Slip on Flange

The slip on flange is often manufactured with an inside diameter slightly larger than the outside diameter of the pipe. This enables the pipe to slip through it before welding. This steel flange can be securely firmed to the pipe by fillet welding at the top and bottom of the flange.

N-STEEL supplies slip on flange in various steel materials grades such as carbon steel slip on flange, alloy steel slip on flange, stainless steel slip on flange, etc. Our slip on pipe flange is perfect for low pressure applications. N-STEEL also has many different slip on pipe flanges in stock and ready to ship.
