Unnecerssary comment boxes appering in some pages

Hi,

I want to hide comment boxes from following pages of my site:

http://bit.ly/1R9eJ58
http://bit.ly/1iUa7V2
http://bit.ly/1Fs3aEK
http://bit.ly/1PHEMPL
http://bit.ly/1NUyMnC
http://bit.ly/1ViWrPl

I already tried page id.. comment box display: none, but it didn't worked. The comment boxes shouldn't display on those pages only.

How to achieve this?
Thanks.
