Extreme Operating ConditionsDesign / CalculationMega axial compensators for heat exchangers aremanufactured according to the corresponding standardsand code regulations, in rated sizes DN 15 to 15,000 and withoperating pressures from 0 bar to 200 bar, temperaturesexcursions from -200 to 800 (load alternation 200 to200,000).Mega compensators are designed using specially developedprograms, which will take account of all applicable standardsand code regulation, e.g. EJMA latest edition ASME Section VIII ASME Section IX ASME B31.1 (Power Piping) ASME B31.3 (Process Piping) TEMA latest edition FEAFinite Element Analysis CPSA Caesar Pipe Stress AnalysisExpansion Joints for Heat Exchanger5

Materials of ConstructionBellows MaterialsBellows are manufactured from austenitic stainless steel andnon-standard materials e.g. Ni, Ti, Hastelloy, Inconel, etc.In addition ferritic materials e.g. carbon steel, CrMo are usedfor the end fitting materials.Selection of the bellows material is the single most importantfactor to be considered in the design of an expansion joint.
