It is manufactured from the finest quality stainless steel materials made exclusively to the Ganyeah melt criteria and formed by the Ganyeah Micro-Weld™ process to assure weld seam integrity and industry leading ID & OD finishes to the low Ra values demanded by Ganyeah's customers. Ganyeah leads the industry in manufacturing the highest quality welded sanitary tubing, backed with technical expertise, special manufacturing and polishing capabilities and unmatched service before and after the sale. All standard sanitary tubing sizes 1/2" (12.7 mm) to 6" (152.4 mm) OD in 20 ft. (6.1 m) lengths are available with polished ID & OD for same day shipping.
Materials • 304L & 316L available from stock. 6-MOLY and other alloys available on request. See reverse side for complete specifications regarding materials and dimensional tolerances.
Mechanical Tests • To ensure the highest surface quality in all of our sanitary tubing, Ganyeah 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 Ganyeah. The tests, combined with specific raw material requirements, eddy current testing at the tube mill, and tighter OD and wall tolerances allow Ganyeah 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 • SUS304 Sanitary Stainless Steel Tubing is supplied with bright annealed finishes or mechanically polished to 20 µ-in Ra (0.5 µm) ID maximum and/or 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. Ganyeah's polishing techniques result in surface finishes that lead the industry. Tubes are printed with size, gauge, alloy, ASTM and ASME specifications, heat number and Ganyeah mill operator initials for full traceability.
Packaging •As a final step in maintaining sanitary process standards, Ganyeah SUS304 Sanitary Stainless Steel Tubing is protected with plastic caps and sealed in 2-mil poly sleeves to prevent contamination. Tubing is packed in sturdy triple-wall cardboard boxes with wood ends and banded for optimum protection during shipping. Other packaging options include cardboard sleeves or wood boxes
