When the Teflon surface becomes scratched, it can no longer provide the smooth, even surface necessary for proper sealing.
Scratches on the Teflon surface create gaps and uneven areas that allow fluid to leak through the seal. This leakage can result in reduced system efficiency, increased energy consumption, and potential contamination of the process fluid. Additionally, scratches can trap particles, leading to accelerated wear and further damage to the seal faces.
As the scratches deepen and spread, the seal’s ability to maintain a tight seal diminishes, leading to more significant leakage and eventual seal failure. This failure can cause unplanned downtime, increased maintenance costs, and potential safety hazards, especially in applications involving hazardous or flammable fluids.
