When running alongside a pipe that is attached to a boiler, the character is graphically displayed as beneath the boiler pipe input but above the pipe.
You aren't able to walk through any pipes, it is just a graphics issue.
To reproduce:
Place down pipes connected to a boiler with the steam output facing down. The graphics issue only appears to happen with that orientation. The pipes also must be either straight or coming in from above.
Once the pipes and boilers are placed down, walk towards the boiler while pressed up against the pipes (you can get the weird graphics by walking from other directions, but walking along the pipes most reliably reproduces it)
