The Extra Utilities pipes are disabled. I forget why, but Eyamaz disabled those very early on. Normally they have a Recipe and the description you see in NEI. But since the receipe is disabled, you only see the description now.The Extra Utilities pipes? They do sound cool but how do I get recipes on those? If I click them in NEI or hit R I get a description of what they do - which is great to have (I wish everything had that) - but no recipe. I tried the default recipe from the wiki for sorting pipe and it didn't work.
There are pipes that are kind of like logistics pipes in the Red Power-Transport mod. They can do storage and even crafting and stuff, but of course take quite a bit to craft, set up, and get working right.
