Bellows are made of pure virgin PTFE(Polytetraflouroethylene). Pasteextruted 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 andpipes for aggressive media. |
Bellows are manufactured in different types sized from NB 25mm to NB300mm. The allowable Bellows are manufactured in different typessized from NB 25mm to NB300mm. The allowable operating pressure aredepending 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. |
