Connecting piece for the fluid circulation with inner circulation pipe for a service water or heating water supply facility, pipe assembly with such a connecting piece and method for assembling such a pipe assembly

摘要

The piece (20) has a connector (9) for connecting an inlet pipe (2) and another connector (10) for connecting an upstream pipe (3). A third connector (11) is arranged in the latter connector for connecting a conduit pipe (4a) of an inner circulation pipe (4) that proceeds in the upstream pipe. A fourth connector (12) connects a radiating conduit pipe (4b) of the inner circulation pipe. A passage (16) is provided for the inner circulation, where the inner circulation water is diverted at 90 degrees in the passage. An independent claim is also included for a method for assembling a pipe assembly.
