Meet tightness and strength criteria with MDESIGN

Flange connections according to DIN EN 1591

The safe sealing of machines and systems is a particular challenge for engineers. When it comes to the unwanted escape of liquids or gases from machines, the calculations and verifications are of crucial importance.

A flange-gasket-bolt system must be designed to be technically safe and as economical as possible. In addition, the requirements for the flange connection must be met under all operating conditions. The safety requirements are specified in the European Pressure Equipment Directive (PED) 2014/68/EU.

Secure and time-saving calculation

MDESIGN is used to design the flange connection in the main force connection, taking into account the PED and the tightness and strength criteria in accordance with EN 1591-1. The entire flange-gasket-bolt connection system is considered with the aim of both ensuring the strength of the design and providing proof of tightness.

In addition to the user-defined flange geometries, standardized designs in accordance with EN 1092-1 are selected from the MDESIGN database with all the necessary data.



The MDESIGN 3D wizard makes it easy to assemble the assembly before the calculation. This allows you to visually select the flange pair, gasket, bolts and the material or strength class. Then just enter a few load data parameters.

Visualization and direct data exchange

All necessary results and information are clearly presented in the familiar MDESIGN comparison of the boundary conditions.

Project and task-specific changes are immediately converted into new results. The generated 3D models can be used directly in CAD systems via the Step interface.



In addition, MDESIGN creates a STEP interface to a CAD system, so no double data entry is necessary.

Simplify your technical documentation

MDESIGN prepares the documentation for the verifications with calculation tasks, results, supporting graphics, specific comments and standard references automatically and without wasting time.

Individually configured or adapted to the CI, MDESIGN documents in PDF/A or HTML format can be integrated into the company's existing processes.

International projects also benefit from automatic documentation in English.
