Abstract

MORATILLA, B.Y.; LINARES, J.I.  and  PORTOLES, A.. Analysis of Mechanical Behavior of Cladding of Stainless Steel over Low Alloyed Steel in Process Reactors. Inf. tecnol. [online]. 2005, vol.16, n.1, pp.69-73. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642005000100010.

A simple study of tensions was carried out on stainless steel and low alloyed steel. The reason for the study was that a typical practice in the petrochemical industry for materials cost reduction is the use of layers of stainless steel cladding over low alloy steel in the construction of reactor walls. The coefficient of thermal dilatation and its' evolution throughout the thickness of the thermally affected zone was determined using a test sample obtained during the construction of a reactor. Later, the results obtained were applied to a model of the reactor wall using the finite element method. The results suggested that the use of the cladding was scientifically and technologically justified.

Keywords : reactor cladding; stainless steel ; low alloy steel; differential stress; finite elements.
