A process for bending a discharge tube for internal combustion engines involves inserting a flexible part into the tube before bending

摘要

A process for bending a discharge tube (1) in which a flexible part (2) is inserted coaxially into the discharge tube before the tube is bent. The flexible part has at least some areas (3i) of its external walls contacting the internal surface (1a) of the discharge tube perpendicular to the longitudinal axis (L-L).
