Abstract
ASTM A270 covers grades of seamless, welded, and heavily cold worked austenitic and ferritic/austenitic stainless steel sanitary tubing. Seamless tubes shall be manufactured by a process that does not involve welding at any stage. Welded tubes shall be made using an automated welding process with no addition of filler metal during the welding process. 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. Longitudinally polished finish shall be performed on the inside surface only while a circumferential polished finish shall be done on either the inside surface, outside surface, or both.
Sanitary Stainless Steel Tube is mainly made of 2 different austenitic stainless steel grades. Most sanitary tube is made of SS304 or SS316L. These are both of good strength and high temperature capable. SS316 have excellent ductility and so they could be formed into unusual shapes. Manufacturers use a low carbon version of the alloy to improve its weldability. However, in the case of A270 TP316L, the specification ASTM A270 does not include prerequisites for welding. Though if a welding operation is to take place, the welded SA270 TP316L Sanitary Stainless Steel Tube must be minus any filler metals. And the welding procedure carried out is to be an automatic one. The problem associated with welding is the formation of carbide precipitates which causes the component to corrode.
Therefore, the use of A270 TP316L Sanitary Tube solves the problem by eliminating intergranular corrosion. In industries like the food and beverage, that makes use of ASTM A270 Sanitary Tubing, the interior walls of the tube come in contact with certain actives present in food. Similarly, in the case of the pharma sector, there are various acid derivatives or highly volatile compounds that come in contact with the walls of the A270 TP316L Sanitary Stainless Tube.
