Manufacturers of UNS N04400 Nickel Alloy Seamless Tubes engineered for heat exchangers, condensers, seawater systems, chemical processing, and marine applications requiring excellent corrosion resistance, high strength, and outstanding performance in acidic and alkaline environments.
Our UNS N04400 Nickel Alloy Seamless Tubes (commonly known as
Monel 400) are engineered for demanding industrial applications where
excellent corrosion resistance and high mechanical strength are required.
Manufactured from a nickel-copper alloy, these tubes exhibit outstanding
resistance to seawater corrosion, acids, alkalis, and a wide range of chemical
environments.
The seamless construction ensures a smooth internal surface, minimizing pressure
drops and enhancing fluid flow efficiency in critical systems. These tubes maintain
their strength and toughness across a wide temperature range, making them ideal for
heat exchangers, condensers, marine piping, and chemical processing equipment.
Widely used in marine, oil & gas, chemical processing, power generation, and
offshore industries, our UNS N04400 nickel alloy seamless tubes undergo rigorous
quality control and testing to meet international performance standards. They
provide a reliable, durable, and cost-effective solution for applications exposed
to corrosive and high-stress operating conditions.
Our pipes and tubes are trusted in Mumbai and other major industrial cities across India, supporting critical sectors such as petrochemical, marine, 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, desalination, seawater handling, and chemical processing projects. We are also a preferred supplier in Qatar (Doha), Bahrain, Syria, Azerbaijan, and Georgia, where corrosion resistance and material 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 aggressive chemical and marine 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 exceptional resistance to corrosion, seawater exposure, and extreme environmental conditions.
In the Americas, our products serve the United States, Brazil, Argentina, Mexico, and Canada, supporting oil & gas, marine engineering, 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 marine, offshore, and industrial heat transfer applications.
Industries in Australia benefit from the durability and corrosion resistance of our pipes and tubes, particularly in marine, mining, desalination, and water treatment sectors.

Fully seamless manufacturing ensures excellent structural integrity, uniform wall thickness, and a smooth internal surface for reliable performance in critical applications.
UNS N04400 nickel alloy offers outstanding resistance to seawater, hydrofluoric acid, sulfuric acid, alkalis, and a wide range of corrosive chemical environments.
Maintains excellent mechanical strength and toughness from sub-zero temperatures up to elevated service conditions without embrittlement.
Designed to perform reliably under high internal pressures and thermal fluctuations in heat exchangers, condensers, and process systems.
Highly resistant to stress corrosion cracking in chloride-rich and marine environments, making it ideal for offshore and seawater systems.
Manufactured under strict quality control systems to deliver extended service life, reduced downtime, and lower total lifecycle costs in aggressive operating conditions.
UNS N04400 Nickel Alloy Seamless Tubes are manufactured using advanced seamless tube forming and controlled heat treatment processes. The nickel–copper alloy composition ensures excellent corrosion resistance, high mechanical strength, and uniform metallurgical structure, making these tubes suitable for aggressive chemical, marine, and offshore environments.
Each seamless tube undergoes stringent inspection and testing including Eddy Current Testing, Hydrostatic Pressure Testing, Positive Material Identification (PMI), dimensional verification, and detailed visual inspection to ensure structural integrity, material conformity, and defect-free performance.
Manufactured in compliance with ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and PED 2014/68/EU requirements, ensuring adherence to international quality management systems, environmental regulations, occupational safety standards, and pressure equipment directives.
