Custom Stainless Steel Sanitary Pipe ASTM A270 TP304 304L TP316 316L TP321 321H TP347
Allied Rainbow Group’s sanitary tubing exceeds ASTM A270 S2 and 3A specifications and most user specifications. It is manufactured from the finest quality stainless steel materials made exclusively to the Allied Rainbow melt criteria and formed by the Allied Rainbow Micro-Weld™ process to assure weld seam integrity and industry leading ID and OD finishes to the low Ra values demanded by Allied Rainbow Group’s customers. Allied Rainbow Group 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 (6 mm) to (203.2 mm) OD in stock 20' (6.1 m) lengths.
To ensure the highest surface quality in all of our sanitary tubing, Allied Rainbow Group 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 Allied Rainbow Group The tests, combined with specific raw material requirements, Eddy Current testing at the tube mill, and tighter OD and wall tolerances allow Allied Rainbow Group 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. RathGibson’s polishing techniques result in surface finishes that lead the industry. All tubing is printed with size, ASTM and ASME specifications, heat number and date of manufacturing for full trace ability.As a final
step in maintaining purity standards, Allied Rainbow Group’s A270 tubing is packaged using protective 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.
