Flange Type Cartridge Heater: an efficient choice for industrial heating
In the field of industrial heating, Flange Type Cartridge Heaters have become an ideal heating solution for many scenarios due to their unique structure and excellent performance. It combines the high power density advantage of a single head electric heating tube with the convenience of flange connection, providing reliable support for heating and insulation of liquids, gases, and even low melting point metals.
Structure and Working Principle
The core structure of a Flange Type Cartridge Heater consists of a metal protective tube, a high resistance heating wire, an insulated thermal conductive filler, a flange plate, and a wiring device. Metal protective sleeves are often made of materials such as stainless steel 304 and 316L, which have both corrosion resistance and high strength characteristics; The internal nickel chromium or iron chromium aluminum alloy heating wire generates heat through the current heating effect after being energized; High purity crystalline magnesium oxide powder is tightly filled between the heating wire and the protective sleeve, achieving electrical insulation and efficient heat conduction; The flange serves as a connecting hub, and is firmly connected to the container or pipeline through standard industrial flange specifications such as national standard GB, American standard ANSI, etc., to ensure installation sealing and pressure bearing capacity.
Its working principle is simple and efficient: current flows through the heating wire to generate Joule heat, which is quickly conducted to the surface of the protective tube through magnesium oxide powder, and then exchanges heat with the heated medium to achieve precise temperature control and rapid heating.
performance advantage
High power density: The surface power can reach 2-4 times the air heating load, with a single power range covering 3KW to 150KW, which can meet the demand for significant temperature rise in a short period of time.
Easy installation: The flange connection is a standard industrial assembly method that can be installed by tightening bolts without the need for additional brackets. It is suitable for complex working conditions such as vibration and impact, and is easy to replace with a single unit, reducing maintenance costs.
Strong adaptability: Special materials such as titanium alloy and PTFE coating can be selected for protective sleeves according to the characteristics of the medium, suitable for corrosive and easily scaling media; Supports multiple voltage specifications such as 220V/380V, paired with PID temperature control system and over temperature and low liquid level protection devices, to achieve intelligent and safe operation.
application field
Widely used for heating crude oil storage tanks and temperature control of reaction vessels in the petrochemical industry; Fermentation tanks and sandwich pots for insulation in the food and pharmaceutical industry; Heating of hot water tanks in the water treatment industry; And the heating up of plating tanks in the electroplating industry provides strong guarantees for the efficient and stable operation of industrial production.
