Home > Long Weld Neck Flanges
Long Weld Neck Flanges is important in piping design, especially in high-pressure applications. Their extended necks allow for better flow and reduced stress, increasing connection strength. They are made of hard materials like carbon steel, stainless steel, alloy steel, etc. They are important in industries like oil, gas, petrochemicals, and power generation. These flanges offer exceptional mechanical properties and longevity, making them a reliable choice for demanding applications requiring durability and safety.
