order to evaluate their mechanical properties.

Surface roughness measurement, perthometer (µ)

This test measures the roughness of the stainless steel surfaces, which is important for the application and appearance.

Passive layer measurement KorroPad

It measures the thickness of the passive layer on the stainless steel surfaces, which is used to assess their corrosion resistance.

Digital X-ray system for weld seam inspection (Rö)

This method checks the quality of weld seams in stainless steel surfaces by using X-rays.

The quality of BOLZ INTEC comes with a letter and seal of approval

Frequently asked questions to BOLZ INTEC

You ask, we answer

Our stainless steel containers are used in various industries, including pharmaceuticals, chemicals, food, cosmetics, energy and environmental technology, aerospace, as well as research and laboratories.
Our stainless steel containers are available in a variety of sizes and capacities to meet the individual requirements of our customers. Contact us for customized solutions.
We offer customized solutions and adapt our stainless steel containers to individual requirements such as process parameters, volumes and special functions.
Our services include electropolishing, passivation, mechanical processing and the unique Optimized Grind Finishing (OGF) process for optimum surface quality.
Our containers meet the strict hygiene standards of the EHEDG (European Hygienic Engineering & Design Group) and are therefore ideal for the pharmaceutical and food industries.
Our experienced team offers comprehensive advice and support for the seamless integration of our stainless steel containers into existing production processes.
Maintenance is minimal. Regular inspections and cleaning if necessary are sufficient. Our stainless steel tanks are durable and low-maintenance.
Time savings, lower risk of production downtime, reduction of product losses, improved product quality and safety as well as cost savings in cleaning processes.
Our optimized stainless steel containers offer improved cleaning, low adhesion and meet the highest hygiene and cleanliness standards.
Our stainless steel containers are resistant to aggressive chemicals and have been developed for safe storage and transportation in the chemical industry.
The OGF process enables reproducible surface quality, low particle adhesion, visual aesthetics, improved corrosion protection and applicability in critical industries.
The reduction of build-up leads to shorter cleaning and maintenance times, increased reusability of the containers and thus to an overall increase in production efficiency.
The OGF process results in low particle adhesion, improves cleaning efficiency and reduces the risk of contamination of product batches.
The improved cleanability and the subsequent electropolishing process help to extend the service life of the stainless steel containers.
Our containers meet industry-specific standards and certifications, including EHEDG for hygienic standards in the food industry.
Thanks to their durability, our optimized stainless steel containers help to reduce waste and resource consumption. The efficient cleaning behavior also improves the environmental balance.
