For some reason the pipe Mk 2 - 4 is about 4 time the size on screen than it should be.
I've asked Dysoch for help and he has been very helpful, but since I'm the only one with this issue, we can't get this one kicked.
I've uninstalled Factorio, deleted the entire Factorio Roaming folder and re-installed it along with a fresh download of Dytech and still having the issue.
As you can see from the screenshot below, the pipe images in inventory is fine, it's just wen laying down the pipe MkII and greater that they blow up on screen, looking about four times as big as they should.
And it's only the straight not the underground pipe.
In the mean time, the pipes work, it's just the images looks horrible:

Here is some additional images and my discussion with Dysock:
