SA213 TP304L Austenitic Stainless Steel Tube, Cold-Drawn And Bright Annealed, Ideal For Heat Exchangers/Condensers
Overview of Bright Annealed A213 TP304L Stainless Steel Seamless Tube
Bright Annealed A213 TP304L seamless tubes are high-quality, austenitic stainless steel tubes manufactured to ASTM A213 specifications. Made from TP304L, a low-carbon variant of 304 stainless steel, these tubes are cold-drawn and bright annealed in a controlled atmosphere to achieve a smooth, reflective, oxide-free surface finish.
The bright annealing process enhances corrosion resistance, cleanliness, and dimensional precision, making these tubes ideal for heat exchangers, condensers, instrumentation lines, and high-purity applications in industries like pharmaceuticals, food processing, and petrochemicals.
Advantages of A213 TP304L BA Tube:
-
Superior corrosion resistance
-
High dimensional accuracy
-
Hygienic and easy to clean
-
Suitable for high-temperature service
