Product Description

ASME SA213 / ASTM A213 TP316L Stainless Steel Seamless Tube Heat Exchanger Tube

YUHONG GROUP specializes in manufacturing high‑performance heat exchanger tubes, and ASTM A213 TP316L (1.4404) stainless steel seamless tube is one of our most sold materials. This austenitic grade offers outstanding corrosion resistance – especially against chlorides, pitting, and acidic media – combined with excellent weldability and creep strength.
Every tube is produced to strict ASTM A213 standards, bright annealed, solution annealed and pickled for a smooth internal/external surface that maximizes heat transfer efficiency. To guarantee absolute reliability in critical services (chemical, petrochemical, pharmaceutical, marine, and power generation), we supply 100% hydrostatic tested (HT) and 100% eddy current tested (ET) tubes, ensuring zero leaks and no hidden defects. Thanks to our rigorous quality control and competitive manufacturing, YUHONG brand heat exchanger tubes have been exported to more than 85 countries worldwide, earning a strong reputation for consistency, durability, and on‑time delivery.

100% HT / ET" – Non‑Destructive Testing (NDT)
This is a critical requirement for heat exchanger tubes. It means every length of tube undergoes both hydrostatic testing and eddy current testing.

Test	Method	Purpose
Hydrostatic Test (HT)	Tube filled with water at specified pressure (e.g., 10–20 MPa, per ASTM A213)	Check for leaks, burst strength, and overall integrity
Eddy Current Test (ET)	Electromagnetic coil passes through tube; detects changes in impedance	Find surface & near‑surface defects (pits, cracks, inclusions, wall thinning)

*Every linear metre of every tube is tested – not just random samples. This is standard for high‑reliability heat exchanger tubes.

Application

Heat Exchangers & Condensers
Boiler & Superheater Tubes

It's genuine 321H — titanium-stabilized, so no worries about sensitization or intergranular corrosion during welding. Our welder said it welded nicely with no cracking.

Been running about 6 months now in cyclic service. No leaks, no failures. Heat transfer still where it should be.

We checked a few before installation — wall thickness consistent, roundness good. Welded in without problems.
