Check B16.47 Series A Pipe Flanges Dimension And Weight Chart, ASME B16.47 Series B Reducing Flange At Lower Prices Compared To USA & UK, B16.47 Series B Class 150 Flange manufacturer in India.

ASME B16.47 Flange Dimensions vary from nominal pipe sizes 26 inches to 60 inches. ANSI B16.47 Blind Flange is a type which has a blind end. This is usually used in fluid flow systems where the pipe has to be closed. ASME B16.47 Series A Flange weight can differ according to the material composition but they are usually heavier than the ASME B16.47 Series B Flanges. The A series has less bolt holes and therefore is heavier than the B series which has much bolt holes. Stainless Steel ANSI B16.47 Flanges are used in larger piping systems with higher diameter pipes. ANSI B16.5 Class 150 Flange is a low pressure class specification. ANSI B16.47 Pipe Flanges are used in larger circulation systems.

The use of ASME B16.47 Flange can be seen in high volume applications like the water desalination projects. ASTM A182 SS ANSI B16.47 Flange refers to the composition and standard of the flange where the ANSI B16.47 Plate Flanges refers to the standard and type. Alloy Steel ANSI B16.47 Flanges are a variety of flanges with various compositions. Compositions vary such as in the Carbon Steel ANSI B16.47 Flange made up of carbon steel and the Nickel Alloy 200 ANSI B16.47 Flange made up of nickel alloys.


What is ASME B16.47 Flange?


ASME B16.47 Flange

Class 300 ANSI B16.47 Flanges belong to the 26 inches to 60 inches diameter range and the pressure class of 300. Hastelloy C22 ANSI B16.47 Flange are made up of this specific alloy. There are other alloy flanges such as the Duplex Steel ANSI B16.47 Flanges and the Inconel ANSI B16.47 Flanges which serve for different purposes and pressure classes like the DIN86029 PN10 ANSI B16.47 Flanges. The different compositions such as the Copper Nickel ANSI B16.47 Flanges and the Alloy 20 ANSI B16.47 Flanges have different specific usages. Their applications usually involve high volume and low pressure operations. Oil refineries and water pipelines are two major applications where the ANSI B16.47 Flange is used.

Copper Nickel ANSI B16.47 Series B Reducing Flange fall under the category of large diameter steel pipe flanges, of sizes NPS 26 to NPS 60. In their design, Stainless Steel B16.47 Reducing Flange are stronger, bulkier and thicker, as compared with Carbon Steel Flange B16.47 Series A and because of this Ductile Iron B16.47 Series A Flange perform extremely well under loads of huge pressure, in the fields of heavy-duty engineering and load handling equipment.
