Industry Applications As a key component, valves are widely used in the fields of petroleum, chemical industry, electric power, metallurgy, etc. Under harsh working conditions such as high temperature, high pressure, and corrosive media, the valve sealing surface is prone to wear, corrosion, and leakage. Plasma cladding technology can significantly improve the performance and service life of valves, reduce production costs, and improve product performance. Frequently asked questions 1. Wear and tear problem: During the opening and closing process of the valve, the frequent contact between the hard sealing surfaces, valve seats and valve cores of the components can easily lead to wear, affecting the sealing performance and service life. 2. Corrosion problem: In the chemical industry, valves in strongly acid-corrosive working conditions are exposed to corrosive media for a long time, and components such as the valve seat, valve core and valve stem are prone to corrosion, resulting in valve failure. 3. High temperature and high pressure problem: Valves work in high temperature and high pressure environments, and the valve surface is prone to shedding and cracking. The cladding technology can greatly improve the bonding strength of the metal surface cladding layer, and the performance of component materials is prone to attenuation, affecting the stability and safety of the valve. Application components and their functions Valve seat: The contact part between the valve seat and the valve core is enhanced by plasma surfacing to enhance its wear resistance and corrosion resistance, ensuring the sealing and service life of the valve. Valve stem: The valve stem connects the valve core and the actuator. Plasma surfacing treatment can enhance its wear resistance and corrosion resistance and reduce failures caused by corrosion and wear. Inside the valve body: Plasma cladding is used to form an anti-corrosion coating on key parts inside the valve body to enhance the valve's tolerance to corrosive media. High performance alloy layer: Material selection: Use high-hardness metal powder or metal wire, such as cobalt-chromium-tungsten alloy, high-temperature nickel alloy, etc., and form a high-hardness coating on the surface of the valve seat, valve core and valve stem through plasma surfacing. Process control: Accurately control the plasma arc current, powder injection volume and welding speed to ensure good bonding between the coating and the substrate, forming a uniform and dense coating and improving the wear resistance of valve components. Anti-corrosion coating: Corrosion-resistant materials: Use materials with excellent corrosion resistance, such as nickel-based alloys and stainless steel powder, to form an anti-corrosion coating on the surface of key valve components through plasma surfacing. Coating thickness: According to the use environment and working conditions, adjust the coating thickness 0.5-5mm to ensure the long-term stable operation of the valve in corrosive media. High temperature stable coating: High temperature alloy: high temperature alloy materials, such as nickel-based and cobalt-based high temperature alloys, are used to form a high temperature stable coating on the surface of valve components through plasma surfacing to enhance the valve's tolerance in high temperature and high pressure environments. Coating structure: The microstructure of the coating is optimized to maintain good hardness and oxidation resistance under high temperature and high pressure. The metallurgical bonding strength of the high-efficiency alloy ensures the stable operation of the valve under harsh working conditions. Technical advantages: Intelligent Automation High precision and quality: Intelligent equipment can accurately control the processing process to ensure the quality and consistency of each processing. This high precision is difficult to achieve manually, reducing production problems caused by human errors, not only improving product quality but also reducing rework waste. Improve production efficiency: Under intelligent automation, one robot can better replace 2-3 experienced welders, better replace manual labor, and improve product production efficiency Flexibility and programmability: The robotic system can be programmed according to different workpieces and requirements, and can flexibly adapt to various complex processing tasks. This flexibility enables it to be competent for a variety of application scenarios, while traditional methods usually require more adjustments and manual intervention Better environmental protection process Reduce pollutant emissions: The cladding technology uses advanced welding technology, which can effectively reduce the emission of harmful gases and smoke. In contrast, the oxyacetylene electroplating process will produce a large amount of smoke and toxic gases, which have adverse effects on the environment and the health of operators. Efficient use of materials: Mechanical automation can accurately control the amount of materials used and reduce waste. This not only reduces production costs, but also reduces the generation of waste and helps protect the environment. Improve environmental protection: Mechanical automation technology reduces the emission of harmful substances, reduces smoke and noise pollution in the operating environment, improves the working environment of the factory, and better meets environmental protection standards
