The software used by Belman is tested and validated through close co-operation with reputable institutions such as DNV and TÜV who also use this software regionally. SAMPLE - EJMA CALCULATION REPORT: Bellow Design Calculation - EJMA 7 19: Calculation /2003/551: Revision: 0 : Supplied by: NN. The results of the analysis are often used internally for optimisation of the Expansion Joint construction, but as an additional service Belman can prepare an evaluation report as part of the technical documentation package. Fluidyne Bellows, Chennai, India, Expansion joint, Bellows, EJMA, Metal bellows, Nesting ripple type welded diaphragm bellows, Diaphragm bellows. In such situations, Belman can verify the integrity of the expansion joint construction by means of complex Finite Element Analyses.įor this purpose, we use ANSYS® and the validation is carried out according to the terms of the specified design standard. For example, the geometrical complexity of the expansion joint construction or the need for a further optimisation of the design could mean that the analytical formulas cannot be applied. In certain situations, it is not immediately possible to validate the pressurised integrity of an expansion joint construction by means of the analytical formulas specified in the applied design standards. In this work A finite element analysis (FEA) of bellows proposed in this paper to for the validation of the software results and EJMA design calculated results.
