Whether stainless steel flanges require jumper wires mainly depends on the specific application scenario and safety requirements.
In most cases, stainless steel flanges require bridging. Crossover is a method of connecting pipelines, allowing fittings in different pipelines to be connected, thereby maintaining the continuity of gases and liquids. Stainless steel flanges, as important tools for connecting pipelines and equipment, usually require bridging to prevent pressure loss accidents.
However, whether cross connection is necessary also depends on the specific application scenario. For example, on pipelines that transport flammable and explosive materials, regardless of whether the gasket is insulated or not, static jumper wires are required for flanges and valves for safety reasons. In addition, according to the "Lightning Safety Code for Petroleum and Petroleum Facilities", metal jumper wires should be installed at the connections of flanges and valves in oil pipelines. When flanges are connected with more than 5 bolts, metal wire jumper wires are not necessary, but an electrical circuit must be formed.
Therefore, whether stainless steel flanges need to be bridged depends on specific application scenarios and safety requirements. In flammable and explosive environments, bridging is necessary; Under certain specific conditions, such as when flanges are connected with more than 5 bolts, it is not necessary to cross connect but the electrical circuit must be ensured.
