Hastelloy Pipe
Hastelloy pipes supplied by Rose Metal Industries are premium nickel-alloy piping solutions engineered for the most demanding corrosive and high-temperature environments. Manufactured, stocked and exported by Rose Metal Industries, these pipes are available in multiple Hastelloy grades (commonly C-276, C-22, B-2 and related alloys) and are stocked to serve clients across Tamil Nadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry) and the Andaman & Nicobar Islands, as well as international markets. Their combination of corrosion resistance and mechanical integrity makes them a preferred choice for chemical, petrochemical, marine and power industries..
Our Hastelloy pipes are produced to international standards and offered in seamless and welded forms to match project requirements. Typical specifications supplied by Rose Metal Industries follow commonly accepted industry norms (ASTM/ASME equivalents), and we provide a range of schedules, diameters and custom lengths. Pipes are available in pipe-specific product forms with appropriate surface treatments (hot-finished, pickled & passivated, polished) and undergo dimensional and NDT/inspection as requested to ensure fit-for-purpose performance..
Chemically, Hastelloy alloys combine a high nickel base with significant alloying additions such as molybdenum, chromium and sometimes tungsten and cobalt (grade-dependent). This carefully balanced composition gives Hastelloy pipes outstanding resistance to pitting, crevice corrosion, and stress-corrosion cracking in both oxidizing and reducing environments — including strong acids, chlorinated media and seawater. That chemical robustness is why Hastelloy piping is specified for aggressive process streams, desalination, and offshore systems..
Mechanically, Hastelloy pipes deliver a useful balance of strength and ductility. Depending on grade and heat treatment, typical tensile and yield strength levels support high-pressure and high-temperature service while maintaining good elongation for fabrication and welding. In practice this means Hastelloy pipes can be formed, welded and integrated into complex systems — heat exchangers, reactors, and process skids — without sacrificing long-term reliability in corrosive service. Rose Metal Industries supplies material with full traceability and test documentation (MTC/PMI) to satisfy engineering and procurement specifications.
