Filters and Filter Housings Made of Hastelloy

AVN manufactures filters, filter housings and related components made of Hastelloy according to drawings and project-specific requirements.

Hastelloy Piping and Piping Components

AVN manufactures Hastelloy piping and piping components according to drawings and project-specific requirements.

Tailor-Made Solutions for the Highest Technical Requirements

Every project places different demands on materials, manufacturing and documentation. AVN therefore does not produce standardised series products, but develops individual solutions precisely tailored to the intended application. From small precision components to equipment, we support our customers from material procurement through to the completed assembly.

Manufacturing According to Project-Specific Requirements

We manufacture pressure-retaining components in accordance with the project-specific requirements and applicable technical regulations, including:

AD 2000 Code
DIN EN 13445
Pressure Equipment Directive 2014/68/EU (PED)

Depending on the specification, we process materials with the required material approvals and the corresponding VdTÜV material data sheets. We also manufacture components outside the scope of pressure equipment legislation where no corresponding certification is required for their intended use. This ensures that our customers receive exactly the documentation their project requires – economically and according to their specific needs.

Hastelloy Machining and Welding

Machining and welding Hastelloy and other nickel-based alloys require specialized expertise in welding technology and manufacturing. AVN GmbH holds extensive welding WPS – Welding Procedure Specification for various nickel alloys and employs qualified welding specialists. This enables us to manufacture complex welded assemblies safely and reliably, even when the highest quality requirements apply.

Pressure vessel for research on lithium-ion batteries

Pressure vessel for research on lithium-ion batteries

AVN GmbH serves all areas, from research and development to the finished end product for industry. In this case, the University of Wuppertal’s research focused on the fundamentals of thermal runaway in lithium-ion batteries.

Traction batteries, also known as drive or deep-cycle batteries, are rechargeable energy storage devices for electric vehicles and electrical appliances designed for high cycle stability and long service life. In electric vehicles, they typically reach the end of their lifespan with a capacity or performance loss of approximately 20–30%. Although they are then no longer suitable for vehicle use, they can often be reused in less demanding applications. This second-life use extends the lifespan of the batteries, reduces disposal, and conserves resources. Used vehicle batteries can be used as home energy storage systems for photovoltaic installations to efficiently store renewable energy and conserve resources. Reliability and safety are key challenges in this context and must be assessed, among other things, through fire tests.

The objective was to construct a chamber in which lithium-ion batteries could be subjected to controlled electrical overcharging to induce thermal runaway. Lithium-ion batteries pose a risk of thermal runaway when used on a large scale. This can lead to significant cell heating and the release of toxic and flammable gases, which can cause fires or explosions. To better assess the associated health hazards for residents and emergency responders, a special test setup was developed. Within a secure pressure vessel, lithium-ion cells are deliberately subjected to thermal runaway, allowing the resulting gases to be collected, measured, and analyzed in a controlled manner. The aim is to realistically assess the hazard potential of these gases and improve the safety evaluation of battery systems.

Lithium Ionen Batterien, Hochtemperaturlack, Forschung, Nachhaltigkeit
Schutzblech bis 1100°C aus Chromnickelstahl 1.4841, Schwenkarm
Auslegungsdruck PS 40 bar, Auslegungstemperatur TS 260 °C

The result is a pressure vessel designed for a system pressure of 40 bar and a continuous operating temperature of 260°C. The base is a tube made of unalloyed pressure vessel steel P235GH with a wall thickness of 20 mm. Access points are provided on both sides for improved accessibility during test preparation and execution. These access points utilize flanges made of P250GH and blind flanges made of P265GH with a wall thickness of 90 mm, equipped with swivel arms for easier access. Due to the high test pressure of over 57 bar during final acceptance by TÜV (Technical Inspection Association), all connection flanges had to be designed for a nominal pressure of 100 bar. The interior features an additional heat shield made of high-temperature-resistant austenitic chromium-nickel steel 1.4841 to absorb temperature peaks during thermal runaway and prevent them from being directly exposed to the cylinder tube. A mounting plate is inserted inside the heat shield tube to secure the battery and the rest of the test setup.

Further details and test results can be found in the resulting paper, specifically in sections 2.3 and 3.4 on security analysis, at https://www.mdpi.com/2071-1050/16/17/7288.

Summer outing with a focus on industrial culture and community

Summer outing with a focus on industrial culture and community

This year, our joint summer outing was on the agenda—a wonderful opportunity to spend time together, look back on the past year, and gather new impressions.

The day began in a familiar atmosphere in our workshop. Over breakfast together, we reviewed the current year, exchanged ideas about completed projects, new challenges, and many shared experiences. This relaxed gathering was the ideal way to get in the mood for the rest of the day.

The trip then took us to Mannheim, where we took part in a guided tour on the theme of industrial culture in the commercial port area. During the tour, we gained exciting insights into the development of the Port of Mannheim and its significance for the economic development of the region. It became clear what an important role the port has played for trade, industry, and logistics over many decades and continues to play today. In addition to historical background, the focus was also on technical developments, the architecture of the port facilities, and changes in the world of work.

Our trip ended on a high note with dinner together at the revolving restaurant in Mannheim’s telecommunications tower. In a pleasant atmosphere with an impressive view over the city, we brought the day to a close together and took the opportunity to enjoy many good conversations.

Our summer outing showed once again how valuable shared experiences outside of everyday working life are. They strengthen team spirit and provide space for exchange, new impressions, and fresh motivation for the tasks ahead.
