Introduction Corrosion Resistant Products (CATALOG)

Corrosion Resistant Products CRP has been designing, processing and manufacturing top quality paste extruded PTFE and PFA lined products for more than 30 years. All of our products originate from our manufacturing site near Manchester, UK. Using qualified materials, robust and repeatable manufacturing process technologies and a depth of experience CRP are able to deliver product for the most exacting applications.

• Product Overview

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, undertaking innovative long term pressure increase testing.

The Product Family The bellows product range covers 19 sizes from 1in to 32in. They are manufactured in two materials—virgin PTFE and static dissipating PTFE. FluoroFlow Bellows in sizes 1in to 8in 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. For products requiring a higher pressure rating than is possible with PTFE alone, we have our range of armoured bellows (FFAB) where the PTFE is surrounded by a high pressure stainless steel shell.

HiPerFlon® HiPerFlon® is a second generation paste extruded High Performance PTFE. HiPerFlon® has the greatest mechanical properties and lowest permeation rates of PTFE materials and as such provides high pressure ratings, long lifetime, low maintenance costs and consequently the lowest cost of ownership.
