Schedule 636 PVC

Hi everyone,

Does anyone know if schedule 636 PVC is aquarium safe. Its primary use is for venting flue gasses from furnaces and water tanks. I work with it so its free to me. Ive searched the internet purdy good to no avail. Ive used schedule 40 to plumb it but wanted to add a piece of 3" as a shelter.

Any way you can get a comparison chart for components between Sch 40 & Sch 636? Or material spec sheets on them?

When looking through the manufacturers PDF's I didn't see any comparisons.
