ABSTRACT:
A branch pipe joint for a high pressure fluid, comprising: a joint body having a conduit therein on its axis and a branch hole formed in its circumferential wall and having a pressure receiving seat formed on the circumferential face thereof and opened to the outside; a branch pipe having a conduit to communicate with the conduit of said joint body and including a joint head formed at the end thereof and forming a pressure seat so that said branch pipe is engaged with said joint body by bringing the pressure seat thereof into abutment against the pressure receiving seat of said joint body; a joint portion made integral with or separate from said joint body; and a nut assembled in advance in said branch pipe and fastened into said joint portion against the pressure of said joint head thereby to joint said branch pipe to said main pipe. The branch hole at said joint body is formed into an elliptical hole having a longer diameter in the radial direction of said joint body and aligned with the center of the conduit of said joint body.
