Stainless steel flange heating tubes are industrial electric heating elements that utilize concentrated heating through flanges, primarily used for heating liquid or gaseous media, commonly found in storage tanks, pipelines, and circulation systems. Their core structure consists of stainless steel seamless tubes, high-temperature resistance wires, and crystalline magnesium oxide powder. Multiple heating tubes are connected to the flange cover via argon arc welding or fastening devices, with surface power reaching 2-4 times the air heating load.

Classification and Specifications
Based on flange type, they are categorized into threaded flanges (1-2 inches) and flat flanges (DN10-DN1200). The former is suitable for low-power scenarios (a few kilowatts to tens of kilowatts), while the latter can handle high power (several kilowatts to hundreds of kilowatts).
Structure and Manufacturing Process
Heating tubes are fixed to the flange using argon arc welding or fastening devices, ensuring excellent sealing and allowing individual tube replacement. The interior is filled with magnesium oxide powder to enhance thermal conductivity, resulting in high thermal efficiency and uniform heat distribution.
Application Scenarios
Widely used in petrochemicals, food processing, mechanical manufacturing, and other fields, such as heating liquids/gases in storage tanks, pipelines, and circulation systems, compatible with 220V/380V voltage.
Features
High Sealing Performance: Argon arc welding ensures long-term stable operation.
Easy Maintenance: Individual heating tubes can be replaced independently, reducing maintenance costs.
