Stainless steel flanges connect with pipe and fittings to form a piping system that delivers air, water, natural gas, oil, and steam in plumbing applications and food and dairy processing. Flanges provide easy access for cleaning, inspection, and modification. Flange types including blind, butt weld, lap joint, slip-on, socket weld, and threaded, are available in a variety of sizes and shapes. Stainless steel is durable, resists corrosion from caustic chemicals, corrosive fluids, oils, and gases, and withstands pressure and high temperatures.
