PTFE Teflon Bellows

We are offering ptfe teflon bellowsdescription: bellows are specially designed from virgin ptfe and is contour moulded. This manufacturing method guarantees an excellent structure of the material; symptoms of ageing are practically excluded. Very long term durability and low maintenance cost are assured. The bellows can be used upto 260°c. Bellows serve for compensation of vibration, thermal strain expansion and axial & redial motion. These bellows are meant for resisting highly corrosive plants and piping for aggressive medias. These bellows are installed in ptfe lined carbon steel piping and equipment without additional gaskets. For use with piping and equipment made of glass, enamels and ceramics we recommend ptfe gaskets, offered as accessory. The sealing surfaces are covered end plates and individually boxed for protection against mechanical damage. Limit bolts are preset to prevent over extension during operation.   size: bellows are manufacturing in different sizes from nb 25mm to nb 300mm. The standard length is 67.5mm long.   general ptfe properties chemical resistance ptfe is resistant to virtually all chemicals, even at very high temperature and pressures. It is only affected under certain conditions by elementary fluorine, strong fluorinating agents (such as chlorine trifluoride) and molten alkali metals (such as metals sodium). temperature resistance: ptfe components can be used at temperatures ranging from approximately -200oc to +260oc electric insulator: ptfe has excellent electric properties which remain constant independent of frequency and temperature. coefficient of friction: ptfe has the lowest coefficient of friction of all solid materials anti-stick effect: ptfe is an anti-adhesive, i.e. Other materials do not adhere to ptfe no health hazard:   ptfe can be safely used upto temperatures of +260oc (does not apply to all fillers).
