Abstract

We analyzed damage to welded joints of pipes made of 12Kh18N10T steel in working media for the production of potassium nitrate. We showed that the corrosion cracking of objects was caused by the action of chlorides in technological solutions under a high level of residual postwelded stresses in welded joints. We give some recommendations for the prevention of the corrosion cracking of welded joints of pipelines and pressure filters.
