non stick
Very few solid substances will permanently adhere to "GARG PTFE" linings. And while tacky materials may show some adhesion, almost all substances release easily.

non-wetting
Since "GARG PTFE" surfaces are both oleo phobic and hydrophobic, they are not readily wet. Clean-up is easier, more thorough and in many cases self-cleaning.


heat-resistance
There is no decomposition of  "GARG PTFE" finishes below 400 degree F; insignificant decomposition between 400 degree F and 500 degree F, which requires no special precautions. Between 500 and 575 degree F, intermittent service is possible with adequate ventilation.

low coefficient of friction
The coefficient of friction of "GARG PTFE" is generally in the range of 0.05 to 0.20, depending on the load, sliding speed and particular "GARG PTFE" finish used.

cryogenic stability
Many "GARG PTFE" will withstand severe temperatures extremes without loss of physical properties. "GARG PTFE" may be considered for use at temperatures as low as -450 degree F.

unique electrical properties
Over a wide range of frequencies, "GARG PTFE" has high dielectric strength, a low dissipation factor, and a very high surface resistivity. By special techniques, it can even be made conductive enough to be used as an anti-static coating.

chemical resistance
"GARG PTFE" is normally unaffected by chemical environments However, certain coatins are permeable or have a lower reistance to attack. The only chemicals known to affect all "GARG PTFE" finishes are the alkali metals and highly reactive flourinating agents.

Bellows are made of pure virgin PTFE (Polytetraflouroethylene). Paste extruted and contour molded material.

This manufacturing method guarantees an excellent structure of the material; symptoms of ageing are practically excluded.

Very long-term durability and low maintenance costs are assured.

Bellows server the compensation of:-

-vibrations

-thermal strain and expansion

-axial, angular and radial motion,

and because of the outstanding chemical resistance of PTFE, are mostly used in chemical plants and pipes for aggressive media.

Bellows are manufactured in different types sized from NB 25mm to NB300mm. The allowable Bellows are manufactured in different types sized

from NB 25mm to NB300mm. The allowable operating pressure are depending on design. The bellows can be used upto 210 degree C. At extreme temperatures, the maximum pressure allowable is restricted.

Bellows are available with three convolutions for pressure.

Bellows are installed in PTFE Lined Carbon Steel piping and equipment without additional gaskets. For use with piping and equipment made of glass, enamel and ceramics We recommend PTFE gaskets, offered as accessory. The sealing surfaces are covered with end plates and individually boxed for protection against mechanical damages. Limit bolts are present to prevent over extension during operation.
