Stainless steel is durable, resists corrosion from caustic chemicals, corrosive fluids, oils, and gases, and withstands pressure and high temperatures. Type 304 stainless steel, a chromium-nickel material, resists corrosion caused by water, heat, saltwater, acids, minerals, and peaty soils. Type 316 stainless steel has a higher nickel content than 304 stainless, plus molybdenum, for even greater corrosion resistance. Stainless steel pipe transports air, water, natural gas, oil, and steam in plumbing applications and food and dairy processing. Stainless steel fittings connect to pipe and are commonly fitted with quick-connect clamps for easy removal and cleaning. Stainless steel flanges connect with pipe and fittings to form a piping system. Flanges provide easy access for cleaning, inspection, and modification. Stainless pipe, fittings, and flanges come in a variety of sizes and shapes.
