OK - I think I remember how I did this before.
I connected a physical tape drive to my Linux box, used tapecopy to
write the SimH-format tape image to tape, then used standard Linux
utilities to read individual 'files' off the tape.
What I was hoping for was a way to skip the physical tape stage and read
'files' (i.e.blobs) from SimH-format tape images.

For the PDP10, there are utilities that can be compiled for linux that

tapecopy, tapedump, and t10backup are part of that package. There is
also read20 that can extract files from a TOPS20 dumper tape.

I should have said that the tape image contains a number of data files -
which I can process - but I need to extract each individual files
first. I did do this a while ago using tapecopy or tcopy or mt or
something-or-other...

extract a tape dump in SimH format
Can you be a little more detailed here. The file is a SimH format of
the a tape. But the tape itself has been formatted by the application
on the OS that wrote it.
eg. if its a UNIX "dump" format tape you need: something to under
the SimH format and create a bytes stream to push into a program that
understand the UNIX restore format - which also means you might have
NUXI issues depend on the simulator that wrote it, since dump writes
integers in native formats in the metadata.
or if it's a TOPS "dumper" (aka backup) you will need something to
under the SimH format and create a bytes stream to feed program that
understand the PDP-10 dumper format.
FYI: I used to have tools for the later part, although I have never
run them on Linux. The last time i ran them was an Alpha under Tru64.
I'll have to go digging.
