<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml"><p>The paper deals with corrosion degradation of gas pipeline.
Pipelines play very important role as means transporting
gas media over long distances from producers to end-users.
Gas pipelines present a risk of potential corrosion degradation
that can result in their failure. Corrosion on internal surfaces
of steel pipes takes place in CO2, H2S, H2O and chloride environment.
Degradation of steel results in loss of mechanical
properties, reduction in thickness and ultimate perforation and
failure. Corrosion is the electrochemical process that involves
the fl ow of electrical currents on a micro or macro scale. For
corroding steel, the anodic and the cathodic reactions produces
the electrochemical cell. Corrosion protection of internal
pipeline surface is based mainly on chemical composition of
gas and the use of inhibitors. Corrosion protection of the external
steel surface of the product line involves coatings and
cathodic protection.</p></abstract>
