Popis: | In high-temperature reactors fabricated from alloy steels with an austenitic facing, contact pressure develops when the wall of the cylindrical shell is heated above 200°C in the zone where the built-up layer abuts the base metal due to the difference in their coefficients of linear expansion. A procedure is proposed for analysis of the contact pressure and evaluation of the cyclic strength of the housing and facing with consideration of the internal pressure and pressure within the zone of contact. As an example, results are presented for an R-201 reactor in a plant used for hydrotreating fuels. Calculations indicated that the allowable number of cycles for the facing is an order lower than that for the housing of the reactor. |
