How to distinguish single head electric heating tube and double head electric heating tube?

The structure of the double-headed electric heating tube is different from that of the single-headed electric heating tube. The single-headed electric heating tube is sealed at one end, and the other end has a lead or terminal; terminal.

 

How to distinguish single-head electric heating tube and double-head electric heating tube can be through the following aspects:

 

(1) Structurally, the arrangement of the internal resistance wires is different;

 

(2) In terms of the use environment, the single-head electric heating tube is suitable for working in a heating environment where wiring at both ends cannot be performed;

 

(3) In terms of surface load design, single-head surface load: 1-22w/cm2, double-head surface load: 1-8w/cm2;

 

(4) In terms of heating speed, the single-head electric heating tube is small in size and large in power, so the temperature rises rapidly, and it can be 3 to 4 times in a few seconds or even a few seconds.
