The general convention in Wireshark-the-project (i.e., Wireshark, TShark, and dumpcap) is that if the "network interface" you specify isn't a network interface (i.e., an attempt to open it with libpcap fails), and it's a named pipe, it's opened as a pipe connected to a program writing a pcap (or pcap-ng?) capture file.
I.e., in the GUI, you'd specify it by, for example, giving "/tmp/pipe" (or whatever the named pipe path is) as the name of the "network interface" from which to capture in the Capture Options dialog.
