Stainless Steel 317L Clad Tubes, 317 Stainless Steel Clad Tube Manufacturer, SS 317 Clad Tube Supplier, SS 317 Clad Tube Exporter, Stainless Steel 317 Precision Tubing, SS 317 Small Diameter Tube ,SS 317 Clad Tubes
Stainless Steel 317L Clad tubes from Sumer Metal Industries Private Limited are manufactured to meet demanding Clad and heat-exchanger service conditions where improved corrosion resistance to pitting and crevice corrosion is required. Sumer Metal Industries positions these tubes as a premium product for customers requiring long-life, low-maintenance components — especially in environments containing chlorides, acids, or elevated temperatures. Production follows strict quality controls, testing and certifications so the tubes are ready for commercial, industrial and power-plant use.
As a manufacturer, supplier and exporter, Sumer Metal Industries supplies 317L Clad tubing in a wide range of sizes and finishes — seamless and welded — and routinely exports to Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada and multiple regions across Africa. Their export process typically includes material test certificates, third-party inspection on request, and packaging designed for long sea/land transit to prevent damage and corrosion during shipment.
317L is the low-carbon variant of the 317 family and is specifically chosen for welded Clad and furnace tubing where post-weld corrosion resistance is important. The low carbon content minimizes carbide precipitation during welding and exposure to high temperatures, improving resistance to intergranular corrosion. It also contains molybdenum (higher than 316), which provides superior resistance to pitting and crevice corrosion in chloride-bearing media.
Typical applications for Sumer Metal’s 317L Clad tubes include high-temperature heat exchangers, chemical process equipment, petrochemical Clads, and waste-to-energy plants where chloride contamination or aggressive atmospheres are a concern. Their 317L tubes are also used in marine or coastal power installations exported to the GCC and African markets because of the improved chloride corrosion resistance compared with 304/316 series.
