Precautions for connection of PTFE-lined flexible rubber joints

The PTFE-lined flexible rubber joint is a connection component that can withstand the bending and twisting between pipeline systems. This connection component is suitable for pipeline systems in the chemical, pharmaceutical, food and electronic industries, and has good sealing and corrosion resistance. In the installation and maintenance of this connection component, some regulations and techniques need to be paid attention to to ensure the stability of the connection component and the normal operation of the system. The following will introduce the precautions for the connection of the PTFE-lined flexible rubber joint.

• Preparation before installation
• Confirm that the model and specification of the PTFE-lined flexible rubber joint match the pipeline system. 2. Check whether the surface of the pipeline system is flat and smooth, and whether the flange surface and the surface of the PTFE-lined flexible rubber joint are damaged or have other defects. 3. Communicate and coordinate work to ensure normal operation, and check the preparation of the required tools.
• Installation steps
• Clean the pipeline connection port and both ends of the flexible rubber joint, and apply an appropriate amount of lubricant and grease to prevent the rubber parts from drying and hardening. 2. Align one end of the PTFE-lined flexible rubber joint with the pipeline interface, and the other end with the pipeline interface connected to it, and tighten the flange bolts one by one. 3. After the two ends are connected to the pipeline, adjust the position and angle of the PTFE-lined flexible rubber joint according to the working pressure requirements to ensure that it can withstand the twisting and deflection of the pipeline. 4. Tighten the flange bolts one by one, and follow a certain rule and sequence to ensure uniform tightening.
• Precautions when using
• Do not exceed the twisting angle and load-bearing capacity of the PTFE-lined flexible rubber joint. 2. Before use, carefully check the condition of the pipeline and the PTFE-lined flexible rubber joint to ensure that there is no damage or aging. 3. During operation, the tightness of the joint and the flange seal should be checked regularly. If there is insufficient tightening and water leakage, it should be handled in time. 4. Avoid the influence of harmful environments and media such as high temperature and strong acids and alkalis during use to ensure the service life of the PTFE-lined flexible rubber joint.
  In summary, the PTFE-lined flexible rubber joint is of great significance to the smooth operation and stability of the pipeline system. When using and installing, it is necessary to operate in accordance with the corresponding specifications and precautions to ensure the stability and sealing of the connecting parts and ensure the normal operation of the system. At the same time, pay attention to the maintenance and replacement periodicity of the joint during use to ensure its long-lasting and stable service performance.
