Inox Steel India – Seamless & Welded Heat Exchanger Tubes for High-Performance Thermal Systems
Inox Steel India is one of the leading manufacturers, stockists, and exporters of Heat Exchanger Tubes produced as per ASTM A213, ASTM A269, and ASTM B163.
These tubes are engineered for high-efficiency heat transfer, corrosion resistance, and long-term reliability in industrial thermal systems working with steam, chemicals, refrigerants, and high-temperature fluids.
Our Heat Exchanger Tubes are used across:
Every tube is manufactured with precise tolerances, smooth internal surface, and superior mechanical stability to ensure optimal thermal conductivity and long lifecycle.
We supply straight tubes, U-bend tubes, finned tubes, and custom coil tubes, produced using advanced cold-drawing mills, bright annealing lines, and automated NDT inspection systems.
Heat exchanger tubes differ from boiler tubes or process tubing — their priority is thermal efficiency, corrosion resistance, and dimensional precision.
