Texturing pipes properly is a pain, but it can be done.
In a sinch you have to use the UV wrapper.
So make a 8 sided cylinder 0.50 radius. Go into texture mode then select one of the faces on it, get one of the pipe textures. (mtl_chromepipe02.tga is a good one.) Then basically divide the number of faces (8 for instance) by what ever the texture size is, so lets say 256 x 256 so just 256/8 = 32 so select one of the faces on the cylinder then in the uv wrapper select the nodes for the face. Then hit the grid snap button and bring the nodes to an imaginary grid. Then line them up vertically.. 'ok shoot' let me make a youtube video about this, its too complicated to describe easily lol sorry give me a day.

Ah yes, thanks for making that video it shows us how to texture straight
pipes but what about texturing pipes that have one bend or more than
one bend going around corners?
I know the bend function starts all going corrupt and start splitting faces
after making a couple of bends in each pipe.
So it looks like you can only bend 1 section of pipe at a time and looks like each section that you bend has to be saved separately as a group.
But I don't know how to uvwrap the extrusions (to bend the pipe).
But the tricky thing is being able to uvwrap it so when the pipe
is then bent the texture will look right.
I suppose then we just load each pipe section one by one as a group back into the editor then maybe you have to use carve or snap to grip to join the pipes together because fuse just causes the brush being fused to lose all its textures.
