Abstract

The outer diameter of the annular seat (5) of the pipe branch (3) to be welded and the corresponding seat (6) on a recess (7) in the wall (1) of the container around the hole (2) are roughly 2mm larger than the inner diameter regardless of the diameter of the hole (2). The axial length of two extensions (9,10) to the end of the branch is 2-3 mm. A ceramic support ring (11) fits into the hole to enter the branch with the hole during welding. The ceramic ring is removed after welding the branch and well.
