<p><P>PROBLEM TO BE SOLVED: To provide a piping method which can improve the efficiency of the piping work by reducing the number of pipe fittings to be used and reduce the working cost and the component cost. <P>SOLUTION: When piping, etc. are arranged in a building, etc., a piping member 1 is preliminarily manufactured using a straight junction pipe 2 and a fitting 3 welded at one end of the junction pipe 2. In a construction site of piping, etc., the piping member 1 is connected to the piping, etc. in the building, etc. via pipe fittings 7. When the junction pipe 2 is cut off in the construction site, the junction pipe 2 can be easily cut off because the management of the gap formed between the junction pipe 2 and the fitting 3 may be done at only one place. In addition, the generation of the leakage of fluid from the pipe fittings 7 after construction can be surely prevented because of the improvement of the precision of the gap, and further the efficiency of the piping work can be improved, and the component cost can be reduced because the connecting portions by the fittings 7 are reduced by the number of the reduction of the fittings 7 to be used. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
