A Reducing Slip-On Flange is a specially designed flange used to connect pipes of different diameters within a piping system while maintaining efficient flow and secure sealing. Unlike standard slip-on flanges, which are used for pipes of the same size, the reducing slip-on flange incorporates a smaller bore that allows it to connect a larger pipe to a smaller one without the need for separate reducers or adapters. It is slipped over the pipe and fillet welded on both the inner and outer sides, ensuring strong structural integrity and leak-free performance. This flange type is particularly suitable for low-pressure and non-critical applications where easy installation and alignment are required. Manufactured from durable materials such as carbon steel, stainless steel, and alloy steel, reducing slip-on flanges offer excellent resistance to corrosion and mechanical stress. They are commonly used in industries such as oil and gas, chemical processing, water treatment, and power generation to simplify pipeline transitions and optimize system performance.
