Flange Type Cartridge Heater, also known as flanged single head electric heating tube, is an important category in the single head electric heating tube family and is also known as bullet tube heater in foreign countries. It inherits the core structural characteristics of a single head electric heating tube with one end closed and one end wired, while innovatively adding a flange (flange) structure, perfectly solving the problem of inconvenient installation and fixation of ordinary single head electric heating tubes in some scenarios, becoming an ideal choice in the industrial heating field that combines practicality and stability.
1、 Product Overview
Flange Type Cartridge Heater, also known as flanged single head electric heating tube, is an important category in the single head electric heating tube family and is also known as bullet tube heater in foreign countries. It inherits the core structural characteristics of a single head electric heating tube with one end closed and one end wired, while innovatively adding a flange (flange) structure, perfectly solving the problem of inconvenient installation and fixation of ordinary single head electric heating tubes in some scenarios, becoming an ideal choice in the industrial heating field that combines practicality and stability.
This product has a metal tube as the outer shell, with high resistance electric heating alloy wire embedded inside, such as nickel 80 chromium 20, iron chromium aluminum, etc. The surrounding area is filled and compacted with high-purity magnesium oxide powder as the insulation and thermal conductivity medium. This structural design not only ensures efficient heating of the electric heating tube, but also has excellent insulation performance, enabling safe and stable operation in complex industrial environments.
2、 Core advantages
（1） Easy and stable installation
The flange structure is the iconic advantage of this product, as it can achieve a tight fit with the equipment and can be easily installed through bolts and other fasteners without the need for additional complex fixing devices. Whether it is plastic molding molds, pharmaceutical machinery, or packaging equipment, they can be quickly assembled, greatly saving installation time and labor costs, while effectively avoiding problems such as low heating efficiency or equipment damage caused by unstable installation.
（2） High power density, rapid temperature rise
Compared with traditional double head electric heating tubes, the Flange Type Cartridge Heater has a smaller volume but higher power density, with a surface load of 1-40W/cm ², and some high-end products can even reach higher levels. Under a fixed voltage, it can quickly heat up to several hundred degrees within a few seconds, meeting the demand for rapid heating in industrial production and significantly improving production efficiency.
（3） Strong adaptability and flexible customization
This product has a variety of pipe diameter specifications, covering sizes ranging from 2.8mm to 16mm. The pipes can be made of different materials such as SS304, SS321, SS316L, Incoloy840, etc., which can adapt to different heating media and environments, such as ordinary heating scenarios and corrosion-resistant scenarios. At the same time, voltage, power, length and other parameters can be customized according to customer needs to meet various personalized heating requirements.
3、 Application Fields
The Flange Type Cartridge Heater is widely used in multiple industrial fields due to its excellent performance: in plastic molding molds, it can accurately control the mold temperature to ensure the molding quality of plastic products; In pharmaceutical machinery, a stable heating environment can be provided for the drug production process to ensure drug quality; In packaging machinery, sealing components can be quickly heated to achieve efficient sealing of packaging materials. In addition, it is often used in scenarios such as food baking equipment, medical disinfection equipment, and heating systems for new energy vehicles, providing reliable heating support for the production and development of various industries.
