Stainless Steel Slip On Flange A stainless steel slip-on flange is a type of flange that is slipped over the end of a pipe and then welded in place. It has a circular bore and is designed to slide over the pipe, facilitating easy installation. The inner diameter of the flange matches the outer diameter of the pipe to which it is being connected. Slip-on flanges are commonly used in low-pressure and non-critical applications. What is a stainless steel flange used for? The Benefits and Uses of Stainless Steel Flanges | Texas Flange Stainless steel flanges are essential in industries like beverage, food, water, gas, and transport. It also provides several benefits, a few of these including: Corrosion and stain resistance: Stainless steel flanges are excellent in a wide range of atmospheric environments and many corrosive media.
