Sanitary Stainless Steel Tubing

Sieco Vacuum and Hygienic Products Pvt Ltd offers ASTM A270 Sanitary Stainless Steel Tubing for pharmaceutical, bio-pharmaceuticals, dairy, food, beverage, and other sanitary processes. Sieco Hygienic sanitary tubing exceeds ASTM A270 S2 and 3A specifications and most user specifications. The tubing is manufactured from the finest quality stainless steel materials made exclusively to the Sieco melt criteria and formed by the Sieco welding automation pulse TIG/micro plasma process to assure weld seam integrity and industry leading ID and OD finishes to the low Ra values demanded by Sieco S customers. Sieco Hygienic leads the industry in manufacturing the highest quality welded sanitary tubing, backed with technical expertise, advanced manufacturing and polishing capabilities and unmatched service before and after the sale. All standard sanitary tubing sizes are available in 1/2" (12.7 mm) to 6" (152.4) OD in 20' (6.1 m) lengths. Materials: 304L & 316L available from stock. Mechanical tests to ensure the highest surface quality in all of sanitary tubing, Sieco Hygienic goes beyond the requirements of ASTM A269 and A270 by performing the full battery of ASTM bend and deformation tests required by ASME SA 249 as well as additional deformation tests developed by Sieco Hygienic. The tests, combined with specific raw material requirements, eddy current testing at the tube mill, and tighter OD and wall tolerances allow SiecoHygienic to provide a more consistent superior quality product. Annealing: Hydrogen bright annealed in line to 1900°F (1040°C) minimum and rapidly quenched. Surface finishes: 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 profile meter reading at 90 degrees to major polishing pattern. Sieco Hygienic mechanical and electro 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.
