Ojas Pipes and Tubes is a well-respected manufacturer and supplier of high-performance Incoloy Boiler Tubing, located in Kolkata, India. These tubes are made from top-quality Incoloy alloys like 800, 800H, 800HT, and 825, specifically designed to resist high-temperature oxidation, carburization, and corrosion. Renowned for their remarkable thermal stability and mechanical strength, Incoloy boiler tubes are perfect for high-pressure and high-heat settings. Ojas produces these tubes in line with global standards such as ASTM B407 and B163, catering to industries like power generation, petrochemicals, and refineries, where durable and heat-resistant boiler tubing is crucial for essential operations.
Incoloy Boiler Tubing generally contains 30–46% Nickel, 19–23% Chromium, along with varying amounts of Iron, Titanium, and Aluminum based on the specific grade. These alloys provide excellent resistance to oxidation, high creep strength, and thermal fatigue resistance. The tubes showcase tensile strength ranging from 500–750 MPa, yield strength between 200–450 MPa, and elongation of 30–45%. Incoloy tubing retains its structural integrity even when exposed to high temperatures and harsh environments for extended periods. With impressive metallurgical stability and weldability, Incoloy boiler tubes are perfect for high-temperature steam applications, superheaters, and reheaters in demanding thermal conditions.
