The Raised Face flange is the most common type used in process plant applications, and is easily to identify. It is referred to as a raised face because the gasket surfaces are raised above the bolting circle face. This face type allows the use of a wide combination of gasket designs, including flat ring sheet types and metallic composites such as spiral wound and double jacketed types.
The purpose of a RF flange is to concentrate more pressure on a smaller gasket area and thereby increase the pressure containment capability of the joint. Diameter and height are in ASME B16.5 defined, by pressure class and diameter. Pressure rating of the flange determines the height of the raised face

Specifications covering the manufacture and dimensions of flanges:
ASTM SPECIFICATIONS
ASTM specifications regulate approved raw materials for which flanges can be made and specifications .
For stainless flanges are:
ASTM A.182 – Forged or Rolled Alloy Steel Pipe Flanges & Fittings for high temperature service.
ANSI AND MSS SPECIFICATIONS
The standards govern the dimensions and tolerances to which fitting are manufactured:
ANSI B. 16.5 – Steel Pipe Flanges and Flanged Fittings (1/2 inch to 24 inch nominal diameter)
MSS SP.6 – Flange Facings
MSS SP.25 – Marking of flanges
MSS SP.39 – Bolts and Nuts for Flanges
MSS SP.44 – Large Diameter Pipeline Flanges. (Over 24 inch dia)
API-605 – Large Diameter Flanges for petroleum Usage. (Over 24 inch dia)
The ASME Code is not a standard as such but section VIII provides the procedure for calculating dimensions For all pressurised vessels flanges. The following are not flange specifications but they influence the manufacture of forged steel flange
