Manufacturers of Stainless Steel RF Flange, PN16 Raised face flange in India.
ASME B16.5 raised face flange has a raised face for more connection strength. R.C. Metal Corporation is a leading supplier and manufacturer of the Stainless Steel RF Flange types. The stainless steel is the most used material for flanges. There are other materials such as high alloy steels, carbon steels, duplex steels and others as well. The PN16 raised face flange is one of the commonly used pressure number of the flanges. The pressure numbers can range from PN6 through PN64. The higher the number, the Class 150 rf flange Dimensions will also increase. The classes are a way of mentioning the relationship between the wall thickness and the diameter of the flange. These Refacing raised face flanges are made under the B16.5 standards and they range from ΒΌ inches to 24 inches in nominal bore sizes.
ASME B16.5 Raised Face Flange
There Cl 150 Rf Flanges is used with smaller size pipe lines. The applications of the raised face flanges can be seen in transmission lines in the petroleum and oil and gas industries. The PN40 raised face flanges have one of the highest pressure numbers. It can be used under high pressure applications such as boilers, heat exchangers, condensers and pressure vessels. The Stainless Steel raised face flanges are used in more general corrosive service applications with less corrosion prone applications but with high strength. There are different tables such as the Table E Raised face flanges which list out different mechanical properties and physical properties of the flanges.
There are also forged, welded, screwed and threaded flanges. The Threaded raised face flanges has threads on it for fixture with threaded pipes and other components. The threads on the flanges are usually female and they connect with male threaded components. The Weld neck raised face flanges is another type that has a weld neck on it. This weld neck allows for more welding surface and provides much better and stronger welding connection. Please contact us for more product details on the Socket weld raised face flanges and other types of flanges and price lists.
