TP316 stainless steel condenser tube undergoes solution annealing treatment (1010-1120℃ insulation) to inhibit the precipitation of chromium carbide after welding. It needs post-weld annealing to meet the ASTM A262 intergranular corrosion test. It is suitable for small and medium-sized condensing equipment that can be heat treated. After stress relief annealing, the vibration fatigue life reaches 300,000 cycles, and the risk of fracture is reduced by 40% compared with 304 stainless steel condenser tube.
TP316 Stainless Steel Steam Condenser Tube has a pitting resistance equivalent (PREN) of 24-28, and its chloride ion corrosion resistance is 2 times higher than that of 304 stainless steel. The tensile strength is ≥515MPa, the yield strength is ≥205MPa, and it can withstand a design pressure of 8MPa. It is suitable for medium and high pressure steam condensing systems.
In addition, GNEE offers various surface finishes for stainless steel tubes, including mirror polishing (8K), hairline finish, brushed polishing (No.4), and pickling and passivation. We supply stainless steel tubes in a wide range of sizes, grades, and shapes, all manufactured to meet international quality standards and fully tested. You are welcome to purchase TP316 stainless steel tubes from us at competitive prices.

Q: How is TP316 different from TP304 in condenser applications?
A: TP316 offers better corrosion resistance in chloride-rich environments compared to TP304, making it more suitable for seawater or chemical processing condensers.
Q: What are the standard dimensions for TP316 condenser tubes?
A: Outer diameters typically range from 6.35 mm to 50.8 mm, with wall thicknesses from 0.5 mm to 2.0 mm, depending on the design and standards like ASTM A213 or A249.
Q: Can TP316 stainless tubes be used with ammonia or seawater?
A: Yes, TP316 is compatible with both mildly acidic solutions like liquid ammonia and chloride-rich environments such as seawater, thanks to its molybdenum content.
Q: Is TP316 suitable for high-temperature condenser applications?
A: TP316 can be used in temperatures up to about 870°C intermittently, tho
