Absolute roughness, abbreviated as (Greek symbol epsilon), is a measure of the roughness of the inside of a flowing pipe. Absolute Pipe Roughness is usually defined for a material and can be measured experimentally. wall stainless steel tubing purchased to ASTM A269: OD Tolerance 0.005 in. Measured surface for more than 40 years, we have been a trusted for. For example, the absolute roughness of smooth looking aluminum pipes is around 0.001 mm. The value of Ra is normally measured in micrometres. It covers diameters from 1/8" to 30" and thickness from SCH 10S to SCH 80S. Stainless steel electropolished: 0,0001-0,0008: Stainless steel turned: 0,0004-0,006: Stainless steel, bead blasted: 0,001-0,006: Steel pipe after longer use: 0,2: . The Stainless Steel 316L Pipe is used in aqueous applications where chloride ion corrosion is high. Because of this the seamless pipe could be used with precision in high sensitive calculations and applications. The absolute roughness represents the average height of the protruding part of the inner wall of the pipe. Relative roughness can be expressed as, r = k / dh (1), k = roughness of duct, pipe or tube surface (m, ft). Also the notation is important: Ra 0.5 m, for instance, does not have the same meaning as Ra max 0.5 m. The wall roughness of stainless steel pipe usually refers to absolute roughness () and relative roughness ( / D).

From the Engineering Toolbox website ( http://www.engineeri.ubes-d_459.html ), stainless steel has an absolute roughness of 0.015 x 10^-03 m. This is almost exactly a third of the roughness of that of commercial steel that I have seen from other sources. 2B is the most widely used stainless steel surface finish. It is a measure of the complete texture of a product's surface that is defined by three characteristics of surface roughness, waviness, and lay. ,where both the average height surface irregularities and the pipe diameter are in millimeters. U.S. Department of Energy Office of Scientific and Technical Information. There are welded, seamless and fabricated pipes.

My question pertains as to what the absolute roughness of the material might be. The smaller the surface roughness, the smoother the surface. This is a highly reflective, smooth finish, typically produced by polishing with successively finer grit abrasives, then buffing. Absolute roughness is important when calculating pressure drop particularly in the turbulent flow regime. Frantsen, J. E., Mathiesen, T., Specifying Stainless Steel Surfaces for the Brewery, Dairy and Pharmaceutical Sectors, Nace Corrosion, 2009, Paper 09573, [7] Absolute Roughness (k) is a measure of pipe wall irregularities. An alternative measure of surface roughness is the Rz value. 2 If the absolute roughness for commercial steel pipe is 000015 ft what would be. If you are calculating the pressure drop through a full bore ball valve then there is some justification in wanting to know the surface roughness because the overall pressure drop will be so low that the friction against the wall does become a significant fraction of the overall pressure drop.
