Due to their superior mechanical characteristics, valve ball and seat made of zirconia structural ceramic materials are more stable during the operation of sucker rod pumps and are adaptable to a wider variety of application environments. Valve ball and seat prepared using zirconia ceramic materials can perform much better.
Advantages of Zirconia Ceramic Valve Ball and Seat
The valve ball and seat made of advanced zirconia ceramic materials offer numerous advantages, such as corrosion resistance, wear resistance, erosion resistance, high strength, and high rigidity, etc., therefore possessing 10 times the service life of stainless steel valve ball and seat. Additionally, the valve cover is made of stainless steel, which enhances the anti-corrosion performance. High strength can guarantee that the performance of sucker rod pump won't be affected when being transported or constructed. Because zirconia ceramic materials are neutral, they have no affinity with wax or scale, so scaling and waxing won't occur. Moreover, zirconia ceramic materials are not corroded in the presence of H2S, CO2, and Cr, and their self-lubricating properties prevent the valve from being blocked by particles between the sealing surfaces.
When compared to metal valve ball and seat, zirconia ceramic valve ball and seat have a higher hardness, meaning they can withstand more wear and have longer service life. Second, zirconia ceramics have a lower coefficient of friction than metals, allowing them to operate more smoothly with less friction. Third, zirconia ceramics are chemically resistant and can survive harsh oil and gas fluids without corrosion. Finally, zirconia ceramics are less likely to crack or deform in the high-temperature conditions of oil wells because they have a lower coefficient of thermal expansion than metals.
Specification of Zirconia Ceramic Valve Ball and Seat
Features of the Ceramic Zirconia valve ball and seat
Composition and Structure
Usually composed of partly stabilized zirconia (PSZ), which under stress changes phase from tetragonal to monoclinic structure, zirconia ceramic valve balls and seats are more robust and resistant to fracture propagation. Because of its phase change toughening process, zirconia ceramics are ideal for demanding uses in pumps and valves.
Mechanical Properties
Excellent mechanical qualities are one of the main benefits of zirconia ceramic valve balls and seats:
Resistance to Wear and High Hardness
High hardness and outstanding wear resistance of zirconia ceramics make them perfect for uses where components are worn and eroded by abrasive materials.
Fracture Toughness
Zirconia ceramics' phase change toughening process increases their fracture toughness, enabling them to resist stress-related catastrophic failure and to survive mechanical shocks.
Chemistry and Thermal Stability
Excellent thermal stability and high temperature tolerance without any performance loss characterize zirconia ceramic valve balls and seats. Their outstanding chemical resistance also qualifies them for usage in corrosive settings where exposure to acids, alkalis, and harsh chemicals is a worry.
Uses
Application areas for zirconia ceramic valve balls and seats include:
Natural Gas
In offshore drilling, refining, and petrochemical processing, where corrosion resistance and dependability are essential, used in valves and pumps.
Process Chemicals
Used when chemical stability and corrosion resistance are critical in chemical valves and pumps handling strong chemicals and solvents.
Development of Power
In nuclear power plants, steam and gas turbines, and valves and control systems working at high temperatures and pressures.
Pharmaceutical and Medical
Applied in fluid handling equipment and sanitary valves where hygienic conditions, dependability, and resistance to sterilizing procedures are needed.
