What is the difference between a single headed tube and a double headed electric heating tube
Many customers are asked where to use the electric heating tube when purchasing it, whether it is a single headed tube or a double headed electric heating tube. Customers are not clear about it and only know that it is a straight rod type. They only know which type it is by sending pictures through WeChat. Below, we will share the similarities and differences between single headed tubes and double headed electric heating tubes.
1、 Definition:
Tubular electric heating elements are manufactured using straight pipes and processed through processes such as shrinking, annealing, and bending.
(1) As the name suggests, a single headed tube means to seal the tail and stop at the other end with a lead or terminal; An electric heating tube with an extrusion tube is a single headed tube with a limit stop.
What is the difference between a single headed tube and a double headed electric heating tube?
(2) Double headed electric heating tubes have leads or terminals at both ends of the straight tube; A double headed air dry burning electric heating tube commonly used in paint baking rooms.
What is the difference between a single headed tube and a double headed electric heating tube?
2、 What is the difference between a single headed tube and a double headed electric heating tube?
A. The commonalities between the two
(1) The surface of both single headed and double headed electric heating tubes is not charged;
(2) All have the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation, and long service life;
(3) All can be used for heating solid, liquid, and gas media.
B. The difference between the two
(1) Structurally, the arrangement of internal resistance wires is different;
(2) In terms of usage environment, single headed tubes are suitable for working in heating environments where wiring at both ends is not possible;
(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 tube has a small volume and high power, so it heats up quickly, and can instantly reach 3-4 Baidu in a few seconds or even a few seconds.
