Manufacturers of 347 Stainless Steel Seamless High Precision & Heat Exchanger Tubes engineered for high-temperature, high-pressure, and corrosive service in heat exchangers, and chemical processing systems.
Our 347 Stainless Steel Seamless High Precision & Heat Exchanger Tubes
are engineered for superior performance in high-temperature and corrosive
service environments. Manufactured from niobium (columbium) and tantalum
stabilized austenitic stainless steel, these tubes offer excellent resistance
to intergranular corrosion and carbide precipitation during prolonged exposure
to elevated temperatures.
The seamless, high-precision construction ensures uniform wall thickness,
exceptional structural integrity, and smooth internal surfaces that enhance
heat transfer efficiency and fluid flow in critical heat exchanger and
condenser systems. Grade 347 also provides superior creep strength and
resistance to thermal fatigue, making it well-suited for continuous
high-pressure and high-temperature operations.
Widely used in petrochemical, power generation, chemical processing,
refinery, and heavy industrial applications, our 347 stainless steel
seamless tubes undergo rigorous quality control and testing to meet
international standards, delivering long-term reliability, corrosion
resistance, and cost-effective performance in demanding thermal
and industrial environments.

Fully seamless manufacturing ensures tight dimensional tolerances, uniform wall thickness, and smooth internal surfaces for optimized heat transfer efficiency and reliable performance in critical heat exchanger and condenser systems.
Niobium (columbium) stabilization prevents carbide precipitation in heat-affected zones, ensuring superior corrosion resistance during prolonged exposure to elevated temperatures.
Provides enhanced creep resistance and mechanical stability under continuous high-temperature and high-pressure service conditions in industrial and power generation environments.
Designed to withstand thermal cycling and high internal pressures in boilers, heat exchangers, condensers, and process piping without compromising structural integrity.
Offers excellent resistance to oxidation and a wide range of corrosive chemical media, making it suitable for aggressive petrochemical and industrial processing applications.
Manufactured under stringent quality control systems to deliver extended operational life, reduced maintenance requirements, and lower total lifecycle costs in demanding thermal and industrial service environments.
347 Stainless Steel Seamless High Precision & Heat Exchanger Tubes are manufactured using advanced seamless tube forming, cold drawing, and controlled solution annealing processes. The niobium and tantalum stabilized austenitic stainless steel composition ensures excellent resistance to intergranular corrosion, high-temperature strength, and a uniform metallurgical structure, making these tubes ideal for petrochemical, power generation, and high-temperature process environments.
Each seamless tube undergoes rigorous inspection and testing including Eddy Current Testing (ECT), Hydrostatic or Pneumatic Pressure Testing, Positive Material Identification (PMI), dimensional and surface finish verification, chemical composition analysis, and detailed visual inspection to ensure compliance with ASTM and ASME standards and defect-free performance.
Manufactured in accordance with ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and PED 2014/68/EU requirements. All tubes are supplied with EN 10204 3.1 Test Certificates, ensuring full traceability, compliance with international quality systems, and adherence to pressure equipment and safety directives.
