PURPOSE:To eliminate generation of any corrosion, etc., in a fluid conduit by forcing a sealing resin into a clearance formed between a lined tube and the fluid conduit before a through-hole is drilled in the tube so as to seal the branch part of the tube. CONSTITUTION:The connecting male thread 3a of a branch joint 3 is screwed into the female thread hole 1a of a fluid conduit 1 so as to form the branch part of a pipe line. After a plastic system tube 2 is inserted into the fluid conduit 1, a through-hole 2a is drilled in a tube 2 in its area matching its branch part so as to open the branch part. A sealing resin A is forced into a clearance formed between the lined tube 2 and the fluid conduit 1 through the female thread hole 1a before the through-hole 2a is drilled in order to seal the branch in such a line tube. Thus the branch of the tube 2 is sealed to eliminate the generation of any corrosion, breakage, etc., in the fluid conduit 1.
