Flexible Metal Hose
Overview
Metal hoses offer various solutions in different applications, from taking up misalignment or thermal expansion to absorbing vibrations. They are also used to facilitate repeating machine movements. SMGI manufactures a wide range of Metal hoses with numerous strengths:
- - No cracking of piping due to stress fatigue
- - No leakages at joints, gaskets, or flanges due to undesirable tensions
- - Simplified mounting and decoupling during maintenance
- - Increased possibilities for prefab manufacturing
Considerations for Selecting a Hose Assembly Solution
Testing
Every SMGI hose assembly is inboard helium leak tested to a maximum leak rate of 1 × 10–5 std cm3/s. For additional testing, please inquire about your requirements!
Cleaning and Packaging
SMGI hose components are cleaned by our standards. Each hose is bagged individually and boxed; longer hoses are coiled, bagged, and boxed.
