Pipe connection a direction with a double pipe and a process for the preparation of a tube connection a direction with a double pipe as well as exhaust manifold with double pipe for an internal combustion engine

摘要

there is a connection between a cylindrical end piece of a doppelrohres and united the cylindrical end of a pipe is described. the cylindrical tail shows diametrically opposite parts of the respective grooves in the axial end of the cylindrical member by a circular tail).the cylindrical end of the tube has diametrically opposite parts to each slit in the axial end of the cylindrical tail of a circular cover. the cylindrical end of the doppelrohres united in the cylindrical end of the tube such that the grooves in each of the slots are in addition to and these are aligned.the circular end of the tube is fully on the outer surface of the cylindrical tail of the united doppelrohres welded and the edges of the slots, each of the corresponding grooves, welded to the pipes to air link.
