Raised Face Flange
Raised Face Flange is one of the three major categories of flanges used in the industries. The other two types are flat face and ring type joint. The flanges are components with outward flared ends which can connect pipes and components together. The Stainless Steel Raised Face Flange is made up of stainless steel. The face or the outlet of the flange has a raised ring that can hold bolt holes.
Stainless Steel Raised Face Flanges
ANSI B16.5 Raised Face Flanges
Pn16 Raised Face Flange
This raised face is useful in getting extra grip and strength to the connection surface. Depending on the need of the application, the raised face can have different number of bolt holes. The Pn16 Raised Face Flange is one of the medium pressure grade flanges. The flanges can have pressure number ranging from PN6 through PN64 and the pressure classes ranging from class 150 through class 2500. There are different standards to govern the sizes an dimensions of the flanges. The API 6A RF Flange is made according to the American Petroleum Institute standard and is used in high temperature, high pressure applications. The material of the flanges is selected based on the material that is circulated through the pipes and the required corrosion resistance and strength of the flanges. The Carbon Steel Raised Face Flanges are preferred for high wear and tear applications. The carbon steel flanges also have higher toughness than the stainless steel flanges. But the SS Raised Face Flange is the most used with 304 and 316 austenitic stainless steel grades being the general materials.
