Seamless steel tubes for oil- and water-hydraulic systems - Calculation rules for pipes and elbows for dynamic loads
Nahtlose Stahlrohre für öl- und wasserhydraulische Anlagen - Berechnungsgrundlage für Rohre und Rohrbögen bei schwellender Beanspruchung
Overview
This standard contains the calculation rules for seamless tubes and elbows made from carbon and stainless steel for oil- and water-hydraulic systems. It is applicable for pipelines which meet the any of the three following conditions: 1. For installation in machines according to Machinery Directive 2006/42/EC. 2. For operation a. with fluids of group 2 in accordance with the Pressure Equipment Directive 97/23/EC (PED) at DN ≤ 200 at any pressure and at DN > 200 and at a maximum permissible pressure PS ≤ 50 MPa (500 bar) or b) with gases of group 2 according to the PED at DN ≤ 100 or PS × DN ≤ 350 MPa (3 500 bar). 3. For operation at a maximum permissible temperature TS of up to 120 °C. It is not applicable for pipelines which fall under the scope of the Pressure Equipment Directive. This standard has become necessary in order to create a clearer delimitation of the content to EN 13480-3. With the publication of DIN EN 13480-3, the previous editions of DIN 2413-1 and DIN 2413-2 have been withdrawn. Practical application of DIN EN 13480-3 demonstrated that this standard may result in wall thicknesses which, according to many years of experience, are too great for hydraulic systems. Specification of another calculation method has therefore become necessary. This standard has been prepared in collaboration between NA 082-00-07 AA "Rohrverschraubungen" ("Tube connections") and the VDEh (German Iron and Steel Institute) on the basis of the withdrawn DIN 2413.
