<p>PURPOSE:To enable the intermediate connection of piping to be easily performed at a low cost by forming a joint to be used for the intermediate connection of piping continuing in the axial direction as a special joint whose insertion dimension is lengthened. CONSTITUTION:When pipings are respectively constructed from one side and the other side and the piping pipes from both sides are connected to each other on the half way, a joint 1 same as the conventional one is attached on one end of a piping pipe to be connected, while a special joint 2 whose insertion dimension is lengthened is attached on the other end so as to be slid freely (extended/contracted freely). When the piping pipe of the intermediate part is connected, the special joint 2 is slid outward from the axial direction after arranging the piping pipes in the state where the total length of the piping pipe including the joint is shortened by sliding the special joint 2 inward from the axial direction of the piping pipe and fitted in the other piping pipe to be connected, and then the connection of piping is completed.</p> |
