What Is Sf1 Surface Finish. the bpe specs for interior surface roughness are identified as sf1 (20ra mechanical) and sf4 (15ra with electropolish). since their initial release in 1997, the asme bpe standards have become the standard in the biopharmaceutical industry. the standard designates 6 different acceptable surface finishes, the most common sf1 (maximum 20 ra) and. to this end, asme has designated seven levels of surface finish, with each having specific requirements regarding how the surface is prepared. this electropolishing specification includes seven surface finishes that may be used when specifying surface finishes. exclusively tubes, fittings and valves with a smooth internal surface that is not only easy to clean, but it. It should be noted that the spec does not address the outside surface which should not come in contact with the product. 0,51 µm > pulled or mechanical polished. the difference between these 2 variants is the way of obtaining the internal surface finishing. standard dt fittings and tube are offered to sf1 surface finish at 0.51µm ra max as standard with sf4 (0.38µm ra max) being available on special.
