Stainless Steel 317 Welded Tubes

Kamal Steels is a leading manufacturer, supplier, stockist, and exporter of Stainless Steel 317 Welded Tubes, supplying premium-quality welded tubing solutions for chemical processing, pulp & paper plants, fertilizer industries, petrochemical facilities, marine engineering, pharmaceutical manufacturing, and other highly corrosive industrial applications. Manufactured from Stainless Steel 317 (UNS S31700 / WNR 1.4449), our welded tubes are produced in accordance with ASTM A249, ASTM A269, ASTM A270, ASTM A554, and ASME SA249 standards, ensuring exceptional dimensional accuracy, superior weld quality, outstanding corrosion resistance, and reliable mechanical performance. Stainless Steel 317 contains higher molybdenum content than SS 316, providing significantly improved resistance to pitting, crevice corrosion, and aggressive chemical attack.

Our Stainless Steel 317 Welded Tubes are manufactured using premium-quality stainless steel strips that are precision roll-formed and automatically welded using advanced TIG/ERW welding technology. The tubes are subsequently solution annealed, pickled, straightened, polished, and thoroughly inspected to achieve smooth surface finishes, excellent dimensional tolerances, and extended service life. These welded tubes provide outstanding resistance to sulfuric acid, chlorides, phosphoric acid, and other aggressive chemical media, making them ideal for heat exchangers, condensers, pressure vessels, chemical reactors, process piping, marine equipment, and pollution control systems.

At Kamal Steels, we maintain a comprehensive inventory of ASTM A249 Stainless Steel 317 Welded Tubes in various outside diameters, wall thicknesses, schedules, surface finishes, and custom lengths to meet urgent domestic and international project requirements. Every tube undergoes rigorous quality inspections, including Positive Material Identification (PMI), Chemical Analysis, Mechanical Testing, Hydrostatic Testing, Eddy Current Testing, Dimensional Inspection, Surface Finish Inspection, and Visual Inspection before dispatch. With certified quality, competitive pricing, export-standard packaging, and prompt worldwide delivery, Kamal Steels has established itself as a trusted manufacturer and supplier of Stainless Steel 317 Welded Tubes for critical corrosion-resistant industrial applications across global markets.

Stainless Steel 317 Welded Tubes are specially engineered for applications requiring superior corrosion resistance in highly aggressive chemical environments. Compared to Stainless Steel 316, Grade 317 contains a higher percentage of molybdenum, providing significantly improved resistance to pitting, crevice corrosion, and chemical attack. Manufactured using premium-quality stainless steel strips and advanced TIG/ERW welding technology, these tubes offer outstanding dimensional accuracy, smooth surface finishes, and reliable long-term performance in demanding industrial applications.

One of the major advantages of Stainless Steel 317 Welded Tubes is their exceptional resistance to sulfuric acid, phosphoric acid, chlorides, and various corrosive chemicals. Their excellent weldability, high mechanical strength, and outstanding oxidation resistance make them suitable for heat exchangers, condensers, chemical processing equipment, pulp & paper plants, fertilizer industries, petrochemical facilities, marine engineering, pharmaceutical manufacturing, and pollution control systems. These welded tubes also provide excellent fabrication characteristics, allowing easy forming, bending, machining, and welding.
