Samia Pipes and Tubes is a trusted manufacturer and supplier of Stainless Steel 317 Tubing, based in Tunis, Tunisia. The company is known for supplying high-performance tubing engineered for demanding industrial environments. Stainless Steel 317 tubing offers superior corrosion resistance, particularly against aggressive chemicals and acidic media, due to its higher molybdenum content. Samia Pipes and Tubes ensures strict quality control, precise dimensional tolerances, and excellent surface finish. With a commitment to reliability, timely delivery, and customer satisfaction, the company serves chemical, petrochemical, marine, and power generation industries worldwide.
Stainless Steel 317 Tubing is a molybdenum-containing austenitic stainless steel alloy containing 18–20% chromium, 11–15% nickel, and 3–4% molybdenum. The higher content of molybdenum offers improved resistance to pitting, crevice corrosion, and general corrosion, particularly in acidic and chloride-containing environments. The tubing possesses tensile strength ranging from 515–760 MPa and yield strength of around 205 MPa. It also possesses good mechanical properties at higher temperatures and is ideal for forming, welding, and fabricating under harsh service conditions.
