Introduction:Sanitary stainless steel tube is cold-rolled polishing stainless steel pipe with high dimensional accuracy as below.
Outside diameter of 38mm or less: outside diameter limit deviation ± 0.03mm, inside diameter limit deviation± 0.04mm
Outside diameter of 38mm or above: outside diameter limit deviation ± 0.05mm, diameter limit deviation± 0.06mm
Roundness is generally controlled within 1mm range
Wall thickness at 2mm, tolerance is within ± 0.05mm,
Wall thickness of 3-6mm, tolerance is within ± 0.08mm
General surface roughness range:
Pickling(Ra ≤ 2.5 μm) mechanical polishing (Ra ≤ 0.4 μm), bright polishing (Ra ≤ 0.3 μm), electrolytic polishing (Ra ≤ 0.2 μm)
