4 inch flare

4 inch flange is a commonly used connector in industrial piping systems, typically made of materials such as cast iron or stainless steel, with standard outer diameters and thicknesses, used to connect two sections of pipeline and ensure the tightness of fluid transmission. The nominal pressure range of 4 inch flanges is 0.25MPa to 2.5MPa, and its size and connection method follow relevant national standards, and are widely used in petroleum, chemical, plumbing and other industries, and can withstand high working pressure and temperature to ensure the stable operation of the system.
