摘要

The device is made of a welded construction with pipe sections that are butted together and welded. The base body consists of two welded pipes in the form of a pipe-connector combination. The pipe (2) and connector (3) have weld seam surfaces (4,5) that are mating, saddle-shaped and parallel to each other and have identical inclination angles forming a weld seam angle between 0 and 90 degrees. AN Independent claim is also included for the following: a method of manufacturing a base body of joined pipe pieces.
