In Germany many companies have had very good experiences after implementing VDI Therefore in Germany as VDI is required according to the TA Luft regulation, users are required to calculate via EN and show that the maximum tightness level is reached. The early attempts in the USA and Germany. This guideline deals with the assessment of technical density of flange connections for fluid and 2920 media for emission control requirements refering to the Technical Instructions on Air Quality Control TA Luft.

VDI-Standard: VDI 2290

The required leak tightness classes for the design of a technically vdii flange connection as required by TA Luft are defined. In addition to the tightness calculations, VDI also demands trained fitters to install gaskets according to EN — therefore correctly calculated torque values for each different flange connection are mandatory — and a quality management system to track everything is required.

Furthermore the guideline gives explanations for the selection of sealing constants as well as additional informations for the calculation of flange connections. The red arrows show that the L0,01 class is reached at roughly 22 MPa. Reduced down time at shut downs due to significantly reduced leakages during the re-start of the process units. Additionally installation errors caused by many fitters not having proper training levels, not using the right tools e.

This lead to many calculations not being right for their systems. EN gasket values are to be provided by the gasket manufacturers, they are often published www. Principle of minimisation In addition, the tightness class L0,01 is just the minimum requirement and the VDI actually attempts to reduce fugitive emissions as much as possible. We believe that high quality products can only be manufactured with highest care taken during whole process of production.

The maximum bolt force is normally given by the stress limits of the flanges and bolts as gaskets can normally withstand relatively high stresses. Only trained fitters are allowed to install gaskets. Together, they form the key global source of technical knowledge and guidance on sealing technology, which is the basis for these articles. Instead they are replaced by EN The following additional advantages have been seen: Typically these sealings secure tightness of various types Pressure Vessels: The guideline does not apply to boltless pipe and flange connections and so called consolidated flange joints without seal or with liquid seals.

Data protection Imprint Deutsch. With this approach tightness levels can be significantly lower than class L0, This calculation code requires gasket material test data according to EN Emission control – Sealing constants for flange connections Order from Beuth Verlag. One of the consequences of this lower tightness class requirement is that some traditionally approved combinations of flanges, bolts and gaskets are no longer sufficient; and will have to be replaced.

It states that the gasket stress during assembly should be as high as possible. The new codes now reduce calculation errors via the newer calculation codes and reduce installation errors by requiring correct training and making gasket data more available.

Publications A method for calculating the design of flanges – Part 1. Higher safety and efficiency of processing units So, why not implement these systems outside of Germany? Components of the guideline are normative references that are necessary for the application of this guideline and the basis for design and calculation of flanged connections and instructions for assembling.

Abstract This guideline deals with the assessment of technical density of flange connections for fluid and gaseous media for emission control requirements refering to the Technical Instructions on Air Quality Control TA Luft. Reduced overall costs due to less leakage in service.

VDI – Resulting consequences for users and manufacturers of static gaskets | Spetech

A correct installation is a must as a flange connection with expensive high quality components is only as good as the quality of the installation. High quality assembly Minimum leakages, maximum safety and highest performance of processing units vdl only be reached by a high quality assembly.

New Standards for Calculation and Testing. This reduces the leakage times meaning less lost products, low emissions etc.

The guideline is valid for metal flanges, e. We use cookies on this website to improve your user experience.
