Conventional sprinkler joints have more than 6 spots of jointing with the risk of water leakage as their elbow and reducer are
assembled and connected after screw processing is done on the tips of the both sides of a steel pipe. It is quite hard to adjust
location of the sprinkler head up or down or right or left. Also, installation of the equipment on the narrow ceiling requires highskilled
construction workers and long time due to the obstacles of the structure such as air-cooling, heating ducts, electricity and
communications facilities.
Sprinkler flexible joints supplied by Dong-A has obtained quality certification from UL, FM(USA), VdS(Germany), FESC(Japan) and
KFI(Korea), and are used for high pressure as their nipples, reducer, and stainless steel flexible tubes are all combined in one body.
With only two joint points, the risk of water leakage has greatly reduced. And as it is flexible, even unskilled workers will find it easy
to work with the tubes. It can cut down installation costs dramatically with the time spent for the construction greatly reduced by
more than 20 times than that of steel pipe type. With the quality certificate obtained in U.S.A., Britain, Germany, and Japan, the
high quality of this sprinkler system has been widely proven.
