ANSI B16.5 FF 304 Cl150 Stainless Steel Threaded Flange

  When the gasket surface area is above the bolted line of the flange, the raised face flange is easily identified. It is compatible with a wide range of gaskets, from flat to semi-metallic and metallic types, either ring or full.

  The main scope of a raised face flange design is to concentrate the pressure of the two mating flanges on a small surface and increase the strength of the seal.

  The height of the raised face surface depends on the flange pressure level, for example, for pressure classes 150 and 300, the height is 1.6 mm or 1/12 inch, and for the 400 to 2500 level, the raised face height is about 6.4 mm, or 1/4 inch.

  Threaded flanges are used where it is difficult to weld or cannot be welded, such as threaded flanges used to protect the galvanized layer of pipes. In addition, It should not be used on pipes with repeated temperature fluctuations or above 260 ℃ and below -45℃ as well.
