Product catalog summary
Overview: This document provides a detailed analysis of the tension in split loose flanges used in glass lining technologies. The analysis includes specifications, procedures, and performance evaluations of the flanges under various conditions.
Specifications: The document outlines the desired and actual flange thickness for different nominal bore (NB) sizes: NB 25 (8 mm desired, 14 mm actual), NB 40 (8 mm desired, 14 mm actual), NB 50 (9 mm desired, 16 mm actual), NB 80 (12 mm desired, 18 mm actual), and NB 100 (14 mm desired, 20 mm actual).
Failure Mode and Effect Analysis (FMEA): The FMEA revealed that none of the flanges exceeded permissible tension limits, indicating that the flanges are adequately dimensioned with a high safety factor.
Flange Design: The unique Düker snap fit flange is highlighted as an advancement over traditional DIN loose flanges. It allows for easy assembly without tools and ensures a reliable connection.
Leakage Rates: The document reports extremely low leakage rates for flange connections, even under extreme temperature stress, due to the homogenous introduction of flange forces. Leakage rates are provided for various temperatures, demonstrating the flange's ability to maintain tightness.
Performance Data: The document includes detailed leakage rate measurements at different temperatures and time intervals, showcasing the flange's performance under thermal stress.

“Excellent !” Report on the FE tension analysis of split loose anges NB 25, 40, 80, 100 : The FMEA (failure mode and effect analysis) re- GLASS LINING TECHNOLOGIES vealed that none of the anges exceeded the permissible tension limits. The loose anges are, as a consequence, clearly sufciently dimensioned and, GLASS LINING TECHNOLOGIES as a result, have a high potential safety factor. JOBBING FOUNDRY The following split loose anges were subjected to FMEA for adequate dimensioning: DRAINAGE TECHNOLOGY ENGINEERING flange thickness desired flange thickness actual Loose ange connection Düker GmbH & Co.

Snap t, fasten and the job is done ... it couldn’t be easier! Calcu Calculated, tested, tried and proven! The unique Düker snap t ange is a further development based on the well Even under extreme temperature stress the Düker ange connections have known DIN loose anges. The two halves are simply clipped together without leakage rate of ange connections for glass unbeatable low leakage rates ( between 10 –5 and 10–6 mbar l/s ). This is tools and can be mounted with every other conventional ange to provide a lined pipeline parts due to the homogenous introduction of the ange forces. The proven...
