Document Type and Number:
WIPO Patent Application WO/2021/167351
Kind Code:
A1
Abstract:
The present invention relates to a coupling assembly for branching a pipe and, more specifically, a coupling assembly for branching a pipe, which can reduce assembly man-hours, has a simplified configuration, thus enabling a reduction in construction costs, and can effectively prevent the leakage of branched fluid even when the diameter of a branch hole formed in an inlet pipe is increased in order to increase a flow rate inside a branch pipe for supplying fluid to a sprinkler. To this end, the coupling assembly according to the present invention comprises: an inlet pipe having a branch hole for branching an inflowing fluid; a branch pipe in communication with the inlet pipe to allow a fluid branched through the branch hole to flow therethrough; and a coupler which interconnects the inlet pipe and the branch pipe, wherein the coupler has an extension portion which passes through the branch hole and is inserted into the inlet pipe, and the inner diameter of the extension portion is the same as the inner diameter of the inlet pipe or greater than the inner diameter of the inlet pipe.
