multiple pipes and tail -f

I have been trying to do the following but it doesn't seem to work.
tail -f <filename> | grep <some string> | grep <some other string>
where <filename> is the name of any file to which new lines are added,
something like a log file for example.
Is there some restriction on the number of pipes which could be used
while using tail -f ?
I would like use sed instead of the last grep in the example above,
but for simplicity I have used second grep.
Thanks and Regards,
