Industrial-Grade Welding Flanges Protective Flange Covers

The appearance of a solid round plate, peripheral bolt holes, no welding flange neck, sealing surface in various forms, flat, convex, concave and convex surface, tongue and groove surface and ring connection surface. Materials include carbon steel, stainless steel, alloy steel, copper, aluminum, mainly play the role of sealing, isolation and cut off to prevent leakage or overflow of the medium in the pipeline, used for equipment testing, test pressure, etc.. Its advantage is that it can be disassembled at any time, easy to connect and use, can withstand greater pressure, high mechanical strength, strong sealing, good chemical stability. Widely used in petroleum, chemical, shipbuilding, pharmaceutical, metallurgy, machinery, food and other industries . Flange cover can isolate different areas or equipments in pipeline system. In the complex and changing scenarios of industrial production process, when a certain equipment needs to be overhauled, maintained or replaced, just install the flange cover, which can quickly cut off the connection between the equipment and the pipeline network, avoiding the interference of other parts of the pipeline that are running, and at the same time, preventing impurities from entering into the pipeline in the process of maintenance.
