Stainless Steel Sanitary Tube ASTM A270 TP316L Chemical Natural gas Petroleum​

Austenitic stainless steel alloys, including grade 316, tend to have excellent ductility, so they can be formed into unusual shapes. However, manufacturers use lower carbon versions of this alloy to improve its weldability. However, in the case of ASTM A270 tp316l, specification ASTM A270 does not include prerequisites for welding. However, if a welding operation is to be performed, the welded ASME SA270 TP316L sanitary stainless steel pipe must be minus any filler metal. And the welding procedure performed must be automatic. A problem associated with welding is the formation of carbide precipitates, which will lead to corrosion of the component.

Therefore, the use of low carbon astm a270 tp316l sanitary tubing can solve this problem by eliminating intergranular corrosion. In industries such as food and beverage where ASTM A270 sanitary tubing is used, the inner wall of the tubing comes into contact with certain active substances in the food. Similarly, in the pharmaceutical industry, there are various acid derivatives or highly volatile compounds that come into contact with the walls of ASTM A270 TP316L sanitary stainless steel tubing.

This can cause problems in the area of the weld, as some of the reactions between the products may be exothermic and give off heat. In addition, these processes may also leave some residue of the product that can stick to the inside of the ASME SA270 TP316L tube wall. Thus, specifications like ASTM A270 offer manufacturers a variety of surface treatment alternatives that can be used to treat the internal and external surfaces of SA 270 TP316L stainless steel tubing.
