In blackwater and ash water systems, due to high concentrations of impurities, strong corrosiveness, and high-temperature, high-pressure working environments, traditional metal valves often fail to meet operational requirements and quickly corrode and damage, leading to frequent replacements and increasing operational costs and maintenance challenges. In practical applications within graywater systems, processes involving high-temperature water heaters, low-temperature water heaters, and vacuum flash tanks often experience corrosion perforation in ordinary metal pipes and valves. In severe cases, valves can perforate within 10 days of use, causing significant production difficulties for enterprises. However, Sun Yeh ceramic-lined valves, due to their unique materials and design, can effectively handle these challenges.
The application of Sun Yeh ceramic process piping and valves in such extreme conditions is mainly reflected in the following aspects:
1. High-temperature and corrosion resistance: Ceramic materials can withstand temperatures above 1000°C, and combined with suitable valve bodies, Sun Yeh ceramic-lined control valves can operate in conditions up to 500°C and have excellent resistance to acidic and alkaline substances. This allows them to operate stably for long periods in high-temperature and highly corrosive environments, which is crucial for blackwater and ash water systems.
2. Wear resistance and erosion protection: Solid particles in blackwater and solid components in graywater can cause severe physical wear and erosion to pipes and valves. Sun Yeh ceramic-lined valves, due to their high hardness and good wear resistance, can resist such wear, extending the lifespan of the valves.
3. Excellent sealing performance: In high-temperature, high-pressure conditions, the sealing performance of valves is a key factor in ensuring the safe operation of the system. Sun Yeh ceramic-lined valves are usually designed with special sealing structures that provide good sealing effects, preventing media leakage into the environment or causing losses during production.
4. Energy-saving effects: In graywater treatment systems, vacuum flash tanks can be used to recover heat generated in the process, thereby achieving energy savings. Sun Yeh ceramic-lined valves, due to their high-temperature resistance, are suitable for such equipment, helping enterprises improve energy efficiency.
Engineers select the most appropriate lining materials and valve designs for blackwater and graywater systems based on specific requirements. For instance, silicon carbide (SiC) may be chosen as the ceramic lining material for highly corrosive media. Overall, due to their excellent high-temperature resistance, corrosion resistance, wear resistance, and sealing capabilities, Sun Yeh ceramic-lined valves have become the ideal choice in blackwater and graywater systems.
