Reasons and Treatment for Burnout of Air Electric Heating Tube

Reasons and Treatment for Burnout of Air Electric Heating Tube

Users who use electric heating tubes more often usually turn to reputable electric heating tube manufacturers to order electric heating tubes, because the electric heating tubes purchased from hardware stores quickly burn out, which is a common reaction among many customers. So today, we will mainly analyze the reasons for the burning of electric heating tubes. Our company has specially designed electric heating tubes with temperature control and protection to prevent burning out. Therefore, if you want the air dry burning heating tube to not be burned, you need to choose a high-temperature resistant electric heating tube material. There are two main reasons why the electric heating tube burns out:

1, Incorrect power design

Design power of 1-3KW per meter for water heating; (Power per meter refers to the power that an electric heating tube can carry per meter of heating area.)

The designed power per meter for corrosive liquids or water with poor water quality shall not exceed 2KW;

Oil heating with a designed power of 1-2KW per meter;

Air heating with a designed power of 1-1.5KW per meter;

The power design exceeds the above standards, and the more severe the deviation, the greater the possibility of the electric heating tube being burned out. We strictly choose the appropriate one.

2, Wrong material selection

1. Material selection during liquid heating;

Heat ordinary tap water and purified water, and use stainless steel 304 material normally;

Heating liquids or drinking water with weak acidity or alkalinity is recommended to use stainless steel 316 material;

For the selection of materials for heating other corrosive liquids, please refer to the material selection table for liquid electric heaters.

2. Material selection during air heating:

The working temperature is between 100-300 degrees, and it is recommended to use stainless steel 304 material.

The working temperature is between 400-500 degrees, and it is recommended to use stainless steel 321 material.

The working temperature is between 600-700 degrees, and it is recommended to use stainless steel material 310S.

For working temperatures between 700 ° C and 800 ° C, it is recommended to use imported Ingrid materials.

So the incorrect selection of material for electric heating tubes is also the main reason why electric heating tubes are prone to burning out.

Based on the above content, we analyze the causes of electric heating tube burnout, mainly due to incorrect power design and material selection. So before customizing the electric heating tube, everyone must inform the specific usage environment to avoid the situation of the electric heating tube burning out.
