In order to reduce the risk of red rust in the GMP WFI system for sale, this factor should be fully considered during manufacture, and this phenomenon should be avoided through good design. The following precautions are recommended:
1. For the GMP WFI system, on the basis of satisfying the process conditions, appropriately reduce the circulating temperature of the water for injection system, such as maintaining the temperature between 70 and 80 degrees Celsius.

2. Select high quality raw materials for the installation of GMP WFI system for sale, and systematically trace the material reports of stainless steel pipes, pipe fittings and valves to ensure the quality of materials and the roughness of polishing.
3. When welding, weld the GMP WFI system for sale in strict accordance with the standard operating procedures. After the welding is completed, the piping system should be pickled and passivated as soon as possible to form a passivation protective film.
4. In addition to the initial pickling passivation after the installation of the GMP WFI system for sale, periodic maintenance and passivation of the system is also required to effectively form a passivation film with good pickling passivation.
5. Strictly control the scope requirements of the dead angle of the GMP WFI system to avoid residues and effectively prevent crystal corrosion from the source.
6. Since nitrogen sealing will accelerate the red rust phenomenon, except for special products such as amino acid products, try not to carry out nitrogen sealing treatment on the storage and distribution system of the GMP WFI system for sale.
