Document Type and Number:
WIPO Patent Application WO/2012/165869
Kind Code:
A3
Abstract:
The present invention relates to a flange assembly for a pipe joint having a clip hook coupling structure which includes a clip hook having a bolt insertion hole coupled to a hypotenuse protrusion disposed on an outer surface of a flange of the pipe joint, a bolt, and a nut. In the flange assembly for a pipe joint according to the present invention, the flange may be easily coupled and has a relatively small size when compared to a flange according to a related art. Also, an inner pressure on the flange and a bolt coupling compression force may be calculated in advance to adjust the numbers of clip hooks, bolts, and nuts. Thus, coupling costs and manufacturing costs may be reduced.
