The design of some flanges is suited to reduce the tension or stress in a piping system. One type of flange is the weld neck or WN flanges. The design of these flanges includes a long neck or what is referred to as a high hub. Its long neck is the reason for many weld neck flanges manufacturers in India referring to it as a High hub flange. The neck of this component is tapered at the top, with the base having a larger diameter than its neck. Due to its tapered neck construction, many in the industry refer to them as tapered hub flanges.
The Alloy steel Weld Neck Flanges are suited to work in high pressure environments, especially since the stress that was initially accumulated at the base of the flange is evenly distributed in the neck. These flanges can be successfully employed in applications where the pressure applied is as high as 5,000 psi. Although using the appropriate material to produce the Wnrf Flange, like stainless steel or alloy steel is a must for both excellent performances as well as durability. The chemical composition coupled with the design of the component is what makes the Rtj Weld Neck Flange a good fit across applications that deal with both high or low temperatures. In applications where the temperatures range between low to sub-zero, it is challenging to find a design that permits excellent performance. In such conditions, the high, tapered hub, along with the appropriate grade of Stainless Steel Weld Neck Flange will yield good performance in both the corrosion resistance and mechanical properties. This remains one of the most easily identifiable flanges. And the Weld Neck Pipe Flanges is similar to an LWN flange, with the exception of the length of the neck, where it is longer in the latter.
