1. Introduction
ASTM A213 TP304 U-tube is an austenitic stainless steel seamless tube designed for high-temperature and high-pressure equipment. It is widely used in key components such as boilers, heat exchangers, and condensers. TP304 stainless steel has excellent corrosion resistance and high-temperature strength. Its U-shaped bending structure can effectively absorb thermal expansion stress and is suitable for complex piping systems. The material complies with the ASME SA-213 standard, ensuring reliability and long life under extreme working conditions.
