scope:

The objective of guideline VDI 3842 is to deal with vibrations in pipework systems, and in particular

• to describe vibration phenomena and the associated kinds of excitation

• to describe and explain calculation methods which allow comprehension of loads and which are used for checking the pipework systems

• to describe and explain measuring procedures for analysing pipe vibrations

• to describe methods for evaluating vibrations and vibration-induced stresses

• to specify remedial measures to apply in the event of vibration problems.

As far as strength checks of pipes are concerned, this VDI guideline primarily provides an overview, referencing the relevant codes of practise applicable to the various branches of industry. Our prime objective here is to make it easier to begin working with the special codes of practise.

The air vibrations excited by the vibrating pipes (secondary air-borne sound) are classified under the field of engineering acoustics and will not be dealt with here (cf. VDI 3733).

Our scope of application covers pipework systems in all branches of industrial plant construction:

• Power engineering

• Chemicals, petrochemicals, process engineering

• Shipbuilding

• Buildings technology

• Water supply systems

Process-specific vibration phenomena are found in the individual industries here.
