| Resumo: | The state of Rio Grande do Norte was one of the pioneers and recordists in
the production of oil and gas in onshore fields. However, in recent years production
in these fields has had significant reductions and one of the main causes has been
the maturity of their producing wells. One of the technologies applied in the recovery
of mature wells has been the secondary recovery through the injection of saturated
or superheated steam through the pipes of these wells. However, in the project of a
pipeline subject to temperature variations, there are situations in which the stresses
due to thermal expansions may not have been anticipated. In this case the
designers have an additional task of making a flexibility analysis of the pipes.
Therefore, the objective of this work was to analyze stresses developed in industrial
piping through the use of two numerical simulation software, CAESAR II and
ANSYS, the latter being a finite element program. The results obtained in both
programs were analyzed and compared, showing a similar behavior for the stress
field due to thermal expansion. |
