The Corrosion Reason and Solution

1. Electrochemical corrosion:
   The pump flow channel using same metal materail.
   Small wearing parts as an anode made of low-potential metal. Large parts as the cathode made of high-potential metal.

2. Uniform corrosion:
   Using suitable material(including non-metal). Consider sufficient corrosion allowance when designing the pump.

3. Intercrystalline corrosion:
   Annealing treatment for stainless steel materail part. or using ultra-low carbon stainless steel.

4. Pitting corrosion:
   Using Mo steel(usually 2.5%Mo). And Mo content should be increased accordingly while Cl content and temperature rise.

5. Crevice corrosion:
   Using high content of Cr, Mo metal.
   12% Cr steel <17% Cr steel <Austenitic SS< Austenitic 316SS.

6. Stress corrosion:
   High Ni content (Ni> 25%-30%) of austenitic Cr-Ni steel.

7. Erosion corrosion:
   Ferrite Cr steel <austenite-ferritic steel> austenitic steel.

8. Cavitation corrosion:
   Using cavitation resistant material. Such as Hard alloy, Phosphor bronze, Austenitic SS, 12% chrome steel. etc.

How to prevent corrosion problems in slurry pump?

1. Material selection:
   Factory experience. Similar applications in other site. Experiecne of pump manufacturers. Appropriate documents etc.

2. Coating technology:
   Widely used coating Fusion Bonded Epoxy (FBE) and Polytetrafluoroethylene (PTFE). The effectiveness of the coating is dependents on the type of coating, the preparation of the coating, the application of the coating, the type of corrosion involved, and the type of liquid to which the coating is exposed.

Centrifugal Slurry Pump Leak Reason and Solution

The pump works for a long time during the process of running. Which will lead to the leakage due to the corrosion, abnormal process fluctuations and wrong meratial selection etc.

Reason of leakage:
Improper sealing materail selection.
2. The sealing damage because of Empty work, Cavitation or Long time suppress pressure.
3. Lubrication falure lead to the bearing damage and damage the sealing.
4. Sealing damange caused by the working conditions frequent changes or adjustment.

Protection measures:

1, The pump with a reliable seal (such as double-sided seal).
2, DCS add emergency stop pumping facilities.
3, Add the emergency shut-off valve before the pump.
4, Video surveillance.
5, Combustible gas alarm (or smoke Alarm, flame detectors, etc.).
6, Fire facilities at site.
7, Regular inspection or inspection.
