To ensure the highest surface quality in all of our sanitary tubing,Yuhong Special Steel 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 Special Steel The tests, combined with specific raw material requirements, Eddy Current testing at the tube mill, and tighter OD and wall tolerances allow Yuhong Special Steel 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.Yuhong Special Steel’s polishing techniques result in surface finishes that lead the industry.
All tubing is printed with size, gauge, alloy, ASTM and ASME specifications, heat number and date of manufacturing for full traceability.As a final step in maintaining purity standards, Yuhong Special Steel’s A270 S2 tubing is packaged using protective 2 mil poly sleeving along with air tight plastic end caps. The tubing is then placed in triple wall boxes for maximum protection during shipment. Other packaging is available on request.
