Purchase Stainless steel blind flange, CS Flange BLRF at Low Price

ASME B16.5 Blind Flange manufacturers in india belongs to a range of flanges that are ¼ inches to 24 inches in nominal bore sizes. Flanges are metallic products with collars that are used to fit pipes together. R.C. Metal Corporation is a leading supplier of Stainless steel blind flanges and other types. The blind flanges vary from all other types of flanges in their functionality. The Carbon steel blind flanges are made up of carbon steel and they block a pipe line or close it at the connection point. This is useful in high maintenance applications. The BLRF Flanges have raised faces and are fitted with bolts for maintenance services. Where the closure has to be permanent, the Flat face blind flanges are fitted with welding. There are different material grades, pressure ratings and classes of flanges required for different applications.


ASME B16.5 Blind Flange

ASME B16.5 Blind Flange

The PN16 Blind Flanges are one of the low pressure ratings. There are pressure ratings ranging from PN6 through PN64. The classes range up to class 1500 in this standard. The Raised face blind flanges are used in petrochemical industries, petroleum refineries, water management systems, waste water purification systems, pollution control systems and others. The ANSI b16.5 class 150 blind flanges belong to one of the lower classes with lower wall thicknesses. There are different materials used such as stainless steel, carbon steel, alloy steels and other high alloy materials that are used to make Class 300 Blind Flanges and other denotations.

There are applications such as chemical, pharmaceutical, food processing and sea water desalination plants that use the DIN 2527 PN10 blind flanges. The type of the flange can vary as screwed, threaded or forged. The forged flanges are most commonly used as they have high strength. The NPT Blind Flanges can also be used in high pressure applications such as the heat exchangers, boilers and condenser components. Some materials are corrosion resistant than the others so the selection of the material for the Grooved blind flanges also varies. The grooved flanges have grooves on them for better installation of pipes. Please contact us for more information on the Threaded Blind Flanges and other different types and prices.
