Description
Gnee Steel (Tianjin) Co., Ltd. is one of the most professional manufacturers and suppliers of ASTM A213 Grade TP316L Stainless steel heat exchanger tubes in China. With abundant experience, we warmly welcome you to wholesale customized ASTM A213 Grade TP316L Stainless steel heat exchanger tubes from our factory. For price consultation, contact us.
ASTM A213 TP316L stainless steel tubes are specifically engineered for high-performance applications such as heat exchangers, boilers, superheaters, and condensers.
GNEE supplies ASTM A213 / ASME SA213 TP316L (UNS S31603) stainless steel heat exchanger tubes manufactured through seamless and welded processes. With a low carbon content of up to 0.03%, TP316L minimizes carbide precipitation during welding, making it an ideal choice for thick-wall components. The tubes undergo solution annealing above 1040°C (1900°F), followed by rapid water quenching or air cooling to relieve stress and restore corrosion resistance.
According to ASTM A213 standards, TP316L heat exchanger tubes provide a tensile strength of ≥485 MPa and excellent high-temperature stability, ensuring reliable continuous operation in demanding heat transfer environments. Compared with conventional stainless steel grades, TP316L can extend service life by 3–5 times, significantly reducing maintenance frequency, replacement costs, and production downtime for customers.
TP316L seamless tubes are available in outer diameters ranging from 12–159 mm, wall thicknesses from 1.0–10 mm, and lengths from 1–12.9 meters, with customized lengths available upon request. Pipe ends can be supplied as plain ends, beveled ends, or threaded ends. U-bends, fins, and PVC coating protection can also be customized according to project requirements.
We strictly follow ASTM A1016 standards for dimensional tolerance control. Every tube undergoes 100% eddy current testing before shipment. Third-party inspections from organizations such as SGS or BV are also welcome.

Procurement advice: Confirm wall thickness type: ASTM A213 defaults to minimum wall thickness. If you require average wall thickness, be sure to specify this when requesting a quote, otherwise it will affect costs and production.
ASTM A213 TP316L Pipe Export Case
Regarding ASTM A213 TP316L pipes, I think you might be interested in a project we just completed last month.
We delivered 2500 heat exchanger tubes (19.05mm x 2.11mm x 6000mm) to a chemical plant in Italy. The customer was particularly concerned about minimum wall thickness and intergranular corrosion (ASTM A262 Class E standard).
We provided full MTC EN 10204 3.1 certification, and all pipes passed third-party ultrasonic testing without any defects. I've attached photos of the pipe markings and wooden crate packaging for your reference.
NDT - Non-Destructive Test
According to ASTM A213 and A1016 standards, TP316L heat exchanger tubes typically require the following tests:
* Flattening Test: Ensures the tube does not crack under pressure.
* Flaring Test: Verifies the tube's expansion performance during heat exchanger tubesheet installation.
* Hydrostatic Test: Each tube undergoes a pressure test to ensure no leakage.
* Eddy Current Test: Inspects surface and near-surface defects (the most common non-destructive testing method for heat exchanger tubes).
* Ultrasonic Test: Used to detect internal defects for thicker wall materials or those with extremely high requirements.
End Types and Packaging
Ends: Plain, beveled, or threaded
Packaging: Bundled in PE fabric, wooden cases, or seaworthy export packaging
