A hexagonal head heating tube is a tubular electric heating element that uses a metal tube as the outer shell, filled with crystalline magnesium oxide powder and wound with an electric heating wire, converting electrical energy into thermal energy for heating. Its features include:
Material and Structure
The outer shell is typically made of stainless steel 304 or 316L, filled internally with crystalline magnesium oxide powder for insulation and thermal conductivity, with a spiral electric heating wire embedded within. It has a compact structure, high mechanical strength, and supports horizontal or flange installation methods.
Specifications
Voltage/Power: Supports conventional voltages such as 220V/380V, with a power range of 3-12kW, customizable according to requirements;
Dimensions: Common tube diameters range from Φ6.6-16mm, with lengths varying from 20-6000mm;
Thread Specifications: Covers metric threads from M10 to M24 and imperial specifications such as 1 inch and 1.5 inches.
Application Scenarios
Widely used in water tank heating, boiler thermal oil heating, chemical equipment, and other scenarios, particularly suitable for industrial environments requiring high mechanical strength and corrosion resistance.
Usage Precautions
Must be installed horizontally with the liquid level above the heating zone to avoid dry firing or overheating due to impurity accumulation;
