Frequently Asked Questions
Q1: What chemicals are graphite heat exchanger plates resistant to?
A: Impermeable graphite is resistant to most acids (except hydrofluoric acid and concentrated nitric acid), alkalis, and organic solvents. It is widely used for sulfuric acid, hydrochloric acid, and phosphoric acid applications.
Q2: What is the maximum operating temperature?
A: Resin-impregnated graphite plates typically operate up to 180°C. Higher temperature grades are available with special impregnation.
Q3: Can you machine custom flow channels on the plates?
A: Yes, we can mill custom flow channel patterns on graphite plates according to your heat exchanger design specifications.
Q4: How do I know if graphite is suitable for my application?
A: Please contact us with your specific chemical media, temperature, and pressure requirements. Our engineering team will recommend the appropriate graphite grade and impregnation.
