Abstract

PURPOSE: To make it possible to easily perform field welding of the branch piping and the header piping and to make the pickling work unnecessary, by welding the reinforcing material to the end of the branch piping and welding the reinforcing material and the header piping.
CONSTITUTION: The reinforcing ring 12 is welded to the end of the branch piping 11. This unified stock is welded to the header piping 26. The reinforcing ring 12 is made to contact the outside of the header piping 26, and its contact face is worked so that it can match the outer diameter of the header piping. As for the header piping 26, a necessary hole 27 is worked at the position to which the branch piping is connected. At the time of welding, the inside surface of the header piping is heated indirectly, therefore it is prevented from being oxidized by carrying out back-sealing by use of inert gas such as argon, etc. In case field welding is performed for the outer circumference of the reinforcing ring 12, padding can be made comparatively freely, therefore it is possible to make the pickling work on the spot unnecessary by carrying out welding of high connected strength.
