ASME B 16.47 Series B WNRF Flanges
ASME B 16.47 Series B WNRF Flanges Manufacture
There are different types of flanges such as the ASME B 16.47 Series B WNRF Flanges which has a socket weld on it.
This socket allows for maximum grip and holding of the pipes, but the socket weld flanges are more common in smaller pipes than larger pipes.
The ASME B 16.47 Series B WNRF Flanges have the highest-pressure ratings and can be used in pressure vessels, heat exchanger, boiler and in the oil and gas industries.
The ASME B16.47 series B Welding Neck Flanges can also come in different manufacturing types such as forged, screwed or threaded types.
The blind flanges can come in different classes such the ASME B 16.47 Series B WNRF Flanges and in different material makes.
We are one of leading ASME B 16.47 Series B WNRF Flanges Manufacture in Kolkata, West Bengal, Bihar, Odisha, and Jharkhand.
Indications.
- OD = Diameter at Weld Bevel
- D = Overall Diameter of Flange
- B (WNF) = Minimum Thickness of Welding Neck Flange
- B (BLF) = Minimum Thickness of Blind Flange
- H = Length thru Hub
- A = Diameter at Base of Hub
- G = Outside Diameter of Raised Face
- K = Bolt Circle Diameter
- L = Diameter of Bolt Holes
General notes.
- Dimensions are in millimeters unless otherwise indicated.
- For dimensions “B” and “H” click IMPORTANT.
Blind flanges ASME B16.47 series A flanges (≥ NPS 26) are MSS SP-44 flanges.
- ASME has incorporated the MSS-SP44 specification into B16.47 Series A and the API 605 Specification into B16.47 series B.
These specifications include only Welding Neck and Blind Flanges. - Dimensions for Classes 400, 600 and 900 NPS 38 and larger for Series B flanges are the same as for the Series A flanges.
- The length of the Stud Bolt does not include the height of the chamfers (points).
The stainless-steel flanges are the most used but there are other material made flanges as well. The ASME B 16.47 Series B WNRF Flanges is of the lowest pressure rating and it can come in copper, brass, high alloys and other materials depending on the applications’ mechanical, physical and chemical requirements.
As a leading manufacturer, we make the ASME B 16.47 Series B WNRF Flanges and others in high quality. Please feel free to contact us for more information on the different flanges such as the ASME B 16.47 Series B WNRF Flanges and their prices.
