How do PTFE-lined products withstand pressure changes within a storage tank?
Release Time : 2025-01-22
PTFE-lined products are widely used in containers such as storage tanks because of their excellent corrosion resistance and non-stick properties. When the pressure in the tank changes, the PTFE lining needs to withstand the corresponding stress to ensure its integrity and performance.
The PTFE material itself has high strength and toughness and can withstand a certain amount of pressure. At the same time, it also has excellent chemical corrosion resistance and can remain stable in a variety of corrosive media.
Thickness selection: The thickness of the PTFE lining is usually determined according to the design pressure and use environment of the tank. Thicker linings can provide better pressure bearing capacity and corrosion resistance.
Strengthened structure: In some high-pressure tanks, PTFE-lined products may be used in combination with metal skeletons or reinforcement layers to improve the overall pressure bearing capacity.
Tight fit: During installation, the PTFE lining needs to fit tightly against the tank wall to avoid gaps and wrinkles. This can be achieved through professional installation techniques and equipment to ensure a good seal between the liner and the tank wall.
Preload application: During installation, the pressure tolerance of PTFE-lined products can be enhanced by applying appropriate preload. This helps ensure that the liner remains stable when the pressure in the tank increases.
Regular inspection and maintenance of the PTFE liner is also an important measure to ensure that it can withstand pressure changes in the tank. This includes checking the liner for cracks, peeling or wear, and repairing or replacing it in a timely manner.
PTFE-lined products can effectively withstand pressure changes in the tank through their excellent material properties, reasonable structural design, professional installation process and regular maintenance and inspection.
