<p><b>Cupro Nickel Long Weld Neck Flanges</b> are specially designed with an extended tapered hub that provides superior strength and smooth stress distribution in high-pressure and high-temperature piping systems. Manufactured from copper-nickel alloys such as <i>90/10 and 70/30 grades</i>, these flanges offer exceptional resistance to seawater corrosion, erosion, and harsh industrial environments. The long neck design helps reduce turbulence and ensures a smooth flow transition, making them ideal for critical applications in offshore platforms, marine engineering, desalination plants, and power generation industries.</p><p><br>In addition to their excellent corrosion resistance, Cupro Nickel Long Weld Neck Flanges deliver strong mechanical performance and long-term reliability in demanding operating conditions. Their butt-welded connection provides a secure, leak-proof joint that enhances the structural integrity of the piping system. These <b>flanges</b> are available in various sizes, pressure classes, and international standards to meet diverse project requirements. Due to their durability, efficiency, and ability to handle extreme environments, Cupro Nickel Long Weld Neck Flanges are widely preferred for high-performance industrial and marine applications.</p><p><br></p><div>

It is manufactured in 90/10 and 70/30 copper-nickel and is highly resistant to corrosion, biofouling and erosion in seawater. The long tapered hub is designed to provide better stress distribution and greater structural strength and is thus applicable in the applications of critical offshore, shipbuilding, condenser and desalination. The flanges have the ability to work at temperatures between --20°C to 300°C with a life span of up to 10 years in the marine and industrial environment where it is used without leakage.</span></div>
