Wherever you operate—Doha, Dubai, London, or New York—Seminox Pipes & Tubes delivers premium-quality ASTM A213 Stainless Steel Seamless High Precision & Heat Exchanger Tubes, manufactured to international standards for durability, reliability, and long-term performance in critical service environments.
Manufactured through seamless hot extrusion and cold drawing to ensure uniform wall thickness, tight dimensional tolerances, and smooth internal surfaces for efficient fluid flow and heat transfer performance.
Available in ASTM A213 TP304, TP304L, TP316, TP316L, TP321, TP347, and other austenitic stainless steel grades to suit corrosive, high-temperature, and pressure-critical service conditions.
Molybdenum-bearing and stabilized stainless steel grades offer strong resistance to pitting, oxidation, and chemical attack in aggressive industrial, marine, and chemical processing environments.
Designed for continuous service in boilers, superheaters, and heat exchangers, maintaining mechanical strength and metallurgical stability at elevated operating temperatures and pressures.
Smooth bore finish and consistent metallurgy reduce fouling and enhance thermal conductivity, improving system efficiency and operational reliability.
Built for durability with reduced maintenance requirements and lower lifecycle costs in continuous-duty, corrosive, and high-temperature industrial service environments.
ASTM A213 Stainless Steel Seamless Tubes are manufactured using hot extrusion and cold drawing processes to achieve precise dimensional accuracy, uniform wall thickness, and superior surface finish. Tubes are solution annealed and heat treated in accordance with ASTM A213 / ASME SA213 requirements to ensure optimal mechanical properties, corrosion resistance, and metallurgical stability for high-temperature and high-pressure service in boilers, superheaters, and heat exchangers.
Each tube undergoes mandatory testing and inspection as per ASTM A213 / ASME SA213, including chemical composition analysis, tensile and mechanical property testing, flattening and flaring tests, hydrostatic pressure testing or non-destructive electric testing (Eddy Current / Ultrasonic), dimensional verification, and detailed visual inspection to ensure compliance, structural integrity, and reliable performance under elevated temperature and pressure conditions.
Tubes are manufactured in accordance with ASTM A213, ASME SA213, EN 10216-5, and applicable international standards. Full material traceability is maintained and products are supplied with EN 10204 3.1 / 3.2 certification, along with compliance to ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and PED 2014/68/EU requirements for quality management, environmental responsibility, occupational safety, and pressure equipment conformity.
