As A leading Manufacturers of Raised Face Flanges. We, Ample Alloys invest into resources, technologies and a workforce that is finest. These stainless steel raised face flanges serve the food processing, food and beverage, FMGC, and many more industries. A SS Raised Face Flange is the most frequently used flange-type in process plant applications. Monel RF flanges are easily identified, as the gasket surface of the flange is raised above the bolting circle face. As a result, they are called ‘raised’ face flanges.

Dimensions of Raised Face (RF) Flanges

The standards govern the dimensions and tolerances to which fitting are manufactured:

ANSI B. 16.5                       – Steel Pipe Flanges and Flanged Fittings (½ 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
