Home > Threaded and Screwed Flanges
Threaded screwed flanges are essential components in piping systems, valued for their simple installation and adaptability. Internal threads can be readily connected to pipes or fittings without welding, which is ideal for scenarios where welding cannot be done. It delivers corrosion resistance and dependability and is manufactured from carbon steel, stainless steel, and steel alloys. Commonly employed in plumbing, HVAC, and water treatment applications, it ensures a secure, watertight connection, longevity, and adaptability.

Because Threaded and Screwed Flanges offer outstanding mechanical properties and resist wear, corrosion, and high temperatures, they are extensively used across numerous industries. These flanges see broad application in the oil and gas, petrochemical, power generation, and aerospace sectors. They serve a key role in connecting equipment, valves, and piping systems. Thanks to their remarkable strength, toughness, and resistance to wear, they are ideal for uses subjected to harsh operating conditions, including high temperatures, high pressures, and corrosive environments.
Yes, threaded and screwed flanges are recyclable once they have been used. Generally manufactured from recyclable materials such as carbon steel, stainless steel, and alloy steels, they can be melted and reused for fresh manufacturing processes, supporting sustainability initiatives and lessening environmental impact.
