Corrosion-resistant (corrosion-proof) heating sampling composite pipes are equipped withElectric heating tapeEquipment designed to increase flue gas temperature, ensuring complete vaporization of moisture within the flue gas, and preventing the dissolution of gaseous pollutants like SO2 into water to avoid measurement errors. Therefore, temperature control around 150 degrees is required. When selecting anti-corrosion and heat tracing sampling composite pipes, it's crucial to know their type, typically including self-limiting temperature electric heat tracing and constant power electric heat tracing, which facilitates different maintenance methods.
