Let’s shape the
future together.

Yes, through our local partners, we are able to seamlessly integrate even specialized components that fall outside our own manufacturing capabilities into your projects. This enables us to offer you customized solutions that are precisely tailored to your specific requirements.

We offer various options for surface treatment and corrosion protection, depending on the project’s requirements. These include coatings, galvanizing, and special protective coatings for use in aggressive environments. These protective measures ensure the vessel’s long service life and operational safety.

We source piping and flanges flexibly, based on customer requirements and delivery schedules. We work with reliable suppliers and ensure that all components meet the required quality standards.

Yes, we manufacture storage tanks and pressure vessels that are certified according to international standards and codes. These include, among others, ASME, EN 13445, and AD 2000. Our products meet the highest safety and quality requirements, both nationally and internationally.

100% German-sourced materials. We source our steel sheets exclusively from renowned German manufacturers such as Dillinger Hütte and Ilsenburger Grobblech. Our consistent focus on sourcing within Germany ensures the highest quality standards, tested materials, and maximum reliability in the supply chain. This is how true “Made in Germany” quality is achieved—from the raw materials to the finished component.

Yes, we offer customized solutions for various industrial applications, particularly for critical sectors of the chemical and energy industries. We take all technical requirements into account and provide comprehensive solutions ranging from design to testing procedures and documentation.

We offer storage tanks and pressure vessels with the following maximum dimensions and weights:

• Pressure vessels: diameters up to 5,000 mm, weights up to 130 metric tons.
• High-pressure vessels: Design and manufacturing up to 400 bar, diameters up to 5 m, lengths up to 100 m, and weights up to 100 t per unit.

We are certified according to international standards to ensure the highest quality and safety:

• DIN ISO 9001 (Quality Management)
• PED 2014/68/EU (Pressure Equipment Directive)
• EN 13445 (Pressure vessel construction)
• AD 2000 (German standard for pressure vessels)
• ASME U1, U2, and S stamps (for pressure vessel construction according to U.S. standards / pressure vessels and piping)
• EN 1090-1/-2 (Construction of load-bearing steel structures)
• DIN EN ISO 3834 (Welding Technology)

Yes, we offer customized material solutions for critical applications, especially in the chemical and energy industries. We select the most suitable material based on your requirements, taking into account factors such as pressure, temperature, corrosion resistance and mechanical properties.

Engineers and planners at WOLF work closely with customers to integrate specific requirements into the design, e.g. when adapting:

• Volume and pressure range.
• Material selection for particularly aggressive or special operating conditions.
• Safety requirements such as additional pressure safety valves or overpressure protection.
• The integration of system components such as sensors or automation technologies is also taken into account in order to deliver customized solutions.

Our QA team carries out a variety of test procedures to ensure the safety and functionality of hydrogen storage tanks:

• Pressure tests: Hydrostatic and pneumatic tests are carried out to ensure that the vessel holds the required pressure.
• Leak tests: Helium leak tests or leak tests with nitrogen are used to ensure that the vessel does not lose any gases.
• Certification tests: Pressure vessels must be certified according to international standards such as ASME and AD-2000, which requires regular certification tests.
