Heat conduction oil and electric heater tell you the difference between a single head heating tube and a double head heating tube

From the structure of the heating pipe, the industrial heating pipe is mainly divided into single head heating tube and double head heating tube. The single head heating pipe is not as widely used as the double head heating pipe, but because of its own structural characteristics, it has been widely applied in some fields. The most common is the heating of the mould hole and the heating of the oil tank.

First of all, from the outside, the most obvious feature of the single head heating tube is the short volume. The volume of the heat-conducting oil heater is small, which has never affected its own power reduction, but the surface load is high.

In terms of service life, a single head heating tube is heated in a mold hole. To tell the truth, life is not as good as in theory.

High insulation performance. The single head electric heating tube has excellent insulation performance, and it can keep good insulation performance, especially in cold state.

Strong operability. When the single head electric heating tube is used, it is easy to complete the wiring in the box even if it is used more than one another.

Definition：

The tubular electric heating element is produced by the straight tube in the manufacturing process, which is made through the process of shrinkage tube, annealing, bend pipe and so on.

The single head electric heating tube, as the name suggests, means the tail is sealed, and the outlet or terminal is put out at the other end. For example, the electric heating tube of the extruding cylinder is a single head electric heating tube with limited stopper.

A double head electric heating tube is a lead or junction column at both ends of a straight tube, such as a double head air drying tube used in the painting room.

What is the difference between a single head electric heating tube and a double head electric heating tube?

The common point of the two is:

The tube surface of the single head electric heating tube and the double head electric heating tube are not charged.

All of them have the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation and long service life.

It can be used for heating in solid, liquid and gas medium.

The difference between the two:

In structure, the arrangement of the internal resistance wire is different.

In the environment, the single head electric heating tube is suitable for working in a heating environment that can not be connected at both ends.

Surface load design, single head surface load: 1-22w/cm2, double head surface load: 1-8w/cm2;

In the heating rate, the single head electric heating tube is small in volume and high in power, so it can be heated quickly, and it can reach 3~4 Baidu in a few seconds or even seconds.
