Page 10: Potential Service Issues
6. Potential Service Issues 6.1 Tube failures The majority of problems facing a cooler are those of corrosion or erosion on the water side. Common types of failure are: a) Impingement attack (or erosion corrosion) This is caused by water containing air bubbles flowing at high speed through the tubes. The impingement of rapidly moving water may lead to a breakdown of the protective copper oxide film built up by the tube thus allowing corrosion/erosion. -
