Carbon Steel WNRF Flange Manufacturers and Suppliers:
A Carbon Steel Weld Neck Flange is a type of flange that is commonly used in piping systems to connect pipes and valves together. It has a long tapered hub and a smooth, rounded transition from the flange face to the pipe bore, which makes it easy to weld onto the pipe.
Carbon steel is a popular choice for weld neck flanges because of its strength and durability, and because it is a cost-effective material. It is often used in high-pressure and high-temperature applications, where its strength and resistance to corrosion are important factors.

Carbon steel Weld neck flanges are designed to transfer stresses to the pipe, which makes them suitable for use in high-stress applications. Carbon steel Weld neck flanges are also ideal for use in applications where the pipe needs to be dismantled frequently, as they allow for easy disassembly and reassembly of the pipe.
Overall, Carbon Steel Weld Neck Flanges are a reliable and cost-effective solution for connecting pipes and valves in piping systems.
We have the ready inventory of Carbon Steel Weld Neck Flange in the different size ranges of 1 Inch, 2 Inch, 3 Inch, 4 Inch, 5 Inch, 6 Inch, 7 Inch, 8 Inch Carbon Steel WNRF Flanges.
