Surface roughness is largely responsible for the wear experienced by seals. In order to provide some protection for elastomers, which are liable to become scratched, very strict regulations are laid down with regard to surface roughness: For the purpose of sealing non-moving surfaces, an R a of 0.5 to 1.5 μm is often used. However, in order to

Relative Roughness - an overview | ScienceDirect Topics

The absolute roughness of 0.0018″ is for aged pipe, but accepted in design practice because it is conservative. Flexible pipe is rougher than steel pipe, therefore, requires a larger diameter for the same maximum rate. For a flexible pipe, the roughness shall be given by ε = ID/250.0 unless alternative specifiion is given. The roughness may increase with use at a rate determined by …
