Manufacturers of UNS N08800 Nickel Alloy Seamless Tubes (Alloy 800) engineered for high-temperature and high-pressure service in heat exchangers, condensers, petrochemical processing, and power generation systems requiring excellent resistance to oxidation, carburization, and thermal fatigue.
Our UNS N08800 Nickel Alloy Seamless Tubes (commonly known as
Alloy 800) are engineered for high-performance industrial applications
operating under extreme temperatures and aggressive chemical environments.
Manufactured from a nickel–iron–chromium alloy, these tubes provide excellent
resistance to oxidation, carburization, and sulfidation, along with outstanding
mechanical strength at elevated temperatures.
The seamless construction ensures a smooth internal surface, reducing pressure
drops and enhancing fluid flow efficiency in critical systems. These tubes retain
their structural stability and corrosion resistance during prolonged exposure to
high heat, making them ideal for heat exchangers, furnaces, condensers, and
power generation equipment.
Widely used in aerospace, petrochemical, power generation, and chemical processing
industries, our UNS N08800 nickel alloy seamless tubes undergo rigorous quality
control and testing to meet international performance standards. They offer a
reliable, durable, and cost-effective solution for applications requiring
long-term performance in harsh thermal and corrosive conditions.
Our pipes and tubes are trusted in Mumbai and other major industrial cities across India, supporting critical sectors such as petrochemical, power generation, chemical processing, and heavy infrastructure. In the Middle East, countries including Iraq, Kuwait, Jordan, Lebanon, Saudi Arabia, Yemen, Oman, and the UAE (Abu Dhabi, Dubai, Al Ain, Ajman, Sharjah, and Ras Al Khaimah) rely on our products for oil & gas, energy, desalination, and high-temperature industrial projects. We are also a preferred supplier in Qatar (Doha), Bahrain, Syria, Azerbaijan, and Georgia, where material stability and performance reliability are essential.
In Europe, our pipes and tubes are extensively supplied to Italy, Spain, Germany, the United Kingdom (England, Wales, Scotland, and Ireland), Russia, Ukraine, Kazakhstan, Turkey, France, Greece, and Austria. These regions value our precision manufacturing, alloy consistency, and long-term performance in high-temperature and chemically aggressive operating environments.
Across Africa, industries in Morocco, Algeria, Libya, Egypt, Nigeria, Sudan, Chad, Senegal, Kenya, Somalia, Zambia, South Africa, and Namibia depend on our pipes and tubes for their resistance to corrosion, thermal stress, and extreme environmental conditions.
In the Americas, our products serve the United States, Brazil, Argentina, Mexico, and Canada, supporting oil & gas, power generation, aerospace, chemical processing, and heavy manufacturing sectors.
In the Asia-Pacific region, countries such as Sri Lanka, Malaysia, Singapore, Philippines, Thailand, and Vietnam rely on our high-performance nickel alloy tube solutions for energy systems, industrial heat transfer, and high-temperature processing applications.
Industries in Australia benefit from the durability and heat resistance of our pipes and tubes, particularly in mining, power generation, chemical processing, and water treatment sectors.
