Export Pipeline - definition

[Nurikos]

Dear all,
Could you provide a definition of "export pipeline" by any standards or institutions, please? I would also appreciate your sources and references for this term as I would need a back up

Thanks

The term sounds obvious, but when I tried to look for a clear definition to use in my presentation slides I could not find anything in SPE and even wiki. I would appreciate your help!
