What is SS stainless steel pipe 1/2 inch?
Stainless steel pipe is steel pipe alloyed with chromium, and often nickel and molybdenum, so it resists rust and corrosion. Common grades are 304 and 316.
It keeps a clean, smooth bore. As a result, it suits food, dairy, beverage, pharmaceutical, chemical and water treatment lines, as well as architectural work.
