To ensure the highest surface quality in all of our sanitary tubing,Yuhong Group goes beyond
the requirements of ASTM A269 and A270 by performing the full battery of ASTM bend and deformation
tests required by ASME SA249 as well as additional deformation tests developed by Yuhong Group The tests, combined with specific raw material requirements, Eddy Current testing at the tube mill,
and tighter OD and wall tolerances allow Yuhong Group to provide a more consistent superior
quality product.Hydrogen bright annealed in line to 1900°F (1040°C) minimum and rapidly
quenched.Surface finish is 20 μ-in Ra (0.5 μm) ID maximum, 30 μ-in Ra (0.8 μm) OD maximum surface
roughness measured per ASME/ ANSI B46.1 with the profilometer reading at 90 degrees to major polishing
pattern.
