Corrosion-resistant (corrosive-resistant) heat tracing sampling composite tubeElectric Trace HeatingEquipment is designed to increase flue gas temperature, ensuring complete vaporization of moisture within the flue gas and preventing gaseous pollutants like SO2 from dissolving in water, which could lead to measurement errors. Therefore, temperature control is required to be around 150 degrees. When selecting corrosion-resistant, heat-tracing, and sampling composite pipes, it is essential to know their type, typically including self-limiting temperature electric heat-tracing and constant power electric heat-tracing, as this facilitates different maintenance approaches.
