Flange Faces Explained Flat Raised Etc Savree Access course here: wrtraining.org courses pipe fittings flanges valves visit our website: wrtraining.orgthis video is an introduction to the flang. Raised face flange has a small portion around the bore raised from the face. the gasket seat on this raised face. the height of the raised face depends on the flange pressure temperature rating, known as a flange class. for 150# & 300# height of the raised face is 1 16”, and above 300#, it is 1 4”. the inside bore circle type of gasket is.
What Are Piping Flanges Their Type Their Faces Their Rating By The flange face has an area beyond the normal (male) flange face. the other flange or mating flange has a matching recess (female) machined into the face. the female face is 3 16″ deep and the male face is 1 4″ high, both with a smooth finish. the outer diameter of the female face is used to locate and hold the gasket. Types of flanges. in this article, we review the 13 types of flanges for pipelines and piping systems (asme b16.5), divided into “standard” and “non standard” (or less common) types. large flange sizes, not examined here, are ruled by the asme b16.47 series a b specification. classification of asme flanges b16.5:b16.47 & special flanges. A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. it also provides easy access for cleaning, inspection or modification. flanges are usually welded or screwed. flanged joints are made by bolting together two flanges with a gasket between them to provide a seal. Threaded or screwed flange. threaded flanges are joined to pipes by screwing the pipe and are used on piping systems that prohibit direct welding on the pipe. usually, threaded flanges are used for galvanized piping. industrial threaded flanges are made in sizes up to 4 inches with various pressure ratings.

Marking (stamp) on the flange according to the requirements of the amse b16.5 pipe flanges and flanged fittings standard must include the size of the flange, flange rating class, the symbol “b16” or “b16.5”, material specification, and manufacturer’s name. 1: size of flange (nps), ex. 4″; see: piping tubing configurations. These piping flanges are supplied with a 0.06 inch raised face, which is included in the minimum flange thickness. the finished height of the face shall be less than the nominal pipe wall thickness. flanges in classes over 600 are supplied with a 0.25 inch raised face that is additional to the minimum flange thickness.
