Where are the most important locations protected by disassembly joints?
A disassembly joint is a piece of equipment used in a piping system whose main function is to accelerate and slow down the flow of water in the piping system through the expansion and contraction movement of the pipe. Due to its importance in the piping system, protecting the disassembly joint becomes a critical issue.
 
Generally speaking, the location where disassembly joints should be protected is at the weld of the pipe, because the weld is a weak point of the disassembly joint, which is easily affected by the external environment, such as temperature and pressure, resulting in a decrease in the sealing performance of the disassembly joint, which in turn leads to leakage of the pipe.
Secondly, disassembly joints should also be protected at the inlet and outlet of the pipeline because these two locations are where the water flow is generated and if the disassembly joint is damaged at these two locations, it may lead to water leakage and thus affect the operation of the pipeline. In addition, the protection of disassembly joints in piping systems is similar to the protection of other equipment. For example, when installing disassembly joints, it is necessary to follow the relevant standards and specifications to ensure the sealing performance of disassembly joints; when using disassembly joints, it is also necessary to regularly check and maintain them to ensure their normal operation.
Disassembly joints play an important role in piping systems, and protecting them is the key to their normal operation. Therefore, when using disassembly joints, it is necessary to pay attention to their protection location and take corresponding protection methods and measures.
