Problems solved by technology

[0002] Spring supports and hangers are mainly used for steam and water pipelines or boiler equipment in power plants, thermal displacement and equipment installations during operation. In the installation of supports and hangers, each part needs to be fixedly connected. In the past, positioning welding was used to The parts in the support and hanger are fixedly connected, but although this method is very strong, it cannot be disassembled at all, and it is inconvenient to maintain. The welded interface is easy to corrode and age, the service life is short, the cost is high, and the safety during welding is poor. A waste of resources; the welding method is abandoned in the prior art, and special connectors are used to effectively connect and fix the supports and hangers. At the same time, the long-term work safety of this connection method mainly depends on the working conditions of the contact surface and stress
[0003] At present, the connectors used in the installation of supports and hangers are particularly easy to corrode, easy to wear, and have insufficient strength due to working in an exposed environment for a long time. Therefore, it is necessary to develop a method that can overcome the above technical defects. The spring hanger connector has become a technical problem to be solved urgently by those skilled in the art
