Cobalt Alloy 20 Ball Valve
Cobalt Alloy 20 Ball Valve Description
Material selection and processing
We use high-performance Stellite 20 material for processing by casting or powder metallurgy.
The casting method requires the size and precision requirements of the Stellite ball, making the corresponding mold, and then high-temperature melting and casting. Powder metallurgy is made by the process of powder mixing-pressing-high-temperature sintering.
In order to improve the size accuracy of the ball, it must be ground and polished, and there is strict quality control. You can order our products with confidence.
Advantages
- Excellent wear resistance: can effectively reduce the wear of the ball and valve seat, maintain the normal function and sealing performance of the valve.
- Excellent corrosion resistance: has excellent tolerance to various acids, alkalis, salts, and seawater.
- High mechanical strength and fatigue resistance: It can withstand strong pressure and continuous impact without deformation and fragmentation
- Excellent sealing performance: can effectively prevent medium leakage under harsh working conditions such as high temperature, high pressure, and strong corrosion.
- Low thermal expansion and good thermal conductivity: good dimensional stability at high temperatures and low maintenance cost
Application
Cobalt Alloy 20 Ball Valves can be widely used in pipeline transportation and valve systems in industrial fields such as oil and gas, chemical processing, papermaking, nuclear power, steel production, seawater desalination, and shipbuilding. It can play a good sealing role and convey medium to ensure the normal operation and service life of the pipeline system.
FANMETAL can also provide customers with high-quality Cobalt Alloy 20 Rod, Cobalt Based Alloy Welding Rod, Valve Parts, Cobalt Alloy Metal Sleeve Bushing, Cobalt Chrome Alloy Fiber Cutters, and other cobalt-based alloy products.
