Corrugated stainless steel tubing is like a straw made out of metal that can help move gas or liquids from one place to another. Imagine you want to drink water from a glass on one side of the room, but there is a big pile of toys in the way. You could use a straw to sip the water without having to move the toys out of the way. Just like a straw helps you move liquid from one place to another, corrugated stainless steel tubing helps move gas or liquids through pipes.
But why is it "corrugated" and "stainless steel"? Well, you know how some straws are straight and some have bends in them? The bends help the straw to bend and fold, making it easier to use. The corrugations in the stainless steel tubing work in the same way. They make it more flexible, so it can fit into spaces with tight corners or curves. Plus, using stainless steel makes it strong and resistant to rust or damage.
So if you ever need to move gas or liquid from one place to another, just imagine using a super strong straw that can bend and flex like magic. That's basically what corrugated stainless steel tubing is.
