It's called 40 pound, but I don't know what that means. Zip ties might work for attaching. Don't buy the cheap Walmart ones. They strip out.

Do you mean Schedule 40? That relates to the wall thickness of the pipe, not weight. A higher number is thicker, i.e. Schedule 80, and is stronger. Partly in older standards that also referred to the nominal lifetime (years) of the pipe in ordinary service.
