【20mm electric cartridge heater recommended specifications】

Electric cartridge heater is a kind of electric heating tube (tubular electric heating element). In China's electric heating industry, there is a model called M3 for a long time. Due to the widespread use of electric heating tubes in China in the late 1990s, China has now had a complete product line for many years. There are already many shapes of electric heating tubes

The common specifications of a 20mm electric cartridge heater are recommended as follows:

Note①: Suggestions for material selection (note: this material is a suggestion, not unique):

Surface load ≤6W/ cm2-SS304;

6W/cm2＜surface load≤ 12W/cm2 – SS321 or SS310S;

12W/cm2＜surface load≤ 20W/cm2 – SS310S or Incoloy 800/840

Note ②: The maximum operating temperature of 700℃ refers to the use of SS310S or Incoloy800/840. This temperature is used for a 1-year warranty in an embedded dry burning environment, and 3 months in bare air dry burning environment. [Note that China's low-end single-head tube embedded dry-burning uniform warranty is 3 months (low-cost performance, not recommended)]

Electric cartridge heater accessories selection:

The limit piece is optional, please provide the shape and size of the limit piece

Built-in thermocouple, generally optional K or J thermocouple

Outgoing wire protection, generally optional metal hose outgoing protection, metal braided wire outgoing protection

The heat sink is generally used for air-dry burning to expand the heat dissipation area.
