As far as I know, BatchPipes is a separate concept from TSO Pipelines. Separate jobs use the SUBSYS keyword on a sequential file output or input DD statement to route management of that DD statement to the BatchPipes subsystem address space, with other SUBSYS keyword options to handle the routing. The server can then connect the DD statement with a similar DD statement in a different batch job, providing buffering as necessary. Existing programs just think they are just writing or reading normal sequential files. BatchPipes supports the use of TSO Pipelines "fittings" which can be inserted in the pipes connecting the jobs, for example allowing the data to be transformed, split or duplicated to different destinations. The copy of TSO Pipelines supplied with BatchPipes is called BatchPipeWorks, and can also be used in the same way as TSO Pipelines.
For more details, you need to find a way to read the documentation that I mentioned in my earlier post.
