A182 F304 slip on flange include flanges, bolt holes and sealing surfaces. The flange is a flat ring structure with an outer diameter larger than the outer diameter of the pipe connected to it. The bolt holes are evenly distributed on the flange and are used to install bolts to connect two flanges. The sealing surface is located on the inner side of the flange and contacts the end of the pipe. It is the key part to achieve the sealing function.

A182 F304 flange has good corrosion resistance, heat resistance and mechanical properties, and is suitable for general corrosive environments, such as ordinary food processing, domestic water treatment and other fields.

Advantages of Slip On Flange

  • The slip on flange method makes the slip on flange flange welding operation easy to carry out. At the construction site, welders do not need special welding skills or complex welding equipment to complete the welding connection between stainless steel slip on flange flange and pipeline. The installation speed is fast. Because its welding operation is simple and does not require precise matching operations like butt welding flanges, it can save a lot of time during pipeline installation.
  • Stainless steel material itself has good corrosion resistance. Stainless steel slip on flange flanges can effectively resist corrosion in various corrosive environments, such as humid industrial environments and medium transportation pipelines containing certain acid and alkali components.
  • Stainless steel slip on flange flanges can provide reliable sealing performance when properly installed and matched with suitable sealing gaskets. Its sealing surface is closely matched with the sealing gasket, and under the tightening action of the bolts, it can effectively prevent the leakage of liquid or gas in the pipeline.
