Resumo: | |||||||||||||||||||||||||||||||||||||||||
An experimental study on reduced scale models of the PE-3
pipeline, built in Guanabara Bay in 2003, is described in
this work. The main characteristic of the PE-3 pipeline is
the zig-zag geometry. This pipeline has an external
diameter of 18 and is used to transport heavy heated oil
from the Duque de Caxias refinary to a shipping terminal.
The present study was carried out in reduced
models with physic similitude, and the objective is
to evaluate experimentally the behavior of the
model, varying the zig-zag angle and the length of
the pipeline. The models were submitted to
temperature variation, internal pressure and different
conditions of lateral and longitudinal support,
simulating the real working conditions of the prototype.
For each length (12m, 16m and 18m) and zig-zag angle (5°,
10° and 15°) tests were carried out with the model
without lateral reaction of the soil, with lateral
reaction simulating 1 meter of buried prototype,
with lateral reaction simulating 1 meter of buried
prototype and central free span, and with
horizontal imperfection. Two straight pipeline tests were
carried out in order to compare with the zig-zag model.
The results showed that the zig-zag geometry
minimizes the effects caused by the thermal expansion of
the pipeline.
