The joint is provided for piping composed of a main pipe, a first side pipe and a second side pipe. The first side pipe is joined on the downstream side of the main pipe to the upper surface thereof, and the second side pipe is joined on the upstream side of the main pipe to the lower surface thereof. The positions where the first side pipe and the second side pipe are joined are on the opposite sides to each other with respect to the main pipe, and confront with each other. The axis of the extended center line of the first side pipe and the axis of the extended center line of the second side pipe are parallel to each other, and the first side pipe and the second side pipe are inclined at a predetermined angle made between the axis and the axis of the extended center line of the main pipe, and joined to the main pipe. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
