At this time, as described above, it is necessary to install at least one sprinkler in the inside of one building for safety. Therefore, unnecessary economic costs are incurred as the repairing work is continuously generated due to the breakage and leakage occurrence, The sprinkler does not function in case of an emergency, so that it is impossible to prevent the human or material damage in the building. Therefore, measures are urgently needed.

Meanwhile, as a fire-related sprinkler and pipe-related prior art related to the above-mentioned building, Patent No. 10-1332558 discloses a CPVC fire-fighting sprinkler system using a mechanical coupling device and a supporting device and a method of assembling the same. However, the above-mentioned patent discloses a method of coupling pipes and an apparatus therefor, and is a technology independent of the present invention relating to a sprinkler end pipe.

And JP 10-1047190 discloses a CPVC transparent joint pipe which is used as a transparent CPVC raw material for a pipe connection pipe in a fire pipe system or a fire fighting sprinkler system. However, the above-mentioned patent is also a pipe coupling device using a transparent CPVC, and its feature is transparent, so that the visual inspection of the welded portion of the solvent inside the joint pipe is important. It is a technology.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the related art as described above and provides a CPVC sprinkler end pipe for CPVC which is formed of a CPVC material as a sprinkler end pipe and is connected to a water supply pipe similarly formed of CPVC material, There is a purpose.
