The chambers are separated from one another by baffle creases unitary with the respective external shells. Portions of the baffle creases of one external shell are secured in face-to-face contact with corresponding portions of the baffle creases in the other external shell. The baffle creases comprise arcuate portions corresponding to the shape of the pipes passing between the chambers separated by the baffle creases.
