A105 B16.5 Raised Face Welding Neck Flange WNRF
The ASTM A105 standard refers to carbon steel flanges that are forged for high-temperature applications in a pressure system. We are one of the top manufacturers of ASTM A105 Carbon Steel Weld Neck Flanges in India, and these flanges are in good demand due to their usability. The ASME SA 105 WNRF Flange is ideal for severe and critical environments. Our CS A105 Weld Neck Flanges are known for their excellent tensile and material strength. We can customize them as per the dimensional requirements of our client. We have a wide range of ASME SA 105 Long Weld Neck Flange available in different sizes, lengths, and shapes, and we supply them to the client as per the order specifications.
A weld neck flange, also called a tapered hub flange or high-hub flange, is a kind of flange that can relocate stress to the pipes, ensuring a decrease in high-stress concentration at the bottom of the flange. There are two welding neck flanges designs - the first type is used with wipes while the second, longer type cannot be used with pipes but with a process plant. The weld neck flange comprises of a round fitting that extends beyond the rim of the circumference. These flanges, typically manufactured from forging, are actually welded to pipes.
Weld neck flange dimensions are covered in ASME B16.5 - which covers Pipe Flanges and Flanged Fittings for size NPS ½" to 24" for above NPS 26" to 60" it should be as per ASME B16.47.
During a dimensional inspection of weld neck flange, you should check for
- Outer & Inner Diameter of body
- Bolt Circle & Bolt hole Diameter
- the thickness of weld end
- Length of the Hub and
- Straightness and alignment of the bolt hole
