Pentagon Steel India is a leading manufacturer, supplier, and exporter of long neck flanges (LWNRF) in India, offering a variety of materials, including stainless steel (304/304L, 310/310S, 316/316L, 317/317L, 321/321H, 347/347H, and 446). Long-neck flanges are designed for high-pressure applications and provide excellent strength and stability in pipeline systems. These flanges feature an extended neck, which gradually increases in diameter from the pipe to the flange, allowing for a smooth transition of stress across the pipeline, reducing the risk of cracking or failure.

The long neck provides reinforcement, making these flanges particularly well-suited for severe service conditions, such as those found in chemical plants, oil refineries, and power generation facilities. Their design ensures excellent performance in high temperature and high pressure environments, making them an ideal choice for critical applications.

Long Neck Flanges are often used in systems that require repeated disassembly, as their robust design ensures long-term durability and resistance to wear and corrosion. The extended neck also makes them a preferred choice for applications requiring precise alignment and minimal movement under pressure. 

Pentagon Steel India offers long neck flanges in a wide range of grades and materials to cater to the specific needs of industries around the world. With a focus on quality, precision, and durability, Pentagon Steel India delivers flanges that meet stringent international standards, ensuring reliable performance in demanding industrial environments.
