Ayten Tube Fittings is a reliable manufacturer and supplier of Hastelloy Tube Fittings based in Addis Ababa, Ethiopia. We focus on creating high-performance fittings that excel in corrosive and high-pressure environments. Our Hastelloy Tube Fittings are meticulously engineered to provide outstanding resistance to both oxidizing and reducing agents, making them perfect for critical industries. Crafted from top-quality materials like Hastelloy C22, C276, and B2, these fittings guarantee exceptional mechanical strength, leak-proof performance, and a long lifespan. At Ayten Tube Fittings, we offer a diverse selection, including compression, instrumentation, and flare fittings, all designed to meet global standards for chemical processing, marine, and power generation applications.
Hastelloy Tube Fittings are primarily made up of nickel, molybdenum, and chromium, with small amounts of iron, tungsten, and cobalt added in. This unique alloy offers remarkable resistance to pitting, crevice corrosion, and stress-corrosion cracking. The mechanical properties include a tensile strength ranging from 690 to 785 MPa, a yield strength of about 275 to 355 MPa, and an elongation of up to 45%, ensuring durability even in extreme conditions. These fittings retain their strength at high temperatures, have low thermal expansion, and provide consistent dimensional stability and weldability, making them ideal for harsh chemical and marine environments.
