The stainless steel flange heating rod is an industrial electric heating element that enables quick sealed installation through flange connections, primarily used for heating and maintaining the temperature of liquid or gaseous media. Its core structure consists of a stainless steel seamless tube, resistance wire, and magnesium oxide powder, utilizing argon arc welding technology to ensure sealing integrity and supporting single-unit replacement to simplify maintenance.

Core Structure
Composed of multiple U-shaped electric heating tubes welded onto the flange, with surface power reaching 2-4 times the air heating load. It withstands temperatures up to 900°C, with the main body made of SUS304 stainless steel, equipped with a PID temperature control system for ±1°C precision adjustment, and integrated with over-temperature/low liquid level interlock protection functions.
Installation Methods
Supports both flange-type and threaded end-face sealing connections, compatible with various specifications such as DN80-DN450. It features high surface power density and a compact structure that requires no additional brackets, widely used in storage tanks, circulation systems, and other applications in the petroleum, chemical, food, and machinery industries.
Key Features
