Check Raised Face Serrated Finish and ASME B16.5 Flange Facing Finish Online

Every flange produced has a different face, which is dependent on the application it is used for. The surface area that hosts the gasket is what is known as a flange face. Today, with metals being used across all industrial sectors, there are many different Flange Facing Type & Finish. Some of the more common flange face types include tongue and groove, flat face, raised face, lap joint, Ring joint flange, and lastly, Male and female flange.

Flange Facing Type & Finish

These faces are produced with four different finishes. The four Types Of Flange Face Finish include spirally serrated, concentric serrated, stock finish, and a smooth finish. The main purpose of using finishes on the surface of a flange is to determine the level at which a gasket would be able to secure an impervious seal. For instance, a concentric Flange Serrated Finish has an evenly spaced out groove angled at 90° with the use of a specific tool. This finish is specifically designed to meet the requirements of a piping system that ferries across fluids of very low density. Similar to concentric serrated flanges, a spiral Raised Face Serrated Finish uses a tool that marks a groove angled at 45°. On the other hand, a smooth finish flange is where the surface, on visual examinations displays no marking. Hence, this is a Flange Finish Types that are used in a combination of gaskets with metal facings. The metal facings would include a double jacketed, corrugated metal or a flat steel facing. The mating of smooth surfaces creates a seal. Though it is important to note that the smoothness of the opposite face of the mating material will determine the integrity of the seal. The smoother the Flat Face Flange Surface Finish, the better is the formation of the seal between the mating surface and the flange.

Flange Face Finish

Best price and genuine material, manufacturer of Raised Face Serrated Finish and Stainless Steel Flat Face Flange Surface Finish in Mumbai, India
  • Cold Water - It has a mirror like finish. This is made with a wide tool at a high speed which gives a finished surface much like a ground surface. When a surface has this type of finish it is normally used metal to metal, not with a gasket. It is seldom used in the oil, chemical or related industries.
  • Concentric Serrated - A 90 degree inclined angle tool is used to make the grove. It makes a grove 1/64" deep and 1/32" apart in a concentric circle.
  • Smooth - This can be made with several different types of tool shapes. No tool markings will appear to the naked eye on the surface. The roughness of the finish is from 125-250 microinch.
  • Spiral Serrated - This is similar to a stock finish but the difference between them is the way the grove is made. A 90 degree inclined angle tool is used to make the grove. It makes a grove 1/64" deep and the feed is 1/32".
  • Stock - The surface is created by a continuous spiral groove. The roughness of the finish is from 125 to 500 microinches and is cut with a tool with an approximately 0.06 inches or larger radius.
