During the use of steel lined PTFE pipelines, the following precautions should be taken to ensure their normal operation and extend their service life:
Media matching:
Before use, it should be ensured that the medium conveyed in the pipeline is compatible with the PTFE plastic lining material to avoid corrosion or damage to the lining caused by the medium.
Temperature control:
The working temperature of steel lined PTFE pipelines should be within their design range to avoid overheating operation that may cause aging or failure of the lining material.
Avoid sudden cooling and heating to prevent the pipeline from being damaged due to excessive stress caused by temperature changes.
Pressure limit:
The working pressure of the pipeline should be within its design pressure range to avoid overpressure operation that may cause pipeline rupture or leakage.
Installation and maintenance:
During the installation process, it should be ensured that the flange connections, welding, and other connections of the pipeline are well sealed to avoid leakage.
Regularly inspect the support and fixation of pipelines to ensure that they do not experience displacement or deformation.
When cleaning pipelines, appropriate cleaning agents and tools should be used to avoid damage to the lining.
Avoid collisions and scratches:
During transportation, installation, and use, it is necessary to avoid hitting or scratching the pipeline to prevent damage to the lining layer.
Electrostatic protection:
Steel lined PTFE pipelines may generate static electricity when transporting certain media, so corresponding static electricity protection measures should be taken, such as grounding.
Monitoring and recording:
Regularly monitor the operational status of pipelines, including temperature, pressure, flow rate, and other parameters, and record relevant data.
If any abnormal situation is found, the machine should be stopped in a timely manner for inspection and handling.
Long term storage:
If steel lined PTFE pipes need to be stored for a long time, they should be stored in a dry, ventilated place away from direct sunlight, and the condition of the pipes should be checked regularly.
Professional maintenance:
For steel lined PTFE pipelines with problems, maintenance and repair should be carried out by professionals to avoid non professionals from accidentally operating and exacerbating the problem.
Compliance with regulations:
When using steel lined PTFE pipelines, relevant safety regulations and operating procedures should be strictly followed to ensure the safety of personnel and equipment.
Following the above precautions can ensure the long-term stable operation of steel lined PTFE pipelines under harsh working conditions, improve production efficiency, and extend the service life of the pipelines.
