Procurement personnel often ask: In what scenarios are flange-type electric heating tubes suitable? The FJ-48 model uses round or square flange connections and can be installed on reactors, storage tanks, pipelines, and other equipment for heating liquids and gases. Voltage options include 220V or 380V, and a temperature controller can be installed in the wiring chamber as needed for on-site temperature control.
During installation, ensure the flange matches the equipment interface and the sealing gasket is intact to avoid leakage. The surface of the heating tube should be protected from impact, and insulation resistance should be checked before use. Regularly removing surface dirt helps maintain thermal efficiency. It can be used normally in environments with ambient temperature of -20℃ to +60℃ and relative humidity below 95%.
Select the appropriate tube material and power density based on the heating medium, working temperature, and power requirements. For corrosive media, stainless steel or more corrosion-resistant materials can be selected. When installing a temperature controller in the wiring chamber, confirm that the temperature control range matches the process requirements.
Q: Can the heating tube be used in flammable and explosive environments? A: The standard model is not suitable for explosion-proof applications; if explosion-proof requirements exist, explosion-proof electric heaters should be selected. Q: How can I determine whether the heating tube needs replacement? A: When insulation resistance decreases or heating efficiency drops significantly, inspection or replacement is recommended.
