If you are working on Oracle 8i then use the following. You dont need pipe.
Exp scott/tiger file=file1.dmp,file2.dmp……FILESIZE=10M
Use other parameters also as per your need. Oracle 8i has FILESIZE parameter that breaks the file into smaller pieces.
You can use pipe in prior versions.
To export to a compressed file:
$mknod pipename p
compress < pipename > newfilename.Z &
exp <username>/<password> file=pipename
rm -f pipename
To import from a compressed file:
$mknod pipename p
uncompress < newfilename.Z > pipename &
imp <username>/<password> file=pipename
rm -f pipename
