With abundant experience, we warmly welcome you to wholesale customized asme sa213 tp304l seamless u bend tube for boiler from our factory. For price consultation, contact us.
ASTM A213/ASME SA213 TP304 is the standard specification for seamless ferritic and austenitic alloy steel boiler, superheater, and heat exchanger tubes. A U-bend tube is a specialized tube designed for heat exchangers, formed into a U-shape to facilitate efficient heat transfer.
ASME SA213 TP304 U-bend tube is made from TP304 stainless steel, an austenitic stainless steel grade. These tubes are manufactured by cold bending straight tubes into the required U-shape using specialized bending machines. They are commonly used in applications that require transferring heat from one fluid to another, such as in boilers, heat exchangers, and condensers.
Available in a wide range of sizes and wall thicknesses, TP304 U-bent tubes can be customized to meet the specific requirements of different industrial applications.
Applications:
ASTM A213 TP304L stainless steel pipes are widely used in heat exchangers, condensers, evaporators, and oil systems in industries such as power generation, petrochemical, and HVAC, where corrosion resistance, thermal stability, and leak-free performance are critical.

Product Testing
GNEE Stainless Steel is a specialized manufacturer of Stainless Steel U Bend Tube / Stainless Steel U bent Tubes for U Tube Heat Exchanger (U bent Stainless Steel Tube for U bent Tube Heat Exchanger). Our U Bend Tube Tube-bending production line, installed in 2008. Solution annealing after bending will be processed to lower the residual stress, and followed by Hydrostatic testing/Pneumatic test and Dye Penetrant testing if required.
Packaging
All tubing shall be packaged and blocked in such a manner as to prevent damage in ordinary handling and transportation. The boxes shall be constructed in such a manner that no nails, staples, screws, or similar fasteners are required to close and secure the box after the tubes have been placed in the box. The box shall be lined with plastic sheet or vapor barrier materials so as to prevent chloride contamination of the tube during handling, transportation, and storage.
