Their Inconel pipe fittings deliver long-lasting solutions, offering clients exceptional corrosion resistance, mechanical strength, and reliable service across critical applications around the globe.
Inconel pipe fittings are primarily made up of nickel (50–72%), chromium (14–23%), along with smaller quantities of iron, molybdenum, and niobium, which grant them remarkable resistance to corrosion and oxidation. These alloys maintain their strength at both high and low temperatures, with tensile strengths typically ranging from 75,000 to 150,000 psi and yield strengths between 35,000 and 125,000 psi, depending on the specific grade. Inconel fittings are known for their excellent creep and fatigue resistance, as well as their stability in harsh chemical environments. Their ability to maintain structural integrity during extreme thermal cycling makes them perfect for high-performance piping systems.
