Butt weld connection for pipes, esp. steam generator pipes - has a perpendicular pipe end to weld seam transition w.r.t.the pipe longitudinal axis

摘要

Butt weld connection for two pipes, esp. steam generator pipes, made of different materials, esp. ferritic/martensitic and austenitic materials with different coeffts. of thermal expansion, comprises a weld (5) between the two pipe ends (3,4). The transition from the pipe ends to the weld seam is perpendicular to the pipe longitudinal axis for connections where the difference between the thermal expansion coeffts. of the pipe and weld material is large.
