Series B Flanges

Series B weld neck Flange, Series B Plate Flange, Series B slip on Flanges Supplier, ANSI B16.47 Series B Threaded Flanges, ANSI B16.47 Series B Class 300 Socket Weld Flanges, Series B Spectacle blind Flanges Manufacturer in India.

A Series B flange refers to a specific type of flange used in piping and plumbing systems. It is a type of raised face flange that conforms to the ASME B16.47 standard, which specifies dimensions and tolerances for flanges in a range of sizes and pressure classes.

The Series B flange is designed for use in applications that require higher pressure ratings than those covered by Series A flanges. It is typically used in large diameter piping systems and is available in sizes ranging from 26 inches to 60 inches.

Series B flanges are commonly used in the oil and gas, petrochemical, and power generation industries, among others. They are typically made from materials such as carbon steel, stainless steel, or alloy steel, depending on the specific application requirements.
