Proven leak tightness
Leakage values of our JACOB tubing systems in detail
The requirements for leak tightness in industrial piping systems are continuously increasing — driven by the need for greater energy efficiency, technical safety, and process reliability. In response, our JACOB pipe systems have undergone extensive leak testing under realistic operating conditions. The goal was to document their exceptionally low leakage rates in accordance with the relevant standards for lipped ends and flanged pipe constructions..
The test results confirm that our system clearly meets the required limit values according to DIN 25496 and DIN EN 1751.
If you have any questions about a specific standard that is not listed, please contact our technical department – we will compare your requirements with the measured values.
Leakage values – flared tube construction (clamping ring system)
Our clamping ring system with flanged sealing rings was tested for tightness. The results show that the leakage rates are well below the permissible limits of various standards, even at increased test pressures. We tested up to DN400.
Special features of the test system:
- Seam-welded tube components (no structural leak paths)
- Tightness of the tube bodies: no detectable leakage
- Minor leakage exclusively at connection points within the expected standard range
Leakage values – flanged tube construction
Our flange connections were tested under realistic conditions with several nominal diameters. No measurable leakage was detected in any of the assemblies – even at a test pressure of 500 mbar. The result shows that the flange connections are extremely tight when properly assembled. The measured values are below the detection limit of the measurement technology used. The flange connections were tested up to DN800. The test confirms the tightness in accordance with DIN 25496:2021-10 even for large cross-sections, provided that the assembly is tension-free and carried out in accordance with the installation specifications.
