What is ASME B16.47 Flange?
The specification for steel flanges with a large diameter is ASME B16.47. There are sizes NPS 26 through NPS 60 available for them. They are further divided into ASME B16.47 Flange Series B and Series A. Materials, dimensions, markings, tolerances, pressure ratings, and testing are all covered in the flanges' specification. Additionally, they come in several rating class designations ranging from 75 to 900. Additionally, they come in pressure ratings ranging from class 150 to class 900.
The ASME B16.47 Flange can either be a blind flange or a weld neck flange. Forging or casting are used to create the weld neck ASME B16.47 Flange, whereas plates, casting, or forging are used to create the blind ASME B16.47 Flange. They are manufactured of various materials, and as a result, their qualities may differ. The corresponding material specification should be followed when manufacturing forged ASME B16.47 Series A or Series B flanges in a single piece.

Where ASME B16.47 Flange are used?
Numerous industries, including those in the oil and gas pipeline, chemical, plumbing, water supply system, food processing, power plants, and others require ASME B16.47 flanges.

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.
