Sumer Metal Industries Private Limited is a manufacturer, supplier and exporter of high-performance nickel-iron-chromium alloys including Inconel 800, 800H and 800HT boiler tubes. The company supplies seamless and welded tube products engineered for elevated-temperature service and corrosion resistance, and ships regularly to Gulf countries (Oman, Qatar, Saudi Arabia, the UAE, Kuwait), to Europe (Spain, Germany), North America (USA, Canada) and to several regions across Africa. Sumer Metal emphasizes quality control, full traceability (heat/lot certificates) and bespoke supply options to meet EPC and boiler fabricator requirements.
Product focus: Inconel 800 family alloys (often sold under the Incoloy/Inconel 800 trade names) are widely used for heat exchangers, superheaters, reheaters, furnace components and other high-temperature boiler and process applications. Alloy 800 is a general-purpose grade with good resistance to oxidation and carburization; 800H and 800HT are variants heat-treated or with controlled carbon that provide improved strength at elevated temperatures for long-term service.
Manufacturing & finish: Sumer Metal offers these tubes in seamless and welded constructions, in annealed, solution-annealed or specified heat-treatment conditions. Typical finishes include pickled and passivated, bright annealed, or custom finishes for ease of welding/fabrication. Tubes are supplied with standard inspection (visual, dimensional) and can be supplied with NDT (eddy current, PMI, UT) and third-party inspection on request.
Applications & performance: The alloy family is selected where combined resistance to high temperature oxidation, good mechanical strength and formability are required. Typical applications include fossil and combined-cycle boilers (superheater and reheater tubes), petrochemical furnaces, air preheaters, and other heat-transfer equipment operating up to several hundred °C. 800H and 800HT are preferred where higher creep-strength or long-time exposure above ~700°C is expected.
