CRP FLUOROFLOW PTFE BELLOWS

CRP FluoroFlow PTFE Expansion Bellows

The FluoroFlow Bellows (FFB) range has been engineered over 40 years to compensate for thermal expansion in pipelines, for the protection of fragile process equipment such as graphite, plastic or glass and the isolation of vibration hazards.  PTFE bellows come into their own for corrosive, high purity or hot applications. CRP has some unique manufacturing processes based upon the use of paste extruded PTFE, and a proprietary convolution process. These have been independently tested by the internationally recognised safety and quality group TÜV for both traditional short term bench mark performance testing and innovative long term pressure increase testing.

The Product Family

The bellows product range covers 19 sizes from DN25/1” to DN800/32”.  They are manufactured in two materials—virgin PTFE and static dissipating PTFE.  FluoroFlow Bellows in sizes DN25/1” to DN150/6” are available in extra heavy duty only.   For larger diameters there is a choice of two wall thicknesses—a heavy duty (HD) and extra heavy duty (XHD).  The bellows can be manufactured with 2 to 10 convolutions.  However, this is just the standard  product. The flexibility of the manufacturing method is such that many special configurations can be produced to meet specific customer requirements. ASME class 150, DIN PN 10 / 16 and other flanges types can be readily supplied.

For higher pressure rating products than PTFE alone can withstand we have our range of armoured bellows (FFAB) where the PTFE is surrounded by a high pressure retaining stainless steel shell.
