smooth surface d steel pipe 4
DOM round steel tubing is a type of high quality welded tubing that has been cold worked and drawn over a mandrel to create a smooth surface finish and dimensional accuracy. The interior weld seam is also removed to create a smooth interior surface, creating steel tube with uniform concentricity and wall thickness and enhanced mechanical FRICTION FACTORS FOR SINGLE PHASE FLOW IN SMOOTH Friction factor of commercial pipes can be calculated using equation (5) if the pipe roughness is in the completely rough region. In the transition region where the friction factor depends on both Reynolds number and the relative roughness (/D), the friction factor of the commercial pipe is found to be different from those obtained from the sand roughness used by Nikuradse (see Figure 2).

Not all flow conduits are circular pipes. An example of a non-circular cross-section in heat exchanger applications is an annulus, which is the region between two circular pipes. Pipe Roughness Data - eFunda600 to 3000. 0.2 to 0.9 mm. concrete. 1000 to 10,000. 0.3 to 3 mm. riveted steel. 3000 to 30,000. 0.9 to 9 mm. Relative pipe roughness is computed by dividing the absolute roughness e by the pipe diameter D ,
Determine the friction factor (f D) for fluid flow in a pipe of 700mm in diameter that has the Reynolds number of 50 000 000 and an absolute roughness of 0.035 mm. . Solution:The relative roughness is equal to = 0.035 / 700 = 5 x 10-5.Using the Moody Chart, a Reynolds number of 50 000 000 intersects the curve corresponding to a relative roughness of 5 x 10-5 at a friction factor of 0.011. Roughness & Surface Coefficients - Engineering ToolBoxSurface coefficients to calculate flow friction and major pressure loss - surfaces like concrete, galvanized steel, corroded steel and more. For turbulent flow the friction coefficient depends on the Reynolds Number and the roughness of the duct or pipe wall.

A smooth surface is less susceptible to an accumulation of deposits and stainless, which often become focal points for localised corrosion. All stainless steel finishes perform better when cleaned and maintained and details of correct cleaning procedures may be found in our publication, The Cleaning and Maintenance of Stainless Steel.
