ASTM A213 TP316L Stainless Steel Seamless Tubes Heat Exchanger Application
ASTM A213 is a standard number developed by the American Society for Testing and Materials, which is specifically applicable to seamless ferritic and austenitic alloy steel pipes for boilers, superheaters, and heat exchangers. This means that steel pipes under this standard are designed to withstand high pressure and high temperature environments. TP316L is a low-carbon austenitic stainless steel grade with excellent corrosion resistance and outstanding resistance to chloride pitting corrosion.

Comparison of ASTM A213 TP316L with Other Common Materials
1.vs. 304/304L: The 304/304L series contains no molybdenum and is significantly less resistant to chloride corrosion than 316/316L. Therefore, 304 is a more economical choice for less corrosive environments.
2.vs. 316: The key difference between 316L and 316 lies in its carbon content. If equipment requires extensive welding or undergoes heat treatment during manufacturing, 316L is essential to avoid intergranular corrosion, while standard 316 can be used for simpler components that don't require welding.
3.vs. 317L: 317L has a higher molybdenum content (3-4%) than 316L, resulting in greater resistance to pitting and crevice corrosion than 316L, making it suitable for more demanding environments. However, it also comes at a higher cost.
ASTM A213 TP316L Stainless Steel Seamless Tube Application:
Power Generation Industry: Boilers, superheaters, reheaters, and heat exchanger piping.
Petrochemical Industry: Process piping, heat exchanger tubes, catalyst tubes, etc. in refineries and chemical plants, used to handle various corrosive media.
Food and Pharmaceutical Industry: After internal and external surface polishing, ASTM A213 TP316L stainless steel seamless tube can be used in process piping systems with extremely high requirements for hygiene and corrosion resistance.
Marine and Shipbuilding Industry: Used in seawater cooling systems, ship piping, and other equipment resistant to seawater corrosion.
High-Temperature Gas Treatment: Flue Gas Desulfurization units, exhaust gas treatment systems, etc.
