Abstract

L'invention concerne un procédé d'inhibition de la corrosion d'un pipeline d'acier et de la formation d'hydrates de gaz dans celui-ci, lors du transport, à travers ce pipeline, d'eau et de gaz, ou d'eau et d'une huile, ou de mélanges de ces substances, ce procédé consistant à introduire un copolymère de caprolactame de vinyle et de vinylpyridine dans ce pipeline.
