is this safe to use indoors if just wrapping around a steam heat pipe to reduce amount of heat it gives off? I'm not certain if fiberglass is appropriate or not

I want to use this product to cover the Heat Steam Pipe in my apartment in a tenament building which runs from floor to ceiling. Would the fiberglass melt if it heats up? Does Home depot offer any padding covers for these steam pipes. They become very hot to the touch.

Thanks

Is the insulation supposed to hew closely to the pipe? Or is there supposed to be space between the fiberglass and pipe?
