PTFE Seals Due to the different forms of flanges

Polytetrafluoroethylene gasket - PTFE is the main raw material, by adding special substances after processing from the PTFE gasket.

      Due to the different form of flange (flat flange FF, convex flange RF, concave and convex flange MFM, etc.), need to seal the different media (liquid, gas, etc.), in order to achieve the best sealing effect, select the appropriate The thickness of the Teflon gasket corresponds to the form of the flange.

      For example: sealed liquid medium, when the working conditions for the plane flange (FF), the temperature is -100 ℃ ~ + 150 ℃, the choice of 3 mm thick PTFE gasket the best effect; when the case for the convex flange (RF type), the temperature is -100 ℃ ~ + 170 ℃, then select the 1.5 mm thick PTFE gasket effect is the best.

      Sealing gas medium, the use of PTFE gasket thickness <1.5mm, the temperature must be less than 100 ℃, the best results. If the pressure is less than 0.2Mpa, can be used in 3mm polytetrafluoroethylene gasket.

How does polytetrafluoroethylene gasket meet market demand?

      Poly PTFE gasket has a very good lubrication effect, in the solid material friction system minimum. What is the outstanding advantages of poly-PTFE gasket in the end it also can meet the different needs of users. Here by Shuo Feng machinery for you to do a detailed introduction.

      Polytetrafluoroethylene gasket weather resistance, polytetrafluoroethylene in the plastic in the best aging life. PTFE gasket itself has a high resistance to erosion, physical function is not chaos, high and low temperature resistance, the achievements of its good sealing function, in the petroleum, chemical, pharmaceutical, power, steel industry has a wide range of applications.

      Polytetrafluoroethylene gaskets are not adherent, polytetrafluoroethylene has the smallest surface tension in solid materials and does not adhere to any substance.

      Polytetrafluoroethylene gasket low temperature, with good mechanical toughness; even if the temperature dropped to -196 ℃, can also maintain a 5% elongation. Commonly used in the temperature, pressure alternating intense sealing parts, is the pipeline, valves, pumps, heat exchangers, towers, manholes, hand holes and other flange connection of the static sealing components.

      Polytetrafluoroethylene gasket itself has a high resistance to erosion, physical function is not chaos, high and low temperature resistance, the achievements of its good sealing function. It can be used to meet the needs of various applications. It is widely used in petrochemical, mechanical, power, metallurgy, shipbuilding, medicine, atomic and aerospace industries by changing the tightening force of the surrounding strip. The

      Polytetrafluoroethylene gaskets are resistant to erosion and are inert to most chemicals and solvents, are resistant to strong acid and alkali, water and various organic solvents. This gasket compression rebound function is good, with multi-channel seal and a certain self-tightening function, the department can eliminate the pressure, temperature changes and mechanical vibration.

      The above is about how the polytetrafluoroethylene gasket is to meet the needs of the market, which is due to poly PTFE gasket has a unique technical design features, and continuously meet the needs of users, also won the majority of users love.
