Analysis of standard diameter specifications and specifications for single ended electric heating pipes

A single ended electric heating tube is a metal tube filled with high resistance electric heating alloy wire heating material. It is filled and enriched around the electric heating wire, with good insulation performance, and can use high-purity magnesium oxide with high thermal conductivity as the filling material. It has high power, high thermal efficiency, and fast heat dissipation, and can be used for heating plastic packaging, small mold heating, analytical instruments, and various gas expansion cooling effects.
Introduction to Single End Heating Tube
1. Pipeline heater: Electric heating pipes are mainly used to install in the blowing pipeline of the air heating system for blowing hot air. It can also be used as a heating element for various ovens and electric furnaces.
2. Nitrate solution solution, oil, and water heating: formed by welding bent tubular electric heating elements onto flanges. Electric heating tubes are used for heating in open and closed solution tanks and circulation systems.
The formula for calculating the wattage of a single ended electric heating tube is:
eight × π × L (cm) × W/cm2=W (total power of each electric heating rod)
(π=3.1416) (L=length of heating part) w/cm2 (watt density)=normal 6-8w/cm2
High watt density heating tubes (above 8w/cm2) can be customized according to actual needs.
Technical specifications of single end electric heating tubes
1. Usage conditions: Environmental temperature -20 ℃~+60 ℃, relative temperature<80%;
2. Electrical strength: Cold state withstand voltage AC working 1500V 50Hz for 1 Min without breakdown phenomenon;
3. Thermal insulation performance: AC 1000V 50Hz for 1 Min without breakdown phenomenon;
4. Leakage current<0.5Ma; Insulation resistance>30M Ω;
5. Power deviation+5%, -10%;
