ASME SA213 TP316L Seamless Stainless Steel U Bend Oil Boiler Tubes
Leave a message
ASME SA213 TP316L seamless stainless steel U-tubes for oil boilers are high-performance tubes conforming to the ASME SA213 standard, manufactured from Type 316L austenitic stainless steel using a seamless process and formed into U-tubes for corrosion-resistant applications in high-temperature environments such as boilers, heat exchangers, and oil systems.
The TP316L grade tubes exhibit excellent resistance to pitting and crevice corrosion in chloride environments due to their high molybdenum content and low carbon content, which also enhances their weldability. These tubes can operate at high temperatures of up to approximately 1000°C. The ASME SA213 U-bend shape allows the heat exchanger tube sheet to expand and contract without stress, making them suitable for high-temperature and high-pressure applications.
