Stainless steel sanitary tubing for use in dairy and food industries, pharmaceutical industry and other applications requiring special surface finishes.
To assure the highest quality standards, our stainless steel sanitary pipe is subjected to extensive testing and inspection programs that meet or exceed ASTM A270/A1016/A1016M test requirements. Testing includes reverse bend, reverse flattening, and flange tests. Eddy current testing is performed on 100% of the stainless steel sanitary pipe produced.
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.

304 is the standard '18/8' stainless and known to be the most versatile and most widely used stainless steel. It is chosen for its suitability for use in highly corrosive environments, resistance to chromium carbide precipitation, high formability and high weldability. 304L grade is an extra low carbon version of 304 which offers additional resistance to carbide precipitation during welding, therefore eliminating the need for post weld annealing in most cases. Applications include kitchen equipment, welded components of chemical, textile, pharmaceutical and paper processing equipment, cosmetic automotive trim, air bag inflator tubes, automotive and truck exhaust components.
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.
