You cannot use redstone tubes with buildcraft machines. You can pump items into a chest and pump them out using a filter or a sorting machine. You can also use an ejector or a relay to connect the buildcraft pipes to a pneumatic/redstone tube system.

I would only use buildcraft pipes when necessary. If you plan on useing a world anchor to keep your machines running, the builtcraft pipes can back up causing serious lag or ultimatly crashing a server. You can install a safety for this issue if you are going to use the buildcraft pipes. Use a transposer 1 block above the pipe connected to a chest. Use a timer and redstone tubes to power the transposer. If an item backs up in the pipe, the transposer will pick it up. Then you can pump it to another chest or an incinerator.

We crashed a server using a quarry. The items were backing up in the tube, as time went on there were several thousand blocks in one section of the pipe. The cpu was totally overloaded trying to keep al those loaded and the game was completely unplayable. We ultimatley had to restart the server.
