AF Flex Centraliser
There are three different types of AF Flex Centraliser available all with slightly different applications. The original centraliser was developed to fit larger pipe sizes, where it became impractical to use AF Flex support design on pipe sizes generally above 8″ (DN200) inner pipe size. This is referred to as the Type A centraliser in the brochure. The Type A centraliser offers a high stiffness, and large degree of flexibility in the radial direction, but is a more complicated construction, and therefore more expensive product. On pipe sizes greater than 8″ or DN200 it is recommended to use the Type A centraliser where a large amount of radial displacement is required (for example around bends) , and then use the more economical Type B centraliser for axial displacement only.
