Product parameters

Product installation precautions

1. When assembling PTFE-lined equipment, special tools should be used, and the direction of the operating components should be paid attention to to avoid damage to the bearings and seals
2. During the installation process, avoid dumping the PTFE-lined equipment or causing collisions, so as not to affect the service life of the equipment
3. When tightening the bolts, the operation should be carried out in strict accordance with the tightening torque standard to avoid the bolts being too tight or too loose
4. When installing PTFE-lined equipment and pipelines, care should be taken to prevent impurities from entering the equipment, so as not to affect the sealing of the equipment
5. During the installation process, the pipes and interfaces should be properly connected according to the requirements of the equipment, and the opening and closing directions of the check valve and gate valve should be ensured
6. After the installation is completed, the tightness test should be carried out to ensure that the equipment is leak-free, and the secondary grouting and fastening should be carried out according to the requirements

Inspection and maintenance of products after installation

1. After the installation is completed, a comprehensive inspection of the PTFE-lined equipment should be carried out, and a trial operation should be carried out before the equipment is determined to be working normally
2. Before the equipment is put into use, the equipment and pipelines should be carefully cleaned to ensure that there are no impurities and impurities
3. For PTFE-lined equipment and pipelines that are not used for a long time, anti-corrosion treatment and regular inspection should be carried out to ensure the long-term use of the equipment
