Abstract: The exchange unit includes a first flow path end portion having a first width; a main body portion having a second width larger than the first width; a second flow path end portion positioned on a side opposite to the first flow path end portion; and a slide extension portion including a portion larger than the first width and is configured to cover the first flow path end portion on an outer side of the first flow path end portion, and a portion larger than the second width and is configured to cover the main body portion on an outer side of the main body portion. The exchange unit is removably mounted to an existing pipeline with a distance between an upstream-side end portion of a pipeline and a downstream-side end portion of the pipeline being invariable only by a translational operation without using a rotating operation.
