Analysis interaction polymer, metal sleeve and metal piping

Peter Sivák, Oskar Ostertag, Vladimí­r Ivančo, Karol Kostolný


The paper deals with some tests of materials intended as filling corrosion damaged pipelines protecting sleeve. The special pressurised protecting sleeve is proposed for use without any need of reducing the pipeline internal pressure. Tests are oriented on detection of interaction between polymeric filling and steel cylindrical pressure vessel during polymer hardening. Some simplified calculation of pressure drop due to volume shrinking of the filling in a test pressure vessel and in a protecting sleeve are presented.
