Cemented carbide used for plungers is a powder metallurgically processed material consisting of a ceramic hard phase and a metallic binder (cement). The technical term for these materials is cermet. For hyper compressor plungers, the hard phase is WC, while the binder is Co metal. Some minor other carbides and metallic elements may be added to improve certain properties. The tungsten carbide hard phase provides for wear resistance while the metal binder guarantees toughness. This is the major difference with technical ceramics where there is no metallic binder which makes ceramics too brittle to be used for plungers.
Cemented Carbide Plunger are used in hyper compressors to compress ethylene gas to the reactor pressure. This requires a wear resistant plunger material that combines the necessary mechanical properties and wear resistance for these extreme conditions. The only material that has these properties is cemented carbide.
Why Our Tungsten Carbide Plungers are Ideal for Hyper Compressors
1. Extreme Hardness and Wear Resistance:
- Tungsten carbide is one of the hardest materials available, making it ideal for high-pressure applications where wear is a major concern.
- It maintains its shape and surface finish even after prolonged use.
2. High Compressive Strength:
- Tungsten carbide can withstand the extreme pressures generated in hyper compressors without deforming or failing.
3. Corrosion Resistance:
- Suitable for handling corrosive gases and chemicals commonly processed in hyper compressors.
4. Thermal Stability:
- Carbide plungers can operate efficiently at high temperatures, which are often generated during high-pressure compression.
5. Long Service Life:
- Reduces downtime and maintenance costs, as carbide plungers last significantly longer than traditional materials like steel.
We know some causes of corrosion cannot be prevented because they are inherent to the process.Therefore it was important to develop materials that are more corrosion resistant. The problem however is that these corrosion resistant materials need to have mechanical properties that are suitable for the use in high pressure and high fatigue applications. This is even more so for cemented carbide since it is a brittle material. WC will not be attacked by most of the corrosive products and environments;Co is used as preferable binder because it has the best wetting properties and
it gives the best mechanical properties in the finished part.
Corrosion and thermo-mechanical fatigue cracks, the most frequently occurring plunger defects, were discussed. A special
corrosion resistant plunger material was developed to reduce plunger corrosion while the mechanical properties are superior
to standard materials.
