More particularly, the present invention relates to a heating jacket for outdoor piping, and more particularly, to a heating jacket for outdoor piping, in which, when supplying liquid or gaseous fluid used as a raw material or auxiliary agent in industrial production, The present invention relates to a heating jacket for outdoor piping, in which a temperature of a pipe is set to a predetermined level so as to be supplied smoothly.
In general, production facilities such as semiconductor manufacturing apparatuses and chemical processes supply liquid such as liquid or gaseous raw material or auxiliary liquid at a predetermined temperature level.
The supply of such fluid mainly uses piping as the supply passage. In the case of installing the piping, the room is not greatly influenced by the temperature change of the outside air. However, in the case of outdoor (outdoors) It is exposed to change and is relatively influenced by it.
For this reason, a heating jacket is installed in the outdoor piping so that the outside temperature of the winter does not affect the inside of the piping.
A conventional heating jacket has a first insulating material such as glass fiber having insulation and warming property along its circumference and a longitudinal direction on the outside of the pipe, a hot wire wound around the outer circumference of the first insulating material along the longitudinal direction, A second insulating material coated with a material such as glass fiber having heat insulation property, a temperature sensor provided in each section to check the temperature of each section of the pipe, gypsum water covering the outside of the first and second insulating materials and the temperature sensor, And a metallic lid which covers the exterior of the gypsum in order to prevent damage or breakage of the gypsum in response to an external physical impact.
Such a heating jacket of the related art may cause short-circuiting of the heating wire during use, partial damage or breakage due to physical impact, change of the pipe route, change of the pipe line, If you want to connect a facility or other piping that contains it, you have to first take the disassembly process from the piping.
At this time, the conventional heating jacket, which is disassembled from the piping, is not reusable and is wasted to be treated as industrial waste. In addition to difficulty in disassembling operation, it also takes a lot of time to reinstall a new heating jacket in the piping. There is a problem that the unnecessary workforce and cost are increased.
In addition, the piping is not placed in a uniform temperature environment in all the outdoor areas, and it is difficult to cope with a case where it is necessary to control at a partly different temperature for a pipe section requiring a specific condition, There is a problem of wasting energy.
