Flange joints are a very common and widely used component in engineering design. It is an indispensable part for piping design, pipe fittings and valves, and is also a necessary component in equipment and equipment parts (such as manholes, sight glass liquid level gauges, etc.). In addition, flange joints are also often used in other professions such as industrial furnaces, thermal engineering, water supply and drainage, heating and ventilation, and automatic control. 2. Material: forged steel, WCB carbon steel, stainless steel, 316L, 316, 304L, 304, 321, chrome-molybdenum steel, chrome-molybdenum-vanadium steel, molybdenum-titanium, rubber lining, fluorine lining material. 3. Classification: flat welding flange, neck flange, butt welding flange, ring connection flange, socket flange, and blind plate, etc.Advantages: easy to obtain materials, simple to manufacture, low cost, and widely used.Stainless steel flanges have both mechanical design strength and relatively high elongation. Stainless steel flanges have excellent performance. Flanges refer to pipes, pipes and valves with holes in the connection, bolts make the two flanges tightly connected together, and there are gaskets on the flanges to seal. Due to its excellent performance, stainless steel flanges are widely used in many industries. Stainless steel metal building materials are one of the strongest materials. Stainless steel has excellent corrosion resistance and can permanently maintain the integrity of the design. It is easy to produce, process and manufacture, meeting the structural development requirements of architects and designers. All metals react with oxygen in the atmosphere and form an oxide film on the surface. For example, iron oxide is formed on ordinary carbon steel, the iron will continue to oxidize, and the corrosion will continue to expand, forming holes. On the other hand, stainless steel flanges will not happen, s
