Hygienic Austenitic SS Sanitary food grade stainless steel pipe Smooth Surface Easy Clean For Food
Cleanliness, sterilization and safety are mission-critical factors in order to maintain and deliver quality products to their consumers especially for the food, beverage and pharmaceutical industries. The tube inside wall must be extremely smooth, cervice-free, in order to avoid all possible corrosions and ensure the better flow of fluid, easy to clean up and long hygienic conditions.
Inline hydrogen bright annealing to 1900 F (1040 C) minimum followed with a rapid quench.
Surface finish is 20 u-in Ra (0.5um) ID maximum, 30 u-in Ra (0.8um) OD maximum surface roughness measured per ASME/ANSI B46.1 with the profilo-meter reading at 90 degree to the lay. Other finishes available upon request.
As a final step to ensure purity standards, each tube is packaged using 2 mil poly sleeving and both ends are sealed using air tight end caps. Stainless steel sanitary pipes are packaged in protective tri-wall boxing. When specified, woode boxes and all export requirements can be provided.
This stainless grade is similar to that of the 304 grade, but with additions of molybdenum, greater corrosion resistance and improved high temperature strength is achieved. Corrosion resistance to lower pH and chloride solutions can be attributed to this particular grade's combination of stainless alloying elements. 316L grade is an extra low carbon version of 316 which offers additional resistance to carbide precipitation during welding, therefore eliminating the need for post weld annealing in most cases. Applications include parts exposed to marine atmospheres, furnace components, heat exchanger tubes, and exhaust manifolds.
