ASME B16.5 Blind Flange manufacturers in China 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. Hebei shengtian pipe-fitting group Co., ltd 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 ASME B16.5 Forged Carbon Steel CL300 Blind RF Flange 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.

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 ASME B16.5 class 300 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.
