Large diameter flange is a type of flange widely used and promoted in the mechanical industry, receiving high praise and favor from users. Large diameter flanges have a wide range of applications. The production process is divided into rolling and forging, and oversized ones can only be rolled. Common large-diameter flanges include flat welding flanges and butt welding flanges. The structure and scope of use of flat welding large-diameter flanges and butt welding large-diameter flanges are different, and the characteristics and advantages that large-diameter flanges can exhibit will also be different. Therefore, when using them, it is necessary to use them according to different scopes to ensure that the flanges play an important role. Large diameter flange and large diameter flat welding flange have poor rigidity and are suitable for situations with pressure p ≤ 4MPa; Welding flanges, also known as high neck flanges, have greater rigidity than large-diameter flanges, which are suitable for high-pressure and high-temperature applications. There are three types of flange sealing surfaces: flat sealing surfaces, suitable for situations with low pressure and non-toxic media; Concave convex sealing surface, suitable for situations with slightly higher pressure; Mortise and tenon sealing surface, suitable for flammable, explosive, toxic media and high-pressure environments.
Large diameter flange fittings with different properties have good product performance in different fields, and their effectiveness varies depending on the occasions and spaces they are suitable for. Main materials: 304L, 316L, Q16Mn Application industry: power, oil and gas, petrochemical, chemical, shipbuilding, heat supply, papermaking, metallurgy and other products features: beautiful appearance, smooth surface, acid and alkali resistance, corrosion resistance, strong texture performance
