What Is ASME B16.47?


ASME B16.47 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.

Large Diameter Flanges Use In Water Desalination Projects?

Large Diameter Flanges Use In Water Desalination Projects?

The use of ASME B16.47 Large Diameter Flanges can be seen in high volume applications like the water desalination projects. ANSI B16.47 Series B Reducing Flange refers to the composition and standard of the flange where the ASME B16.47 Flanges refers to the standard and type. ANSI B16.47 Reducing Flange are a variety of flanges with various compositions. Compositions vary such as in the asme b16.47 series b slip on flange made up of carbon steel and the asme b16.47 blind flange made up of nickel alloys.


Difference Between ASME B16.5 And ASME B16.47?

  • ASME B16.5 are components that are used to fit together two pipes or a pipe with other components in a system. They could either be connected by bolt and nut or by welding together. ANSI B16.5 belong to the standard B16.5. industrial flange have a category that can hold the classes 150 through 2500 and their diameter ranges from ¼ inches to 24 inches.

  • ASME B16.47 vary from nominal pipe sizes 26 inches to 60 inches. Large Diameter Flanges 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 can differ according to the material composition but they are usually heavier than the ASME B16.47 Series B Flanges.

Large Diameter Flanges ASME B16.47



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.
