Ball valves in long-term use, due to frequent opening and closing operations, the chemical nature of the medium and the complexity of the working conditions, there may be a variety of wear and tear, corrosion and aging and other problems. In order to ensure the reliability and performance of ball valves in long-term use, it is necessary to take appropriate maintenance measures and optimize the process design.
What is a ball valve?
A ball valve is a type of valve that controls the opening and closing of a fluid and the regulation of flow by rotating a spool. Its core component is a sphere with a circular through hole, the sphere rotates around the valve stem to realize the opening or closing of the valve. When the through-hole of the sphere is in the same direction as the pipeline, the medium can flow through; when the sphere is rotated 90 degrees so that the through-hole is perpendicular to the pipeline direction, the medium is blocked, thus realizing the closure of the fluid.
Process principle of plasma cladding
Plasma cladding melts the alloy powder or wire material through plasma arc and deposits it on the surface of the base material of the ball valve at high temperature, forming a metallurgical bond with the base metal. This process can generate a dense, uniform coating on the surface of the ball valve, greatly improving the ball valve surface wear resistance, corrosion resistance and high temperature resistance.
Application of plasma cladding in ball valves
Plasma cladding is a highly efficient surface modification technology, through the plasma arc as a heat source, the wear-resistant, corrosion-resistant, high-temperature resistant alloy material cladding on the surface of the ball valve, in order to enhance its performance in harsh working conditions. This technology is widely used in the manufacture of ball valves, especially for petrochemical, natural gas, metallurgy and electric power and other fields of ball valves.
What do you need to know about ball valve surface cladding?
cladding material:
Ball valve cladding materials are often selected wear-resistant, corrosion-resistant and high-temperature resistant metal alloys, such as cobalt-based alloys (such as Staley), nickel-based alloys, chromium-based alloys and so on. These materials can effectively improve the durability of the ball valve in extreme working conditions.
cladding process:
Common cladding methods include laser cladding, plasma cladding, and so on. These processes melt and deposit alloy powder or wire at high temperature onto the surface of the ball valve to form a metallurgical bonding layer with the base metal, thus greatly improving the surface performance.
Application Scenario:
Ball valves are widely used in petrochemical, natural gas, metallurgy, electric power and other fields, especially in high temperature and high pressure, corrosive media strong working conditions, cladding process can extend the service life of the ball valve, reduce maintenance costs.
Advantages of cladding:
Improve wear resistance: In the operating environment of frequent switching of valves, the clad ball valve can withstand long-term friction and reduce wear and tear.
Enhance corrosion resistance: the corrosion-resistant alloy material of the cladding layer can protect the ball valve from corrosion of chemical media.
Enhancement of high temperature resistance: the fusion cladding technology enables the ball valve to maintain good mechanical properties and oxidation resistance at high temperatures.
