... or condenser tubing, it is usually confined to a short distance on the inlet end of the tube where the fluid flow is turbulent. Impingement attack can be controlled by use of corrosion-resistant alloys, such as copper alloy C71500 (copper nickel, 30%). Impingement attack also has been somewhat relieved...

..., low-temperature steam piping, and condenser and other heat-exchanger tubes that are subjected to direct impingement by wet steam. Liquid impingement erosion in tubing and piping is most likely when fluid velocities exceed 2.1 m/s (7 ft/s). Damage occurs first at locations where direction of flow...
