Hydrogen-carrying tubes and assemblies
The fischer group is a market and technology leader in the manufacture of laser-welded stainless steel tubes. Thanks to our many years of experience in production and quality assurance, we manufacture tubes with a weld seam factor of 1, which makes our products ideally suited for use as hydrogen-carrying tubes.
Green hydrogen in particular will play a key role as a sustainable energy carrier and storage medium. Due to its physical properties, it places high demands on materials and processing — demands that we reliably meet with our technology and expertise.

Highest quality & precision
- On request, we also manufacture our stainless steel tubes as precision tubes with a roundness of 0.009 mm.
- Avoidance of material embrittlement through adapted material selection and special production processes.
- Reliable stability with regard to the system variables of: hydrogen partial pressure, hydrogen purity and mechanical stress.
- Test standards based on EIGA DOC 121, ASME B31.12
- Tensile tests: slow strain rate test in combination with dynamic tests
- Lifetime pressure cycle tests in combination with a hydraulic burst test
- Specification of special material groups
Quality by conviction
The fischer group lives up to extraordinary quality standards in all areas of the company. Internationally recognized quality management systems and certifications are an expression of this fundamental conviction.
Metal hydride storage systems are used wherever hydrogen needs to be stored safely, at low pressure, and in a compact form. For these storage systems, reliable, media‑resistant, and precisely manufactured tubing technology is essential to ensure the safe supply, discharge, and thermal management of hydrogen.
Our fischer pipes are ideally suited for use in metal hydride storage systems, as they reliably meet the high requirements for tightness, material quality, and temperature resistance.
