        PTFE Envelope Gasket

        Item No.:ZD-G1700

        Description: ZD-G1700 PTFE envelope gasket are use for type of static seal. ZD-G1700 is composed of elastic materials and it has superior properties against chemical (not affected by all chemicals except molten alkali metal and fluorine at elevated temperature).It also has a wide working temperature range,low coefficient of static and dynamic friction. ZD-G1700 is the best of the “non-stick” materials. PTFE envelope gasket has excellent weathering and aging characteristics.

        Application:ZD-G1700 PTFE envelope gasket is used to seal pipe flanges glass lined, PVC or FRP.ZD-G1700 has low bolt torque effecting a seal and chemical compatibility.

        The Material of Insert:

        Gasket material
        temperature ℃
        pressure MPa
        Asbestos clad plate
        150

        Drawing of Cross Section:

                                   

         U Style                                                                     V Style

        Types:
        A. dissection cut type
        It has a cladding mouth, so it is an economical gasket used in low pressure, and has very good effects on leveling, compressed metal, porcelain and glass sealing surface. It is also called cladding gasket of Y-type dissection.
        Cut it into 0.8MM---1MM ring-shaped sheet with cylinder material truck, divide it from the center of outer side thickness, put core materials into the cut mouth, which is about 1.5---2.0MM away from the inner hole.
        B. folding type
        It is cladding gasket of left frame-type dissection, with its inner diameter the same with that of flange, so as to prevent the liquid from whirlpooling in the flange, so the inside air has very small expansion amount and good sealing performance. This kind of gasket is often made of reinforcing materials of graphite, open asbestos and rubber.
        C. mechanical processing type
        Often used in high-pressure medium, this kind of gasket is cladded with machines. The filling materials are generally constringent materials and rubber. The two ends of 0.4—0.8MM thick strap-shaped PTFE film are heated and covered outside the ring-shaped core materials, to show U shape.

        Main Specification:

        Pressure

         =<4.0MPa

        Temperature

         -180℃-260℃

        PH

         0-14

        Gasket factor

         m=2.5

        Gasket Seating

         y=20MPa

        Size

        OD=<1100mm(special size can be made as request)

         

        Warning: Gasket materials should never be recommended when both the temperature and the pressure are at the maximums listed.  Properties and applications shown are typical.  No application should be undertaken by anyone without independent study and evaluation for suitability. Never use more than one gasket in one flange joint, and never reuse a gasket.  Improper use or gasket selection could cause property damage and/or serious personal injury.  The data reported is a compilation of field testing, field service reports and/or in-house testing.  While the utmost care has gone into publishing the information contained herein, we assume no responsibility for errors.  The information and specifications  contained in this website are subject to change without notice.
