Home > Weld Neck Flanges (WNRF)
Weld neck flanges (WNRF) are important in piping systems and are valued for their robust construction and reliable operation. With a tapered centre for easy attachment to the pipe, they reduce stress and increase strength. These flanges are made of carbon steel, stainless steel, and steel alloys and offer top-notch corrosion resistance and mechanical properties. Widely used in industries such as oil and gas, petrochemical and electricity generation, they are tough, leak-free connections for critical applications demanding longevity and reliability. They provide reliability.

We offer These Weld Neck Flanges (WNRF) as per DIN, ISO, JIS or ANSI Standard.
Since Weld Neck Flanges (WNRF) have excellent mechanical qualities and are resistant to wear corrosion, and high temperatures, they are widely used in various industries. These flanges are widely used in the oil and gas, petrochemical, power generation, and aerospace industries. They play an important part in joining equipment, valves, and pipe systems. They are perfect for applications exposed to severe operating conditions, such as high temperatures, high pressures, and corrosive environments, because of their exceptional strength, toughness, and wear resistance.
Yes, weld neck flanges (WNRF) can be recycled after use. Typically constructed from recyclable materials such as carbon steel, stainless steel, and alloy steels, they can undergo melting and repurposing for new manufacturing processes. This recycling practice supports sustainability efforts and reduces environmental impact by minimizing waste.
