ASME B16.5 RF Flange and Stainless Steel Large Raised Face Flange manufacturer in India

Aside from spectacle flanges, another easily identifiable connecting device is the raised face flange. As the name suggests, the gasket of the said flange is raised such that it is placed above the bolting circle. The use of forged Raised Face Flanges is commonly seen in machines and in valves. A benefit of using such a design is that there are several combinations of gaskets that could be used together. One of the most utilized combinations is the spiral wound, which is followed by both flat ring sheets as well as a double jacketed type.

Raised Face Flanges

The purpose of using Alloy steel Raised Face Blind Flange is to intensify or increase the concentration of pressure in a given area of a gasket. And because the pressure applied on the gasket has become more focussed, the joint’s pressure containment capacity witnesses an increase. Similar to other flanges, the bolt holes are drilled on the outer ring of the Pn16 Raised Face Flanges, permitting better fastening to piping systems. This flange may be used in the creation of a tighter seal, and thus, proving to be useful across critical applications. Though the alloy used in the manufacture of Smooth Raised Face Flanges for such applications needs to exhibit properties like high mechanical strength, good to excellent resistance to corrosion, and better durability. Often such projects may use alloys like stainless steel, alloy steel, or even carbon steel. While a Carbon Steel Large Raised Face Flange is considered to be economically feasible, it lacks corrosion resistance properties. Yet its use is prominent across the oil and gas industry because they exhibit very high hardness and toughness at a fraction of the cost of conventional alloys. The combination of heat treatment along with the appropriate standard (ASME B16.5) also helps in increasing the working lifespan of the Stainless Steel Raised Face Flanges.
