Manufacturers and suppliers of ASTM A268 Stainless Steel Seamless High Precision & Heat Exchanger Tubes, engineered for chemical processing,high-temperature service conditions in demanding industrial environments.
Our ASTM A268 Stainless Steel Seamless High Precision & Heat Exchanger Tubes
are manufactured to meet stringent quality and performance requirements for
industrial and thermal processing applications. ASTM A268 covers ferritic
stainless steel tubing grades designed to provide excellent resistance to
oxidation, corrosion, and scaling at elevated temperatures.
The seamless, high-precision construction ensures uniform wall thickness,
tight dimensional tolerances, and smooth internal surfaces, minimizing
pressure loss and improving heat transfer efficiency in critical systems
such as heat exchangers, condensers, and boiler assemblies.
Widely used in chemical processing, power generation, food processing,
petrochemical, and industrial manufacturing sectors, our ASTM A268 seamless
tubes deliver long service life, reliable mechanical performance, and
reduced maintenance costs in both corrosive and high-temperature
operating environments.
Our ASTM A268 Stainless Steel Seamless High Precision & Heat Exchanger Tubes are trusted across major industrial cities in India and throughout the Middle East, including the UAE, Saudi Arabia, Qatar, Kuwait, Oman, and Bahrain, supporting chemical processing, power generation, water treatment, and large-scale infrastructure and EPC projects.
In Europe, we supply Italy, Germany, Spain, the United Kingdom, France, Turkey, and Eastern European markets, where our ASTM A268 stainless steel tubes are valued for reliable high-temperature performance, corrosion resistance, and dimensional precision in thermal processing and industrial service environments.

Austenitic and ferritic stainless steel grades offer strong resistance to general corrosion, scaling, and oxidation in high-temperature and chemically aggressive service environments.
Designed to maintain structural integrity under elevated temperatures, pressure variations, and thermal cycling in critical heat transfer and industrial process systems.
Smooth bore finish and consistent metallurgy improve thermal conductivity, reduce fouling, and enhance performance in heat exchangers, condensers, and boiler systems.
Engineered for dependable service in chemical processing, food production, power generation, and marine applications where corrosion resistance and temperature stability are critical.
Built for durability and extended operational life, helping lower lifecycle costs and minimize downtime in continuous-duty industrial and thermal processing applications.
ASTM A268 Stainless Steel Seamless Heat Exchanger Tubes are manufactured using precision hot finishing and cold drawing processes, followed by solution annealing and pickling to achieve a clean, homogeneous microstructure. Austenitic and ferritic stainless steel grades such as TP 304, 304L, 316, 316L, 321, 409, and 430 provide excellent resistance to oxidation, scaling, and general corrosion, ensuring consistent dimensional accuracy and reliable performance in heat exchangers, boilers, and high-temperature service applications.
Each tube undergoes comprehensive quality control including Eddy Current Testing (ECT), Hydrostatic or Air Underwater Leak Testing, Positive Material Identification (PMI), chemical composition analysis, mechanical property testing, dimensional verification, and 100% visual inspection. These procedures ensure full compliance with ASTM A268 / ASME SA268 requirements and dependable performance in thermal, corrosive, and high-stress operating environments.
Manufactured in accordance with ASTM A268 / ASME SA268, EN 10216-5, ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and PED 2014/68/EU directives. Tubes are supplied with EN 10204 3.1 Mill Test Certificates (MTC), ensuring full material traceability, regulatory compliance, and acceptance for EPC, power generation, chemical processing, and industrial heat transfer projects worldwide.
