►Product Description
A weld neck flange is characterized by its extended tapered hub, which seamlessly integrates with the pipe or fitting through butt welding. In this process, the pipe end is fitted into the flange and welded along its perimeter, creating a durable, leak-resistant connection. The hub's design not only strengthens the flange but also minimizes the risk of deformation or damage. Predominantly employed in demanding sectors such as petrochemical, oil and gas, and power generation, weld neck flanges are manufactured from various materials including carbon steel, stainless steel, and alloy steel to cater to a wide range of operational requirements.
