W150x22 is 6×15 for the imperial crowd.

I’m trying to visualize your plant in my head. Is this a small gas plant…..simple with some wells, a dehy, separator, pigging etc or is it bigger and more complex.

Are these supports basic t-post or basic 2 post single level racks low to the ground. Or are they multi-level over your head type racks? How wide are they approx.

For relatively low to the ground supports as I described above 2000mm wide or so, I think a W150x22 is ok. Overhead racks I would expect you would be a W200x24 up to a W250x89 depending on a whole bunch of things. I have to think your not designing a multi-level 20ft wide rack full of pipe though.
