Flanges are also used on equipment inlets and outlets, such as reducer flanges, to connect two pieces of equipment. A flange connection or flange joint is a removable connection consisting of a flange, a gasket, and bolts, forming a combined sealing structure.

[0003] After searching, the announcement number CN221171220U discloses an anti-slip sealing flange, including a main body, a docking assembly provided on the top of the main body, the docking assembly including a second docking plate, the second docking plate fixedly connected to the top of the main body, a first docking plate fixedly installed on the top of the second docking plate, a docking fixing bolt threadedly connected to the top of the first docking plate, a connecting pipe fixedly connected to the top of the first docking plate, a through hole integrally formed inside the connecting pipe, and a sealing assembly provided between the first docking plate and the second docking plate. The flange is fixedly connected to the outside of the connecting pipe by a first anti-slip reinforcement plate, and the second anti-slip reinforcement plate is fixedly connected to the outside of the main body. The first anti-slip reinforcement plate and the second anti-slip reinforcement plate are reinforced by anti-slip fixing bolts to achieve mutual pulling, thereby achieving the purpose of increasing the limit of tension between the flanges and increasing the stability of the flanges.
