<p><P>PROBLEM TO BE SOLVED: To easily connect mutual pipes in a sealed state, while allowing axial dislocation and parallel dislocation. <P>SOLUTION: Packing is arranged between both side surfaces, and is formed in a shape having two tongue pieces projecting to the pipe inside and a trough groove formed between these tongue pieces in a state of being fitted to a packing fitting groove, and connects both pipe ends by fastening of a bolt extended between a bolt insertion hole formed on the flange pipe end and a loose flange. The packing is solved by a pipe coupling structure sandwiched between the pipe ends in a state of forming a clearance for introducing fluid to the trough groove. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
