Even if the system design selected covers the stationary operating pressures, pressure surges can still lead to component failure. These phenomena primarily affect longer fluid lines, pipelines and supply networks.<\/p>\n<p><strong>Dynamic loads due to unsteady flow processes<\/strong><\/p>\n<p>Pressure surges can occur whenever there is an intentional or interference-related influence on flow processes. Typical examples of this include:<\/p>\n<ul class=\"arrow-gray\">\n<li>Pump failure<\/li>\n<li>Valves being closed<\/li>\n<li>(Delayed) closing of check valves<\/li>\n<li>Pipe ruptures in heat exchangers<\/li>\n<li>Safety valves being opened<\/li>\n<\/ul>\n<p>The level of the pressure peaks that occur depends, for example, on the speed at which a valve is closed and on the compressibility of the system. The faster the change takes place, the greater the inertial forces that occur and hence the pressure peaks. This means that the quick-action valve that may be required from a safety point of view is counterproductive when it comes to pressure surges and needs careful design.<\/p>\n<p><strong>Numerical simulation to counter damage caused by pressure surges<\/strong><\/p>\n<p>A precise prediction of the pressure surge level that occur can only be determined in individual cases with the help of numerical simulations. There are currently a number of tools for this on the market.<\/p>\n<p>Using such a tool and performing a detailed analysis offer the main possibilities:<\/p>\n<ul class=\"arrow-gray\">\n<li>Determination of possible pressure surges and a comparison with the design parameters<\/li>\n<li>Recalculation to analyse faults and damage<\/li>\n<li>Variation calculations with regard to a cost\/benefit calculation as well<\/li>\n<li>Systematic shut down of pumps and the closing of fittings<\/li>\n<li>Closing time optimisation for fittings and valves<\/li>\n<li>Design of wind boilers as damping elements<\/li>\n<\/ul>\n<p>The basis for the requirements of the pressure surge calculation is provided by <a href=\"https:\/\/eur-lex.europa.eu\/legal-content\/DE\/TXT\/?uri=celex:32014L0068\">Directive 2014\/68\/EU<\/a> on the &#8220;Provision of Pressure Equipment&#8221; from May 15, 2014, also known as the &#8220;Pressure Equipment Directive&#8221;. Annex I, Item 2.2. 2.2. &#8220;Design for adequate strength&#8221; deals with the topic here.
