On the supply side, there are the following versions: — Fixed connection to connect a pipeline; — Permanently connected pipeline. On the consumer side there are the following versions: — Fixed connection; — Retrofitting connection. The overviews in Figure 1 and Figure 2 provide examples of connections for storing potable water. 4.2.2 Fixed connection 4.2.2.1 General information The fixed connection, see Figure 3, shall consist of a threaded pipe connection, a C coupling with dimensions as per DIN 14307-1 as a fixed coupling and a dummy coupling. 4.2.2.2 Fixed connection on the supply side The C coupling on the supply side, 4.2.2.1, shall be permanently connected to the threaded pipe connection. 4.2.2.3 Fixed connection on the consumer side The C coupling on the consumer side, 4.2.2.1, shall be permanently connected to a threaded pipe connection. The pipe shall be fitted with an ISO 228 – G 2 A pipe thread 20 mm long (DN 50). The pipe connection shall be welded firmly to the superstructure, the deck or the pipeline system and in such a way that its end is at least 300 mm above the deck. The C coupling shall be permanently attached to the pipe connection. 4.2.3 Pipe connector The pipe connector, see Figure 4, shall consist of a C coupling with dimensions as per DIN 14302, that is attached to the pipe by a pipe clamp as per 4.2.5 and a dummy coupling.BS EN 16865 pdf download.
