Stainless Steel ASTM A213 TP304, TP304L Seamless U Bend Tubes For Heat Exchanger
ASTM A213 TP304 / TP304L is the most common grade of Stainless Steel. It has the austenitic microstructure with the addition of nickel, nitrogen, manganese, which offers excellent weldability and good formability. When it comes to U bend tubes, they are commonly used in heat exchangers where the tubes need to make a U-turn for the purpose of changing the direction of the fluid flow. U bend tubes are typically made from stainless steel due to its corrosion resistance and heat transfer properties. YUHONG GROUP is manufacturer and supplier of stainless steel U bend tubes for more than 30 years.
Key Features and Specifications:
Material: The base material is TP304 stainless steel, which is a widely used austenitic stainless steel grade with good corrosion resistance, heat resistance, and formability.
Tube Dimensions: The tubes typically have specified dimensions, including outer diameter, wall thickness, and length. U bend tubes are specifically designed to have a U-shaped bend.
Heat Treatment: Tubes made according to ASTM A213 TP304 may undergo heat treatment as specified in the standard to achieve the desired mechanical properties.
Testing and Inspection: The tubes must undergo various tests and inspections to ensure they meet the specified requirements. Common tests include hydrostatic testing, eddy current testing, and mechanical property testing.
Surface Finish: The tubes may have a specified surface finish to meet certain aesthetic and corrosion resistance requirements.
Applications: U bend tubes made from ASTM A213 TP304 stainless steel are commonly used in applications such as heat exchangers, boilers, and superheaters in various industries including petrochemical, chemical, and power generation.
