Influence of gas hydrates and concentration of corrosive components on the nature and speed of corrosion processes on pipelines
Journal Title: Вісник Тернопільського національного технічного університету - Year 2017, Vol 88, Issue 4
Abstract
According to the results of corrosion-mechanical tests for the first time the regularities of mutual action of mechanical stresses, concentration of chlorides and hydrate formation on the rate and localization of corrosion processes were established. The coefficients of influence of hydration formation for general and local corrosion were calculated, which make up 1,13 and 1,32, respectively, which confirms the hypothesis about the intensification of local corrosion as a result of hydrate formation.
