A metal hose connects plant components that move relative to each other or are not exactly aligned. It absorbs vibration from engines and pumps. It compensates for misalignment during installation and withstands high temperatures. Typical applications are combined heat and power plants, standby generators, steam and thermal oil lines and compressed air.
An expansion joint mainly absorbs the axial expansion of a line. A metal hose is more flexible. It compensates for misalignment and movement in several directions. The braid holds the internal pressure and protects the corrugations. For pure thermal expansion in exhaust lines expansion joints are usually the better choice.
The decisive factors are the bend radius, the movement in operation and the temperature. If a hose is bent too tightly or installed twisted, the corrugations fatigue sooner. As the temperature rises, the permissible pressure falls. That is why we design the hose to your operating data and not just to the nominal size. We also supply matching flanges.

A photo of the old hose with its length and connection dimensions is enough to start.
Yes. Eurolog delivers metal hoses to the installation site throughout Switzerland and abroad, for example to Germany, Italy or France. We arrange transport, customs clearance on import into Switzerland and export documents.
Yes. The details on this page are examples. We also source other sizes, materials and makes, replacements for older plants and special designs to drawing. For a first enquiry a photo, the nameplate or a sketch is enough.
