A slanted pipe would be nice - kind of like the one found here: http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=339694286
So many conveyor packs don't have these but they come in handy in so many cases, especially for visible external conveyor lines.

I don't really see the difference between a curved pipe and these (in functionality, I mean)
The purpose of the pipes besides their function is to be rounded instead of blocky like the vanilla ones.
Thanks for the feedback nonetheless!

It's purely for looks. The slants allow for diagonal conveyor line connections where otherwise one would need to use multiple corner pieces (which looks bad and isn't likely to be build in the real world) or straight conveyor lines, which means they would extend beyond where one would want to build. It's especially useful if you're having your conveyors follow slanted blocks along the outside of a ship - can't follow along them if the conveyors can't physically match them.

The way I see it, the pipes would still be round, it would just add a new dimension of building because one won't run into this problem as much anymore:

Then then again as I said, it's purely cosmetic. I just think it'd be nice to have the option.

You raise a good point, I will add them soon ;)
But I hope you know that if I don't want to break the design (which I won't) it may look a little bumpy because of the connectons are slightly wider than the tubes.

It became a little wider overall, but looks better than a bumpy variation I tried earlier.
Enjoy, and thank you for your suggestion!

Cool! It looks pretty good. Thanks for the addition!

I have a request; can you make the large pipes hollow, so a player can move through them, along with a hatch for entry? This includes the junctions :D

Im working on them right now, BUT they will come in a separate mod.

I added maintance tunnels (conveyors which can be used as passage ways too) as a separate mod.

How about an end cap? Like a rounded cap. Wouldn't serve much purpose other than visuals but would like very nice I think.

There is already one :)

Think you could you add an armor block version of the pipe/tube for when you take a pipe/tube from inside the ship to the outside? As it is, extending the convyeor system outside the ship leaves space in-between the pipe/tube itself and the surrounding armor blocks.

Just search for armored conveyors, like this:

I supose, but I'd need a whole other mod with numerous blocks which I in the end won't need (and I've been trying to tone down the number of mods I use) and it doesn't have a slope variant. Just two straight armoured pipe blocks would be all I need.

The ones in this mod would not be any different from the mod i would make. They would be identical, only some texture variations might occour. Why would I duplicate an already existing mod? (Keep in mind: I dont want to make a mod that only partially implements items.)
