The ability of forged flanges to withstand pressure depends on their material and manufacturing standards. In general, forged flanges are made of high-strength metal materials (such as carbon steel, alloy steel, etc.), which can provide high pressure resistance. According to the international standard ASME B16.5, forged flanges have pressure ratings of 150, 300, 600, 900, 1500 and 2500 in pounds per square inch (PSI). Among them, the 150 forged flange has a pressure resistance of 150 PSI, and so on. It is worth noting that the pressure resistance of the forged flange is also related to its size, connection mode and operating temperature. In practical application, it is necessary to select the appropriate pressure grade of forged flange according to the specific engineering requirements and safety specifications to ensure the safe operation of the system. In addition, when designing and installing forged flanges, factors such as the nature of the medium inside the system, flow rate and working conditions must be considered to ensure that not only the pressure requirements are met, but also the reliability and safety of the system are maintained. Therefore, when selecting and using forged flanges, it is recommended to consult a professional engineer or refer to the relevant standards and specifications.
