Abstract
The invention relates to a header for a high-pressure apparatus of steam power plants, with the header comprising at least one pipe nipple for welding on pipes for feed water and the pipe nipple protrudes to the outside from the header wall. In the header in accordance with the invention, the pipe nipple is formed integrally from the header wall. As a result, a weld joint between pipe nipple as a first part and the wall of the header as a second part can be omitted, so that the production effort is reduced considerably in the case of large headers with many pipe nipples.
