Oil and Gas Industries

Oil and Gas Industries


Wear-resistant ceramics like alumina, zirconia, and silicon nitride can be used in oil and gas drilling equipment. Their typical applications include nozzle, valve seat, liners, piston pump components, seals, and drilling components. They can vibrate in high-pressure environments, as well as oil and mud mortar. They occasionally work in the presence of acid and salt, where the requirements for wear and corrosion resistance are more stringent.
 
Ceramic Lining
 
  • Excellent anti-corrosion performance;

Alumina ceramic lining has exceedingly high chemical stability. It can resist corrosion of various acids and alkalis, with anti-corrosion performance that is several times, or even dozens of times that of stainless steel.

  • Outstanding wear resistance;

The hardness of the ceramic lining is more than five times that of ordinary oil pipes, making it more wear-resistant.

  • Good anti-wax and scaling properties;

Plenty of scaling will stick to the oil pipes and oil pumps throughout the production process of the oil well, which has become a serious impediment to oil field production. The wax and scale in the oil and gas do not electrochemically react with the neutral ceramic lining. The wettability of the surface (hydrophilic and oil-repellent) is enhanced by the dense and smooth ceramic surface, and there is no generation of scale and wax nuclei, thus they cannot take root and build up on the ceramic surface.

  • Exceptional mechanical characteristics;

The mechanical properties of the matrix of the ceramic-lined composite oil pipe remain unchanged, and the ceramics possess exceptional crush strength.


Ceramic Seal Components

For sealing components, there are many different ceramic materials to choose from, including silicon carbide, silicon nitride, alumina, zirconia, etc. These materials are primarily used for sealing under demanding working conditions, such as high temperatures and severe corrosion, where conventional metal seals cannot use. As an insulating and airtight material, ceramic sealing components can help equipment maintain airtightness in challenging working situations, eliminate worries about aging and deterioration, and improve the equipment's applicability and dependability. The following are the properties of ceramic seal components:

- Acid and alkali corrosion resistance;

- High wear resistance;

- High compressive strength;

- High thermal expansion coefficient;

- High-temperature resistance.

The sealing material used is determined by the material being transported, the chemical reactivity, temperature, and pressure.


Ceramic Valves and Valve Components

Metal valves can no longer withstand the demands of harsh working conditions like high wear, strong corrosion, high temperature, and high pressure in harsh environments of the chemical industry, coal, and petroleum. This is mostly demonstrated by the leak-prone nature of metal valves and the sealing surface's susceptibility to corrosion. Industrial-grade ceramic materials like zirconia and silicon nitride deform extremely little and offer much higher mechanical strength than metals. Their tensile strength, compressive strength, elastic modulus, and hardness are extremely high, which can significantly improve the fluency and tightness of the pipe system, thereby increasing the stability and safety of the supporting equipment's operating system. Accessories for ceramic valves include check valves, gate valves, valve balls and seats, and valve plates.


Ceramic Bearing Balls

In the field of offshore operations, there are numerous corrosive environments including atmospheric corrosion, H2S stress corrosion, and chloride ion corrosion, all of which have characteristics of multiple states, changeable and uncertain corrosion environments, putting forward higher requirements of corrosion resistance for bearing balls. Metal bearing balls are vulnerable to corrosion, which can lead to damage and decreased lifespan. Ceramics, like silicon nitride, are very resistant to conditions that are acidic and alkaline, with the exception of a small amount of acids like hydrofluoric acid. Their average lifespan is 4 to 25 times longer than that of stainless steel bearings.


Frac Plug

As oil wells become deeper and branch wells get longer, it is especially urgent to find a quicker and more dependable frac button solution for isolation. The zirconia ceramic frac plug offers high hardness, high strength, low density, good fracture toughness, and is resistant to corrosion, making it tough enough to withstand high-pressure fracturing and simple to mill out. As a result, effective fracturing isolation is achieved, and the amount of debris removed from the well after a fracturing operation is significantly reduced. Based on customer drawings and sizes, zirconia frac buttons can be customized with high dimensional accuracy and stable output.
