This high-performance stainless steel flange is strictly manufactured in accordance with ANSI B16.5/16.47 standards, available in pressure ratings Class 150, Class 300 and Class 600, featuring a weld neck design, forged processing and threaded connection. It is crafted from premium stainless steel, integrating excellent corrosion resistance, high pressure-bearing capacity and structural stability, providing a reliable, leak-proof connection solution for industrial pipeline systems.
Adopting precision forging process, the flange has a dense internal structure, no internal defects, and superior tensile strength, yield strength and impact toughness, which can stably withstand the pressure requirements of Class 150, 300 and 600. The weld neck design ensures a smooth transition between the flange and pipeline, reducing stress concentration, enhancing structural integrity, and facilitating full penetration welding for a secure, permanent connection. The threaded design adds convenience to installation and disassembly, improving construction efficiency while ensuring tight sealing.
Made of high-quality stainless steel, the flange boasts excellent corrosion resistance, rust resistance and high-temperature resistance, adapting to various harsh industrial environments such as chemical, petrochemical and marine scenarios. It features precise dimensional accuracy, a smooth sealing surface (RF, RTJ optional) and good interchangeability, ensuring tight fit with pipeline nozzles and compatible with standard pipeline components.
Widely applied in petroleum, chemical, petrochemical, power station, water treatment and marine industrial pipeline systems, suitable for high-pressure, corrosive and high-temperature working conditions. It undergoes rigorous quality control throughout the production process, including forging quality inspection, chemical composition analysis, mechanical performance testing, pressure testing and dimensional detection, fully complying with ANSI B16.5/16.47 standards and international industrial requirements.
