How do I select the wire and the thickness of the heating pipe manufacturer

It is well known that spiral heat wire diameter to the metal shell inner wall of the greater the distance, its electrical insulating pressure value is high, but the heat transfer path increases, the increase of the path is concatenated in the heat transfer path a attenuator, inevitably led to a decline in heating efficiency, the existing drawbacks and shorten the creepage distance is a decline in the normal pressure value will be larger, the key now is how to evaluate electric heating efficiency is low and influence on electric heat pipe performance and eventually make trade-offs

With magnesia as object describes the characteristics and creepage distance of the relationship between the electrical heating efficiency and heating pipe manufacturer but in addition to the above content has a greater effect on heating efficiency, and the last part of the heat transfer path, namely the shell material, in addition to the wall thickness of thermal resistance are linked, but also pay attention to in the present thermal resistance of the big four applied materials: the order from small to big basic copper aluminum < < < iron stainless steel, according to the actual permit conditions as far as possible with good thermal conductivity materials, this to improve the performance of electric heating efficiency and heating tube life have a certain role in promoting.

1, 304 stainless steel material. Make more for the stainless steel heating tube, is 304 stainless steel material, such as heating in liquid and air heating and its comprehensive performance is pretty good and the price is moderate, so the applied in heating tube manufacturing.

2, 301 stainless steel material. Frequently occur in the process of machining deformation, hardening of the phenomenon, so much is used for all kinds of high strength.

3, 302 stainless steel material. 302 compared to 304, the carbon content is higher, so after cold rolling strength is higher.

4, 303 stainless steel material. Sulfur is contained in stainless steel 303, 303 stainless steel material, so more convenient for cutting and requiring higher on stainless steel surface finish.

5, 304 l stainless steel material. Carbon content is low, when welding the decomposition of carbide is little, so to reduce carbon emissions.
