Description

Pipe heating cover

The present invention relates to a piping heating cover configured to be able to heat piping to prevent the piping from being frozen, and more particularly, to a piping heating cover which is provided with a hot line in contact with a piping, To an improved piping heating cover.

Generally, the freeze of the piping is that the water inside the piping keeps the liquid state and the freezing due to the freezing down of the air temperature becomes large, so that the pipe can not withstand the expansion due to the expansion.

In the situation where such pipes are exposed, the piping installed on the toilet or the road without the piping exposed, or the piping installed on the road does not have warmth when the temperature falls, so that the water inside the piping is frozen in the liquid state and the pipe ruptures Especially during late morning and early morning hours when there is no water use.

In order to prevent the pipe from being frozen as described above, conventionally, water is continuously flowed so that water is kept in a liquid state inside the pipe, so that there is a method of preventing the freezing of the pipe and a method of wrapping a heat insulating material The method of keeping warm was used.

However, among the methods of preventing freezing as described above, the former method has the disadvantage that it is the most reliable method to prevent freezing due to continuous flow of water and water in the inside of the pipe, Can eliminate the waste of water, but it has a disadvantage that the effect can not be expected in extreme cold such as below -10 ℃.

In order to solve all of these problems, there has been proposed a pipe having a built-in heating wire. However, the heat generated from the heating wire is not used for heating the pipe, and a large amount of the heat is discharged to the outside.

In order to reduce the outflow of heat generated from the hot wire to the outside, a method of wrapping one side and the other side of the outer surface of the pipe wound with the hot wire by a semi-cylindrical heat insulating material has been proposed. However, There is a disadvantage that heat escapes between the two insulation materials.
