Ojas Pipes and Tubes is a well-respected manufacturer and supplier of top-quality Hastelloy EFW (Electric Fusion Welded) Pipes, based in Kolkata, India. These pipes are crafted from high-performance Hastelloy alloys like C-276, C-22, and B2, which are renowned for their outstanding corrosion resistance and strength in harsh environments. Ojas is committed to ensuring that its EFW pipes adhere to international quality and performance standards, providing excellent weld integrity, precise dimensions, and remarkable durability. These pipes find extensive use in critical sectors such as chemical processing, marine, aerospace, and power generation, where dependable performance under extreme chemical and thermal conditions is crucial.
Hastelloy EFW Pipes are mainly made up of 55–62% Nickel, 14–22% Chromium, and 15–17% Molybdenum, with some Iron, Tungsten, and Cobalt added based on the alloy grade. This unique composition gives them exceptional resistance to both oxidizing and reducing agents, strong acids, and corrosion caused by chlorides. In terms of mechanical properties, these pipes boast a tensile strength ranging from 690–785 MPa, a yield strength of 280–355 MPa, and an elongation of up to 45%. The EFW process enables the production of larger diameter pipes with robust, clean welds, making them perfect for high-pressure and high-corrosion applications across various industrial settings.
