摘要： PROBLEM TO BE SOLVED: To improve assurance and reliability of decision on an inspection result of airtightness of a main plug to close a boring control port after take-out of chips, in a joint for active pipe branch wherein chips are stored in a chip tray after boring of an original pipe by a hole saw, and then taken out. SOLUTION: A pair of first and second division joints 4 and 5 are conjugated with a part in an axial direction of an original pipe 1 and a branch pipe 2 is connected to a branch pipe connection port 13 of the second division joint 5. The chip tray 15 in which chips 42 generated due to boring 40 by the hole saw are stored is lifted until it is fitted in the internal part of a seal ring 21 and a boring control port 14 is temporarily closed in an airtight state. When, after the chips 42 are recovered under an airtight state, an original plug 45 is fastened against the boring control port 14, the chip tray 15 in a seal ring 21 is pressed down to a position above an elastic ring 52 by a tray pressing down member 56. Thus, airtightness by the chip tray 15 through fastening effected by the original plug 45 is reliably released and decision on a result of original airtightness inspection of the original plug 45 is reliably made.
