Incoloy 825 Tees

Incoloy 825 Tees are crucial pipe fittings, manufactured by Zeron Fastners, specifically used to divide or combine fluid flow in a pipeline, creating a branch line at a 90-degree angle to the main line. These fittings are forged from the high-performance nickel alloy Incoloy 825 (UNS N08825), which is alloyed with molybdenum, copper, and titanium. This exceptional composition ensures outstanding resistance to a wide range of corrosive attacks, including immunity to stress-corrosion cracking in chloride media and superior defense against reducing acids like sulfuric and phosphoric acid. Zeron Fastners provides these tees in both Equal Tee (all outlets the same size) and Reducing Tee (branch outlet is smaller) configurations. They are indispensable for establishing reliable and long-lasting branching points in severe service piping systems within chemical processing, oil and gas, and fertilizer production industries.
