Food Grade Stainless Steel Seamless Tube ASTM A270 TP304 Polished/Mirror Surface

Hua Dong Energy Technology food grade tube 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

Hua Dong Energy Technology melt criteria and formed by the Hua Dong Energy Technology Micro-Weld™ process to

assure weld seam integrity and industry leading ID and OD finishes to the low Ra values demanded by

Hua Dong Energy Technology ’s customers. Hua Dong Energy Technology eads 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 8" (203.2 mm) OD in stock 20' (6.1 m) lengths.

Chemical Composition:

Dimensional Tolerences
all dimensions in inches (mm)

To ensure the highest surface quality in all of our sanitary tubing,Hua Dong Energy Technology 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 Hua Dong Energy Technology

tests, combined with specific raw material requirements, Eddy Current testing at the tube mill,

and tighter OD and wall tolerances allow Hua Dong Energy Technology o 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.Hua Dong Energy Technology’s 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.As a final step in maintaining purity standards, Hua Dong Energy Technology’s

A270 S2 tubing is packaged using protective 2 mil 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.
