Heat Exchange Tubing — Stainless & Carbon Steel for Condensers and Exchangers
Heat Exchange tubing is engineered for efficient thermal transfer and long, leak-tight service in condensers, coolers, and shell-and-tube heat exchangers across power, petrochem, and HVAC. Material options cover austenitic stainless (ASTM A249/A213) for corrosion resistance, duplex 2205 for elevated-chloride service, and low-carbon steels (ASTM A179/A192) for cost-effective duty. Automated welding or seamless drawing with solution anneal / appropriate heat treatment ensures tight tolerances, clean bore, and reliable tube-to-tubesheet fit.
Designed for condensers, coolers, and shell-and-tube heat exchangers requiring high thermal efficiency and corrosion resistance.
Available in stainless steel, duplex 2205, and carbon steel grades for diverse process fluids and temperature ranges.
Manufactured as seamless or automatically welded tubes with solution anneal and clean inner surface finish.
Tested by ECT, hydrostatic pressure, PMI, and dimensional inspection per ASTM / EN requirements; MTC EN 10204 3.1 available.

- Quality Control: Each Heat Exchange Tubing product is individually NDE or hydro-tested; optional PMI, mechanical, and dimensional reports with EN 10204 3.1 certificates are available.
- Flexible Supply: U-bend, polished surface grades, end machining, and export protective packing available per drawings or project specs.
Description
Heat Exchange Tubing plays a critical role in ensuring reliable and efficient thermal transfer performance. Its effectiveness depends on internal surface cleanliness, strict OD/WT tolerance for leak-tight tube-to-tubesheet joints, and corrosion- and temperature-resistant materials matched to each application. Austenitic stainless steels (304/316) provide superior corrosion resistance and ease of cleaning, Duplex 2205 offers high strength and chloride resistance for seawater and brine systems, while 321 / 347 / 309S / 310S maintain mechanical stability at elevated temperatures. For cost-effective duties, A179 / A192 low-carbon and carbon steel Heat Exchange Tubing remain reliable and durable choices.
ASTM A249 welded stainless Heat Exchange Tubing is automatically welded and fully solution-annealed to restore corrosion resistance and formability, followed by 100% NDE (Eddy Current / Eddy Defect) or hydrostatic testing. ASTM A213 / A179 / A192 seamless tubing is cold-drawn or hot-rolled and heat-treated (annealed / normalized / tempered) to achieve mechanical properties. Standard inspections include chemical composition, tensile/yield/elongation, hardness, flattening/flaring, and dimensional checks. All Heat Exchange Tubing is traceable with full MTC EN 10204 3.1 certification available on request.

Specifications Sheet
The following table shows typical dimensional tolerances and weight data for thin-wall stainless heat-exchanger tubing (ASTM A249 / A213). Values apply to standard austenitic grades and may vary slightly depending on size, process, and manufacturer. For carbon-steel or thick-wall tubes (A179 / A192), tolerances follow their respective standards.
Main Applications
Heat-exchanger tubing is widely used in condensers, coolers, and shell-and-tube exchangers across power generation, petrochemical, HVAC, desalination, and process industries. Designed for efficient thermal transfer and leak-tight tube-to-tubesheet joints, these tubes ensure long-term performance under pressure, temperature, and corrosive service conditions.
