In the biopharmaceutical industry, rough is a common engineering phenomenon. It is a kind of orange, red or black corrosive granular dirt that adheres tightly to the surface of stainless steel pipes. mainly composed of metal compounds such as iron oxide and nickel chromium. It often occurs at positions such as spray balls, tank walls, pump cavities, welds, and diaphragms, etc.

Particle contamination is a crucial risk control point in the pharmaceutical production process. In the storage and distribution system of pharmaceutical water, as long as stainless steel material is used, rough inevitably occurs. Free rough particles can affect the quality and clarity of the entire pharmaceutical water system; Increase the effective working load of the filter; Block the filter element, etc. The risks of rough to the pharmaceutical industry are mainly reflected in four aspects: quality risk, engineering risk, regulatory risk, and investment risk. Regularly monitor the breeding status and extent of rough in the process system, so as to avoid irreversible quality defects in the finished product and cause significant losses.
