The use of PTFE elastic belts : Various enamel linings, glass linings, plastic linings, rubber linings, graphite linings and stainless steel, titanium steel towers, heat exchangers, reaction vessels and other flange surface seals.
Flange sealing of various pipes and fittings.
The appearance accuracy is poor, the uneven area is large, the shape is irregular, and the bolt tightening force is not easy to seal with the flange surface of a large-diameter device that is not suitable or is too large.
Strongly corrosive media and seals that cannot be minimally contaminated.
PTFE elastic belt
The PTFE elastic belt is made of pure polytetrafluoroethylene dispersion resin. It is made by pressing and high temperature stretching. It has a low coefficient of friction, chemical resistance, and good sealing. It can be used at temperatures of 250°C to +280°C, suitable for reactions. Kettles, steam generators and various special-shaped cans and barrels are sealed. The PTFE seal tape retains the excellent chemical resistance of PTFE, and it has excellent flexibility, compression recovery, excellent creep resistance and cold flow characteristics, and high tensile strength. strength.
This sealing tape can be easily affixed to the flange sealing surface, and there is almost no waste during use. The seal of the flange under medium and low pressure is a kind of economical and practical sealing material.
Application scope:
Maximum operating temperature: 330°C
Maximum use pressure: 6.3-20MPa
PH value: 0-14
