Product Overview

Key Features

Possessing rich domain expertise, we are efficiently meeting the needs of our clients by manufacturing and exporting a impeccable array of WNRF Flanges. Manufactured using premium grade materials and modern technology at our state of the art machining facility, these flanges are designed to transfer stress to the pipe. Owing to characteristics like sturdy construction, temperature resistance and high strength, our WNRF Flanges are used for high pressure applications in chemical and pharmaceutical industries. Being a quality centric organization, all our offered flanges are exported to various countries of Europe and the Middle East.

Further Details:

It is Weld Neck Raised Face (WNRF) Flange.

The weld neck flange derives its name from the neck portion of the flange that is welded to the end of a piping system. Weld Neck Flanges have a long tapered hub and are often used for high pressure applications. It is designed to transfer stress to the pipe, thereby reducing high stress concentrations at the base of the flange. Weld Neck flanges are costlier due to their design and engineering, and increased material

The three most common types of facings for weld neck flanges are raised face (most common), flat face, and ring type joint (RTJ). When ordering a weld neck flange, it is important to specify the schedule pipe is being used for. This is because the inside diameter of the flange will match the inside diameter of your pipe. The butt-weld joint this flange has with the pipe along with the tapered hub, makes this flange very resistant to dishing and a very sturdy connection. These flanges are ideal for extreme fluctuations of temperature and in environments where there may be a lot of bending and handling of the flanges.

These Flanges are available in the following range.
