ASME B16.47 Flange

Refer ANSI B16.47 Series B Class 75, 150, 300, 400, 600, 900 Slip On Flange dimensions at a gance

What is ASME B16.47 Flange?
The ASME B16.47 is the standard for steel flanges having a large diameter. They are available within the size range of NPS 26 through NPS 60. They are further classified into ASME B16.47 Series A and ASME B16.47 Flange Series B. The specification of the flanges covers materials, dimensions, markings, tolerances, pressure ratings, and testing. They are also available in different rating class designations, from 75 to 900. They are also available in different pressure ratings from class 150 through class 900.
The ASME B16.47 Flange can be either weld neck flange or blind flange. The weld neck ASME B16.47 Flange is made by forging or casting, whereas the blind ASME B16.47 Flange is made from forging, casting, or plates. They are made of different materials and their characteristics might vary accordingly. Forged ASME B16.47 Series A or Series B Flanges should be manufactured in a single piece according to the material specification which is applicable.

Where ASME B16.47 Flange are used?
The ASME B16.47 Flanges are used in a wide range of industries like oil and gas pipeline, chemical, plumbing, water supply system, food processing, power plants, and many more.

Asme B16 47 Series A Vs Series B
The main differences between Asme B16 47 Series A and Series B are:

• The series A is referred to as MSS SP 44 flange whereas the series B is also known as API 605 flange.
• The series A flanges are thicker than series B, even if they are of the same size and pressure rating.
• The series A flanges are capable of withstanding more external loading compared to the series B flanges.
• The series B flanges need smaller but more fasteners compared to series A.
• Series B comes with a smaller bolt circle diameter and hence they have smaller flange movements post installation.
• Only series A flange has a Ring Type Joint flange from pressure class 600 to 900 of the given standard.
• Series B flanges are more affordable than the series A flanges.
• The series A flanges are primarily used in new pipelines or equipment, whereas the series B flanges are most often used in replacements and non-critical piping jobs.

Difference Between ASME B16.47 Class 300 Flange Vs ASME B16.47 Class 600 Flange
The primary difference between ASME B16.47 Class 300 Flange and ASME B16.47 Class 600 Flange is in their pressure classes. The class 600 flange is capable of withstanding more pressure at an increasing temperature compared to the class 300 flange. This means that the class 600 flange is stronger than class 300 flange, and can be used in applications that have higher pressure.

Advantages of ANSI B16.47 flange
The advantages of ANSI B16.47 flange are:

• They can be used for large diameter pipes within the size of NPS 26 through NPS 60.
• They are available in different pressure ratings from class 150 through class 900.
• They are made of different materials and their characteristics might vary accordingly, and hence they can be used in a wide range of applications.
• They are available in series A and series B, which are used in both new pipelines as well as in replacement piping systems.
