ASTM A213 TP316L Serrated Finned Tube , For Petrochemical And Chemical Processing
A serrated finned tube is a type of enhanced heat transfer tube equipped with fins that have serrations (cut or notched edges). These fins are helically wound and tightly bonded to the tube surface, increasing the surface area for heat exchange and improving heat transfer efficiency.
Serrated Finned Tubes made from ASTM A213 TP316L are widely used in heat transfer applications due to their excellent thermal efficiency, corrosion resistance, and suitability for harsh environments.
Material Description:
ASTM A213 TP316L is a low-carbon variant of 316 stainless steel. The "L" in 316L stands for "low carbon," which enhances its resistance to intergranular corrosion, especially after welding. This austenitic stainless steel is highly durable in both high-temperature and corrosive environments, making it ideal for heat exchanger applications.
Key Features:
Corrosion Resistance:
· Excellent resistance to oxidation, chloride-induced corrosion, and acidic environments, particularly in marine and chemical processing applications.
Thermal Efficiency:
· Serrated fins increase the heat transfer surface area and promote turbulence in the fluid, significantly enhancing thermal efficiency compared to plain tubes.
Durability and Strength:
· TP316L material provides high tensile strength and durability, ensuring stable performance in high-pressure and high-temperature environments.
Weldability and Longevity:
· Low carbon content improves weldability and minimizes the risk of intergranular corrosion after welding, ensuring long service life.
