Pipes

Pipe placement is important. If you want to remove items from a furnace, for example, then a wooden pipe needs to be attached to the side of the furnace. A pipe connected to the top of a furnace places items into the top spot, and a pipe connected to the bottom of a furnace puts items into the bottom spot.

Wooden Pipe
Wooden pipes are for extracting items from any container (e.g. furnace, chest and other things that may hold items). It must be powered by an adjacent engine to function.

Cobblestone Pipe
Cobblestone pipes carry items along the pipe network. They will not connect to stone pipes.

Stone Pipe
Stone pipes carry items along the pipe network. They will not connect to cobblestone pipes. They will also continue the speed effects of powered gold pipes more efficiently than others.

Iron Pipe
Iron pipes have only one output. It can be changed with redstone or a wrench. They can't output into a wooden pipe.

Gold Pipe
Gold pipes can boost the speed of items passing through them when supplied with a redstone current

Diamond Pipe
Diamond pipes can filter items to different output pipes based on a user-defined filter.

Obsidian Pipe
Obsidian pipes will pick up items off the ground. Their collection range will increase when powered by an engine.

Stripe Pipe
Only available in BC for MC1.2.5, stripe pipe will place, pick up or use an object that is in front of it when powered by an engine.

The stripe pipe can also be used to autobuild a transport pipe. Simply place it on the end of a short length of transport pipe, then send more transport pipe down the pipe. The stripes pipe will replace itself with the new section of pipe and move one square forward.
