Steel-lined PTFE piping, commonly used in high-temperature and high-vacuum systems such as distillation. To ensure the steel-lined PTFE piping remains undamaged during operation, its anti-corrosion and insulation layer should possess the following mechanical strength:
1. Excellent wear resistance, preventing damage from external friction during construction.
2. Penetration must reach sufficient levels to ensure the coating can withstand concentrated loads.
3. Excellent bonding and adhesion with pipelines.
4. Possesses adequate impact resistance to prevent damage due to collisions during handling and soil pressure.
5. Excellent bend resistance; the manufacturer of steel-lined PTFE piping notes that this ensures the pipe does not get damaged during construction due to bending.
The anti-corrosion and insulation layer of the steel-lined PTFE pipe has the aforementioned mechanical strength, allowing it to be firmly bonded to the metallic surface, thus providing a tight seal against the external environment.
