Q. What is Erosion Loss?
Additional metal thickness must be added in specific locations where metal loss is expected, due to stream flow that is of high velocity, or is abrasive for any reason. Erosion loss usually occurs within a definable area, and compensation can be made as follows:
1. Weld overlay of the area with the intent that the overlay is sacrificial.
2. Addition of a welded wear plate, with the intent that the plate is sacrificial.
Note: Use caution with this method in hydrogen service.
3. Internal refractory linings may be used if appropriate.
