The above describes the use of PTFE gasket on the use of methods and applications in the processing without adding any adhesive, nor deformation, with good flexibility, easy to install, with a unique design style.
Various types of gaskets in the case of improper or long-term use, there will be leakage or leakage of the situation occurred, a good understanding of these leaks can help us to make timely maintenance of the gasket to prevent leakage occur.
Teflon gasket leakage methods are: soaked leakage, interface leakage, PTFE Gasket, scattered leakage.
The first: soaking leakage: because the soft material of the material are mostly fiber, easily dipped by the media, specifically the role of pressure. Because of the capillary, the medium will penetrate the high pressure side to form a leak.
The second: interface leakage: the interface because the PTFE gasket is not enough pressure, flange joint surface brightness improper, flange deformation, etc. will be disclosed in the sealing interface. On the interface leakage, the use of soft material clamped in the flange surface can be prevented.
The third: PTFE Gasket: Teflon gasket in the sealing parts of the working conditions are relatively unruly, hot deformation, often by vibration, shock, improper device, tightening force is too large, repeated repeated applications, tightening deformation, internal stress Concentration, beyond the strength of fatigue and destruction, data aging, transformation, etc. will form a leak. This leakage has the greatest impact, the harm is also large, to enhance the preparedness.
Fourth: PTFE Gasket Dispersion Leakage: In the concentration of poor propulsion, the media through the sealing gap or sealing the material of the capillary material transfer occurred. Scatter is the result of molecular activity and is not one-way. In the gasket pressure difference is very small or vacuum, or sealing nitrogen, hydrogen and other leaky substances, and highly toxic, jet material to pay special attention to soak and disperse the two leaks.
