It not only ensures the sealing of the connecting part, prevents medium leakage, but also bears the pressure, temperature and various complex stress of the fluid in the pipeline. In some severe working conditions such as high-speed fluid and solid particle-containing medium, the erosion -resistant performance of the pipe plate flange is the key to ensure the long-term stable operation of the system.
[0003] However, the existing erosion -resistant pipe plate flange has obvious defects in practical application, and one of the prominent problems is that it cannot be quickly installed and disassembled.

When disassembling, the bolts also need to be loosened one by one in sequence, and the operation is cumbersome. Especially in some large equipment or space-limited places, due to the large size of the pipe plate flange, the surrounding operation space is narrow, which makes the installation and disassembly work more difficult, seriously affecting the maintenance efficiency and overhaul progress of the equipment. This not only leads to the extension of equipment downtime, increases the maintenance cost, but also may affect the normal operation of the whole production system due to the failure to maintain in time. Therefore, it is urgent to develop a pipe plate flange which can not only guarantee the erosion -resistant performance, but also realize quick installation and disassembly. UTILITY MODEL CONTENTS
