Seems its boblogistics doing it, I also note that boblogistics renames pipe into Iron pipe. Does that have something to do with it?

Suggestion to support recycling of Flow Control mod

So it seems that when i mine up a iron pipe I get an elbow pipe back

I'm using some mods but the ones affecting pipes beside this one are small fixes, squeak thorough, boblogistics and zgroupchange.
