What is ASTM A213 Stainless Steel Heat Exchanger Tubes?
ASTM A213 is the standard specification for seamless ferritic and austenitic alloy-steel boilers, superheaters, and heat-exchanger tubes, making it the premier standard for power plants, refineries, and petrochemical furnaces. This standard covers a wide variety of steel grades, including TP304, TP316, TP321, TP347, TP304H, and TP347H. Usually supplied in a solution annealed condition, these seamless stainless steel tubes feature a minimum wall thickness. The standard surface finishes are typically Annealed & Pickled (AP) or Bright Annealed (BA).

Our ASTM A213 stainless steel heat exchanger tubes are manufactured using hot-finished or cold-drawn processes. Compared to welded options, ASTM A213 seamless tubes deliver superior pressure rating capacities, uniform wall thicknesses, excellent thermal fatigue resistance, and a significantly minimized risk of leakage under high-temperature and high-pressure working conditions.
To meet diverse project specifications, GNEE offers seamless heat exchanger tubes ranging from 6.35 mm to 127 mm in outside diameter (OD) and 0.5 mm to 12.7 mm in wall thickness. Products are available in straight lengths and U-bent tubes, supported by custom fabrication services such as precision cutting, bending, polishing, pickling, and passivation. Prior to export, every single tube undergoes strict inspection for dimensional accuracy, surface quality, and corrosion resistance. They are packed in seaworthy packaging-equipped with plastic end caps and robust wooden boxes-to prevent any damage during transit.

How to Choose ASTM A213 Heat Exchanger Tubes?
When selecting ASTM A213 heat exchanger tubes, it is necessary to match the material grade to the corrosiveness of the fluid, determine appropriate temperature limits, specify minimum wall thickness requirements, and ensure a seamless construction to meet durability needs under high-pressure conditions. Unlike welded tubes (ASTM A249), the ASTM A213 standard is applicable to high-temperature, high-pressure service conditions that demand exceptional tube wall integrity.
To provide a more specific recommendation, please tell me:What fluids or gases are running inside and outside the tubes?What are the operating temperature and pressure ranges?Do you require any special testing or certifications (such as NACE compliance or PMI)?

Quality Control
Eddy Current Testing (ECT): 100% eddy current inspection of every tube to detect minute defects on both inner and outer surfaces.
Hydrostatic Test: Each tube is held at the specified pressure for a minimum of 5–10 seconds.
Dimensional Inspection: Measurement of outside diameter (OD), wall thickness (WT), and roundness using digital micrometers and go/no-go gauges.
Flaring & Flattening Tests: Verification of material ductility to ensure integrity during on-site flaring connections.
Intergranular Corrosion (IGC) Test: ASTM A262 testing performed on materials such as TP316L and TP321.
High-Quality Packaging
End Protection: High-strength plastic caps are fitted to both ends to prevent dust from entering the inner walls and to protect the ends from impact-induced deformation.
Surface Wrapping:
Bright Annealed (BA) tubes: Individually sleeved in plastic bags, then packed in layers.
Pickled (AP) tubes: Fully wrapped in waterproof woven fabric or VCI anti-rust film.
Reinforced Wooden Crates: For heat exchanger tubes, GNEE mandates the use of fumigation-free plywood crates (compliant with ISPM-15 international export standards).
FAQ
What is the difference between ASTM A213 and ASTM A249?
The primary difference between ASTM A213 and ASTM A249 is the manufacturing method: A213 specifies seamless tubing, while A249 specifies welded tubing. Both are utilized for high-temperature and high-pressure equipment like boilers and heat exchangers.
Why is a bright annealed (BA) surface recommended for heat exchanger tubes?
Bright annealed tubes have a surface roughness of Ra < 0.4μm, effectively preventing fluid fouling and maintaining high heat exchange efficiency over a long period. Furthermore, there is no oxide scale residue, resulting in a more uniform anti-corrosion protective film.
304 vs 316 Heat Exchanger Tube
Choose 316 for heat exchanger tubes in harsh, chloride-heavy (seawater, de-icing salts) or acidic environments because its 2-3% molybdenum content significantly prevents pitting and crevice corrosion. Choose 304 for fresh water or mild chemical settings where a lower initial cost is the priority.
