Sumer Metal Industries Private Limited is a leading manufacturer, supplier, and exporter of high-quality Stainless Steel 347 and 347H Condenser Tubes. The company has established a strong presence in international markets, exporting to countries including Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada, and several regions across Africa. Their products are recognized for reliability, durability, and compliance with global standards.
The SS 347 and 347H Condenser tubes are widely used in high-temperature applications due to their excellent resistance to intergranular corrosion. These tubes contain niobium (columbium), which stabilizes the stainless steel and prevents carbide precipitation, ensuring long-lasting performance in critical industries such as power generation, chemical processing, and petrochemical sectors.
Sumer Metal Industries manufactures these tubes in a variety of sizes and forms, including seamless, welded, ERW, and fabricated tubes. Customers can choose from multiple diameters, wall thicknesses, and lengths, with finishes ranging from bright annealed to polished and mirror finishes. The company also provides tubes with plain ends, beveled ends, or threaded ends to meet specific industrial requirements.
The chemical composition of SS 347 and 347H tubes is carefully controlled. SS 347 contains a maximum carbon of 0.08%, while SS 347H has a higher carbon content between 0.04–0.10% for improved high-temperature strength. Both grades include chromium (17–20%), nickel (9–13%), manganese, silicon, and niobium as major alloying elements, with iron as the balance, ensuring superior corrosion resistance and mechanical stability.
