Manufacturers of 347H Stainless Steel Welded Tubes designed for high-temperature and high-pressure applications. Stabilized with niobium and higher carbon content, 347H offers excellent resistance to intergranular corrosion, oxidation, and thermal fatigue in demanding industrial environments.
Our 347H Stainless Steel Welded Tubes are engineered
for high-temperature applications that demand enhanced mechanical
strength, long-term stability, and excellent corrosion resistance.
With a higher carbon content than standard 347 grade, 347H stainless
steel provides superior creep strength and improved performance under
prolonged exposure to elevated temperatures.
Stabilized with niobium, 347H effectively prevents carbide
precipitation, ensuring outstanding resistance to intergranular
corrosion even in welded and heat-affected zones. These tubes also
offer excellent resistance to oxidation and scaling, maintaining
structural integrity in severe thermal and oxidizing environments.
Commonly used in power generation plants, heat exchangers,
petrochemical refineries, chemical processing units, and other
high-temperature industrial systems, our 347H stainless steel welded
tubes deliver reliable, long-lasting performance. Available in a wide
range of sizes and customizable specifications, they provide a
high-performance solution for demanding operating conditions.
Our 347H Stainless Steel Welded Tubes are widely supplied
across India, including Mumbai and other major industrial hubs,
supporting power plants, refineries, chemical industries, and
high-temperature process systems that require superior strength,
oxidation resistance, and long-term durability.
In the Middle East, countries such as Iraq, Kuwait, Jordan, Lebanon,

are supplied to Italy, Spain, Germany, the United Kingdom
(England, Wales, Scotland, and Ireland), Russia, Ukraine,
Kazakhstan, Turkey, France, Greece, and Austria, serving power
plants, heat exchangers, chemical processing units, and
heavy industrial applications.
In Africa, industries in Morocco, Algeria, Libya, Egypt, Nigeria,
Sudan, Chad, Senegal, Kenya, Somalia, Zambia, South Africa, and
Namibia depend on our 347H stainless steel welded tubes
for their high resistance to oxidation, scaling, and extreme
temperature conditions.
In the Americas, our products are supplied to the United States,
Brazil, Argentina, Mexico, and Canada, supporting power generation,
petrochemical processing, oil & gas, and high-temperature
industrial systems.
Our reach extends across the Asia-Pacific region, including
Sri Lanka, Malaysia, Singapore, Philippines, Thailand, Vietnam,
and Australia, where 347H stainless steel welded tubes are widely
used in thermal processing plants, refineries, and heavy-duty
industrial environments.
Wherever your project is located—whether in Doha, Dubai, London,
Moscow, or New York—Seminox Pipes and Tubes delivers premium
347H Stainless Steel Welded Tubes manufactured
in strict compliance with international quality standards.
Our global presence reflects the trust industries place in our
ability to supply high-strength, corrosion-resistant, and
high-temperature stainless steel welded tube solutions for
critical industrial applications worldwide.
Higher carbon content enhances creep strength and mechanical stability, making 347H suitable for prolonged high-temperature service.
Stabilized with niobium to prevent intergranular corrosion, especially after welding and exposure to elevated temperatures.
Maintains structural integrity and strength under continuous high-temperature and thermal cycling conditions.
Performs reliably in oxidizing environments with strong resistance to scaling and surface degradation at elevated temperatures.
Manufactured using advanced welding technology to ensure uniform weld quality, dimensional accuracy, and long-term reliability.
Widely used in heat exchangers, power plants, petrochemical refineries, furnaces, and thermal processing systems.
347H Stainless Steel Welded Tubes are manufactured using premium high-carbon chromium-nickel stainless steel coils stabilized with niobium. Advanced forming and welding technologies ensure uniform wall thickness, excellent weld integrity, precise dimensional accuracy, and superior strength for prolonged high-temperature service.
Each 347H welded tube undergoes rigorous quality inspections including weld seam examination, Eddy Current Testing (ECT), dimensional verification, Positive Material Identification (PMI), and detailed visual inspection to ensure resistance to oxidation, scaling, and intergranular corrosion in high-temperature and pressure environments.
Our 347H Stainless Steel Welded Tubes are manufactured in compliance with ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and applicable ASTM, EN, and international standards, ensuring consistent quality, safety, and reliability for heat exchangers, power plants, petrochemical refineries, and high-temperature industrial systems.
