Inconel 600, 601, 625, and 718 Pipes & Tubes are among the most widely used nickel-chromium-based superalloys, known for their outstanding resistance to heat, oxidation, and corrosion in the most demanding industrial environments. These alloys are highly preferred in industries such as petrochemicals, aerospace, marine engineering, power generation, and chemical processing due to their ability to withstand extreme temperatures and aggressive chemical exposure.
Inconel 600 Pipes & Tubes (UNS N06600) offer excellent resistance to oxidation and carburization at elevated temperatures. They are widely used in heat exchangers, furnace components, chemical processing equipment, and marine environments where both mechanical strength and chemical stability are required. Its versatility makes it a top choice for industries that demand reliability under continuous high-heat and corrosive conditions.
Inconel 601 Pipes & Tubes (UNS N06601) are a modified version of Inconel 600 with added aluminum content, providing superior resistance to high-temperature oxidation and scaling. These pipes and tubes are particularly useful in thermal processing equipment, gas turbines, and aerospace applications. Their structural stability at high temperatures ensures long service life even in demanding operations such as heat treating and combustion systems.
Inconel 625 Pipes & Tubes (UNS N06625) are known for their exceptional strength, excellent fatigue resistance, and outstanding protection against pitting, crevice corrosion, and chloride-induced stress cracking. They are extensively used in seawater systems, nuclear reactors, aerospace components, and chemical plants. Inconel 625 is highly resistant to a wide variety of corrosive media, making it ideal for marine and offshore engineering.
Inconel 718 Pipes & Tubes (UNS N07718) are a precipitation-hardenable nickel-chromium alloy with significant additions of molybdenum, niobium, and iron. Known for its outstanding tensile, fatigue, and creep-rupture strength at temperatures up to 700°C, Inconel 718 is widely used in aerospace engines, nuclear reactors, gas turbines, and high-performance automotive components. It combines weldability with superior mechanical properties, making it one of the most advanced and versatile superalloys in the market.
Across all these grades, Inconel Pipes & Tubes are manufactured in seamless, welded, ERW, and fabricated forms, adhering to international standards such as ASTM, ASME, and DIN. They are available in a wide range of sizes, wall thicknesses, and lengths to meet diverse industrial needs. Whether required for high-pressure fluid transportation, structural applications in harsh marine conditions, or high-performance aerospace components, Inconel Pipes & Tubes deliver unmatched reliability and durability.
With their superior metallurgical properties, these alloys ensure longer service life, reduced maintenance, and enhanced safety in critical operations. For industries that require the perfect balance of strength, corrosion resistance, and high-temperature stability, Inconel 600, 601, 625, and 718 Pipes & Tubes are the ultimate solution.
