Inconel 718 Pipe
Typical applications of Inconel 718 Pipes include heat exchangers, turbine engine piping, chemical reactors, offshore and marine piping, power generation systems, and high-temperature process lines. Our extensive stock ensures prompt delivery to industries across Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry, Andaman & Nicobar Islands, while export services provide the same high-quality Inconel 718 Pipes to international clients, meeting critical performance and safety requirements..
Rose Metal Industries provides Inconel 718 Pipes with a range of dimensions, wall thicknesses, and lengths, available according to customer requirements. All products undergo rigorous inspection including positive material identification (PMI), hardness, tensile tests, and mill test certification (MTC) to guarantee quality compliance. Equivalent grades conform to ASTM, ASME, and UNS N07718 standards, ensuring global acceptance and compatibility..
In terms of mechanical properties, Inconel 718 Pipes exhibit tensile strength of 1240–1400 MPa, yield strength of 1030–1200 MPa, elongation of 15–20%, and hardness between 250–310 HB, depending on the heat treatment condition. These characteristics allow the pipes to withstand high-pressure applications in aerospace engine components, nuclear reactors, and chemical plants, ensuring long-term reliability and safety..
The chemical composition of Inconel 718 Pipes typically includes Nickel (50–55%), Chromium (17–21%), Molybdenum (2.8–3.3%), Niobium (4.75–5.5%), and minor elements like Cobalt, Iron, Carbon, Manganese, and Silicon. This unique combination provides superior resistance to oxidation, corrosion, and pitting, even in chloride-rich or high-temperature environments, making these pipes highly suitable for offshore, marine, and chemical processing industries..
