<P>PROBLEM TO BE SOLVED: To provide a deformed pipe easy in its laying, in the cast iron deformed pipe having a deformed part such as a branch port part, a valve part or a bending part, and a laying method of the deformed pipe. <P>SOLUTION: This cast iron deformed pipe 1 includes at least one deformed part 2. Since the length of the deformed pipe 1 can be adjusted in response to positions of pipes on both sides of the deformed pipe 1 after positioning the deformed part 2 of the deformed pipe 1 so as to be set within an optimal predetermined installation position by providing a cutting margin L2 for adjusting the length in at least one end part of the deformed pipe 1, the deformed part 2 can be arranged in the predetermined position, and the pipe can be quickly laid without applying cutting work to the pipes connected to the both sides of the deformed pipe 1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
