ASTM A270 / A270M TP316L Stainless Steel Sanitary
ASTM A270 sanitary stainless steel tubing is the standard specification for the welded seamless， and heavily cold worked welded austenitic and ferritic stainless steel sanitary tubing. It includes the stainless steel tube types in seamless and welded ERW， EFW. ASTM A270 sanitary tubing intended applied in the diary and food industry， bio processing equipment， and having special surface finish. Heavily cold worked tubes shall be made by applying cold working of not less than 35% reduction of thickness of both wall and weld to a welded tube prior to the final anneal. No filler shall be used in making the weld.
All material shall be furnished in the heat-treated condition. A chemical analysis of either one length of flat-rolled stock or one tube shall be made for each heat. Each tube shall be subjected to mechanical tests like reverse flattening test， hydrostatic test or nondestructive electric test.
ASTM A270 Sanitary Stainless Steel Tube Size Range
ASTM A270 sanitary stainless pipe usually refers to the small pipe diameters， normally from 1/2” to 2 1/2”， thickness from 0.049 in (1.24mm) to 0.15 in (3.81mm). Length can be fixed or random
The maximum outer diameter of ASTM A270 tubing is 12 inches (304.8 mm).
ASTM A270 tubing using inch-pound as the standard unit of measure.
Wall thickness tolerance shall not vary more than 12.5%.
