Manufacturers and suppliers of ASTM A-688 Stainless Steel Welded Heat Exchanger & Condenser Tubes, engineered for chemical processing, power generation, oil & gas, food processing, pharmaceuticals, and general corrosion in high-temperature and pressure service environments.
Our ASTM A-688 Stainless Steel Welded Heat Exchanger & Condenser Tubes
are engineered for demanding industrial environments where high thermal efficiency,
corrosion resistance, and long-term service reliability are essential.
ASTM A-688 covers austenitic stainless steel tubing grades such as
TP304, TP304L, TP316, TP316L, TP321, and TP347, which provide excellent
resistance to oxidation, general corrosion, and scaling in elevated temperature
and pressure service conditions.
The precision welded construction ensures consistent wall thickness, smooth internal
surfaces, and reliable dimensional tolerances, reducing pressure loss and improving
heat transfer efficiency in critical thermal systems. These tubes perform reliably
in chemical, petrochemical, power generation, and process industry applications.
Widely used in heat exchangers, condensers, boilers, reactors, and process piping,
our ASTM A-688 tubes are manufactured and tested to meet international standards,
delivering a durable, high-performance, and cost-effective solution for high-temperature
and corrosive operating environments.
Our ASTM A-688 Stainless Steel Welded Heat Exchanger & Condenser Tubes are trusted across major industrial cities in India and throughout the Middle East, including the UAE, Saudi Arabia, Qatar, Kuwait, Oman, Bahrain, Iraq, and Jordan, supporting oil & gas, water treatment, power generation, chemical processing, 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 A-688 austenitic stainless steel welded tubes are valued for their corrosion resistance, dimensional precision, and reliable performance in high-temperature and high-pressure thermal systems.
Across Africa, the Americas, and the Asia-Pacific region, our ASTM A-688 stainless steel heat exchanger and condenser tubes support chemical plants, petrochemical facilities, power stations, marine systems, and heavy manufacturing industries, delivering dependable performance in corrosive, high-temperature, and continuous-duty operating environments.
Wherever you operate—Doha, Dubai, London, Houston, Singapore, or New York— Seminox Pipes & Tubes delivers premium-quality ASTM A-688 Stainless Steel Welded High Precision Heat Exchanger & Condenser Tubes, manufactured and certified to international standards for durability, traceability, and long-term performance in critical thermal and process service applications.
Manufactured in accordance with ASTM A-688 specifications using high-frequency electric resistance welding (ERW), followed by solution annealing and pickling to ensure uniform wall thickness, precise dimensional tolerances, and smooth internal surfaces for consistent heat transfer and fluid flow performance.
Produced in austenitic stainless steel grades such as TP304, TP304L, TP316, and TP316L, providing excellent resistance to general corrosion, oxidation, and chemical attack in thermal, marine, and industrial processing environments.
Designed to withstand elevated temperatures and operating pressures commonly encountered in heat exchangers, condensers, boilers, and petrochemical processing systems.
Smooth bore finish and consistent weld integrity enhance thermal conductivity, reduce fouling tendencies, and improve long-term efficiency in continuous-duty heat exchanger and condenser applications.
Each tube undergoes Eddy Current Testing (ECT) or Hydrostatic Testing to verify weld soundness, pressure integrity, and compliance with ASTM A-688 quality and performance requirements.
Engineered for extended operational durability, reduced maintenance, and dependable performance in power generation, chemical processing, petrochemical plants, refineries, and marine heat transfer systems.
ASTM A-688 Austenitic Stainless Steel Welded Tubes are produced using high-precision Electric Resistance Welding (ERW / HFIW) followed by full solution annealing and pickling or bright annealing. This process ensures a homogeneous microstructure, excellent corrosion resistance, and uniform mechanical properties across both the base metal and weld seam, delivering consistent dimensional accuracy for critical heat exchanger, condenser, and high-temperature service applications.
Each tube undergoes comprehensive quality control including Eddy Current Testing (ECT) of the full weld seam, Hydrostatic or Non-Destructive Pressure Testing, Positive Material Identification (PMI), chemical analysis, mechanical testing, dimensional verification, and 100% visual inspection. These procedures ensure full compliance with ASTM A-688 / ASME SA-688 requirements and reliable performance in high-pressure, high-temperature, and corrosive service environments.
Manufactured in accordance with ASTM A-688 / ASME SA-688, EN 10217-7, ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and PED 2014/68/EU directives. Tubes are supplied with EN 10204 3.1 / 3.2 Mill Test Certificates (MTC), ensuring full material traceability, regulatory compliance, and acceptance for EPC, refinery, petrochemical, power generation, and industrial heat transfer projects worldwide.
